Sargent 351 P4 BSP – Frequently Asked Questions

1) Will the Sargent 351P work on a door that opens toward me, mounted on the stop side?

Parallel arm mounting puts the closer on the push side of the door, on the door face, with the arm running back to the frame soffit. That is what the 351P is built for. If your opening needs the closer on the pull side, or on the frame face at the top jamb, the 351 body supports standard, top jamb, parallel and track mounting, so the mounting method is a matter of the arm and brackets you order rather than a different closer body. Handing is a required choice on the 351P, right hand or left hand, so determine handing at the door before you order.

2) Does the Sargent 351P door closer meet ADA opening force requirements?

The 351P is ADA compliant in all applications except push-side track applications. For an accessible interior opening that is the configuration to avoid; standard, top jamb and parallel arm mountings are fine.

3) I need the door to stay open while carts go through. Which Sargent 351 arm do I order?

Hold open is an arm choice on the 351P, not a separate closer. Friction hold open comes as the PH9, the heavy duty PH10, or the PH4 flush frame version. If you want the door stopped at a fixed point and held there, the CPSH pairs hold open with a compression stop and the PSH pairs it with a positive stop. Pick a friction arm when you want the user to be able to pull the door free by hand; pick a stop arm when the door also needs to be prevented from swinging into a wall.

4) My frame has no reveal, the stop is flush with the face. Will a parallel arm closer still mount?

That is what the flush frame arms are for. The 351P offers the P4 parallel flush frame arm, the P4A flush frame arm for use with an auxiliary holder or stop, and the PH4 flush frame friction hold open arm. On a flush frame condition, order one of those rather than the standard P9 parallel arm.

5) I need the door to stay open a few seconds for wheelchair users. Does the Sargent 351P do delayed action?

Yes. Delayed action is built into the 351 platform and is ordered as the DA device option. It holds the door near open for a period before the closing cycle begins, which is what you want at an accessible entrance, a healthcare corridor, or anywhere people move through slowly. Order DA at the same time as the arm and finish; it is a factory option on the closer, not a field accessory.

6) The opening is a low-traffic interior office door - is there a lighter closer than the Sargent 351P?

The Sargent 351P is built as a heavy-duty Grade 1 closer for highly trafficked commercial environments, which is more closer than a quiet interior office door needs. Lighter Grade 1 surface closers in the same category include the BEST SL6000 Series and the Arrow DC314 of the DC300 Series, both light duty Grade 1. The BEST HD7000 Series sits between them as a medium duty Grade 1 closer with adjustable spring power and backcheck control. The Falcon SC91A Series is light duty and Grade 3, so it is the one to check against a spec that requires Grade 1.

7) What is the closest heavy-duty Grade 1 surface closer to the Sargent 351P if the specifier will not accept Sargent?

The Sargent 351P is a Grade 1, heavy-duty surface-mounted closer. Two peers carry the same duty level and grade: the BEST HD8000 Series and the Falcon SC71A Series, both Grade 1 heavy duty surface-mount closers. The BEST EHD9000 Series is also Grade 1 heavy duty and is the extra heavy-duty build in that line with adjustable spring sizes 1-6. If the submittal calls for a heavy-duty Grade 1 surface closer, all three answer that line. Where the 351P differs is arm scope: it is ordered with a specific parallel arm from a fourteen-option range including P9 standard parallel, P10 heavy duty parallel, PS positive stop, and CPS compression stop, rather than a tri-packed arm set.

8) The door has no room for a parallel arm on the push side - what closer should be used instead of the Sargent 351P?

The Sargent 351P is ordered in a parallel arm configuration, with every arm option in its range a parallel arm - P9 standard parallel, P4 parallel flush frame, PH9 friction hold open, and so on. For a pull-side installation, the Corbin Russwin DC6200 Series is a Grade 1 surface closer with a double lever regular arm and pull side mounting, and the DC8200 Series is the same regular arm pull side arrangement in the DC8000 line; both list a 1-3/4 inch door thickness. Where the header will not take a projecting arm at all, the Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm as standard, pull side mounting.

9) I need one closer model that works regular, top jamb, or parallel without picking the arm up front - what is an alternative to the Sargent 351P?

The Sargent 351P is ordered as a parallel arm closer, with the arm selected at order time from options such as P10 heavy duty parallel, CPS compression stop, and SP10 security arm. If a single stocked part that covers all three mountings is preferred, the Dexter DCH1000 Series is a Grade 1 surface closer, tri mount for regular, parallel or top jamb, with a full cover, and the DCH4000 Series is the same tri mount Grade 1 arrangement. The Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring, medium duty, and the Arrow DCN325 is a Grade 1 surface closer with a regular/parallel tri-pack arm and adjustable spring size 1 to 6, light duty. A tri-pack ships the brackets to mount either way; the 351P instead lets the parallel arm itself be specified as a stop, hold open, or security arm.

10) What is the difference between the compression stop and positive stop arms on a Sargent 351 closer?

Both stop the door short of a wall, and both are offered on the 351P: CPS is the heavy duty parallel arm with a compression stop, PS the heavy duty parallel arm with a positive stop, and CPSH and PSH are the hold open versions of each. A compression stop cushions the door at the stop point, a positive stop is a hard mechanical limit. If the opening does not need the closer to do the stopping, the plain P9 standard parallel arm or the heavy duty P10 keeps the assembly simpler.

11) Can I add a Sargent 351P to a door that already has an overhead stop or holder?

Yes, and there are dedicated brackets for it. The P3 offset bracket gives 1 inch of offset and the P3A gives 1-3/4 inches, both for use with an auxiliary holder or stop. The P4A flush frame arm is the flush frame version for the same situation. Ordering one of these keeps the closer arm clear of the overhead device already on the frame.

12) How do I keep a door closer from being vandalized or pulled off in a detention or school corridor?

Order the 351P with the SP10 heavy duty security arm. It is the security arm option in the 351 arm range, and it pairs with the closer's heavy duty build, which Sargent rates Grade 1 for highly trafficked commercial openings. For added resistance to the closer body itself being removed, the TB through bolt option for 1-3/4 inch doors bolts the closer through the door rather than relying on screws into the door face alone.

13) What door thickness does the Sargent 351P through bolt option cover?

The TB through bolt package for the 351P is sized for a 1-3/4 inch door, which is the standard commercial thickness. Through bolting is the choice on hollow metal or on a wood door where screws into the face alone will not hold under heavy traffic. If you do not need it, the closer ships in its standard configuration.

14) Will a Sargent 351P hold its adjustment on an exterior door through winter and summer?

The Powerglide fluid in the 351P is built to keep working through extreme heat and cold without readjustment, which is the failure most people see on a cheaper closer at an exterior opening: it drags in January and slams in July. The valves face front, so if it ever does need tuning, you adjust from the front of the closer rather than pulling the door off or working blind behind the cover.

15) Can I change the arm on a Sargent 351 closer later, or am I locked into what I ordered?

The arms are interchangeable on the 351. The closer body stays and the arm assembly comes off, so a friction hold open PH9 can be swapped for a positive stop PS, or a standard P9 for a security SP10, without replacing the closer. That matters on a fleet of doors where one opening turns out to need hold open and the rest do not.

16) What is the closest equivalent to a Sargent 351P from another brand?

For a Grade 1 heavy duty surface closer, the direct peers ZenSupply stocks are the BEST HD8000 Series and the BEST EHD9000 Series, both Grade 1 heavy duty, the Falcon SC71A heavy duty Grade 1, and the Dormakaba 8900 Series (8916 JT), Grade 1 heavy duty. The Corbin Russwin DC8000 Series is a Grade 1 surface closer for 1-3/4 inch doors, supplied with a double lever regular arm for pull side mounting rather than the parallel arm setup the 351P is configured for.

17) I want one closer I can mount three different ways across a building. Is the Sargent 351P the right pick?

The 351 body takes standard, top jamb, parallel and track mounting, but the 351P is ordered as a parallel arm configuration with a specific arm and a specific hand, so each door still gets a defined order. If you want a closer shipped tri-packed so the installer decides at the opening, look at the Dexter DCH1000 or DCH4000, both Grade 1 tri-mount for regular, parallel or top jamb, the Norton Rixson 8501A Grade 1 tri-mount, or the Arrow DCN325 tri-pack. Those trade the 351P's heavy duty rating in some cases, so match duty level to traffic before standardizing.

18) Can a Sargent 351P be ordered with both delayed action and a hold open arm?

Yes, they are separate choices. Delayed action is the DA device option on the closer body, and hold open is a property of the arm, such as the PH9 friction hold open or the PSH positive stop hold open. Specifying DA does not use up the arm choice. Handing is still required either way, right hand or left hand.

19) Which closers besides the Sargent 351P offer a hold open arm?

The Sargent 351P covers hold open through its arm selection - CPSH heavy duty parallel hold open with compression stop, PSH with positive stop, and the friction hold open arms PH9, PH10 and PH4. Peers that list a hold open function include the Accentra 51 Series with a tri-packed hold open arm and the Orca Hardware BHDC1958 hold open version with parallel bracket, which lists a 1-3/4 inch door thickness. The Stanley Security A45-501HL is a long hold open arm for standard, top jamb mounting. Note that the Accentra 1101BF and 2701 Series are both specified as tri-packed non-hold open arm, so they are not the ones to order where the door must stand open.

20) I need delayed action on the closer - which models besides the Sargent 351P have it?

The Sargent 351P carries a delay function and is ordered with the DA delayed action device option alongside the standard and TB through bolt options. Among the peers, the Orca Hardware BHDC1958 delayed action version pairs a regular arm with a parallel bracket and lists a 1-3/4 inch door thickness, and the BHDC2011 delayed action version is the same arrangement in that series. Both Orca delayed action models are specified as tri-packed non-hold open arm, so a delayed close and a hold open are not combined on them the way the 351P handles hold open through its arm choice.

21) Are the Stanley 327 and 341 wardrobe pivots an alternative to the Sargent 351P?

No. The Stanley Security 327 is a heavy wardrobe pivot for doors 1-3/8 inch or 1-3/4 inch up to 150 pounds, and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch. Pivots hang and swing a door; they do not close it. The Sargent 351P is a surface-mounted hydraulic door closer that controls the closing cycle, meets ADA requirements in all applications except push-side track applications, and includes a delay function. An opening that needs both would take a pivot and a closer, not one in place of the other.

22) The building already runs Norton Rixson closers - what matches the Sargent 351P on an aluminum storefront opening?

The Norton Rixson 1600BC Series is a heavy-duty Grade 1 aluminum storefront closer with tri-style mounting, which is the Norton Rixson answer to a storefront door needing a heavy-duty Grade 1 closer like the Sargent 351P. The Norton Rixson 1600 Series 1601P is Grade 1 as well but medium duty, with tri-mount design and 180 degree swing, and the 160 Series is Grade 1 light duty for light commercial openings. The 351P is heavy duty and Grade 1, ordered in a parallel arm configuration with finishes including EN sprayed aluminum enamel and BSP black suede powder coat.

23) Are there heavy-duty closers other than the Sargent 351P for a school or healthcare corridor?

The Sargent 351P is a heavy-duty Grade 1 closer built for schools, healthcare facilities and other high-traffic commercial buildings, and it operates in extreme heat and cold without readjustment. Other heavy-duty options in the same category include the Design Hardware 116 Series and 416 Series, both heavy duty with a tri-packed non-hold open arm, and the 316 Series, rated medium to heavy duty and supplied with a cover. The Imperial USA TC4300 Series is a heavy duty size 1-6 ADA closer. The Dormakaba 8616 is a Grade 1 heavy duty closer with a flat arm, non-hold open, tri-pack, and the Dorma 8916-JT is Grade 1 heavy duty with a jamb track and frame face mounting on the pull side.

24) Will a Cal-Royal 400 Series closer meet a spec that calls for the Sargent 351P?

Not on grade. The Sargent 351P is Grade 1; the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If the drawing calls out Grade 1, the Cal-Royal peers that hold it are the 500S barrier free closer with adjustable back-check, the 700 Series 700S dual valve sized closer with adjustable tube arm, and the N900PBF of the 900 Door Closer Series, a barrier free Grade 1 hydraulic surface closer.

25) What is an ADA-compliant parallel arm closer other than the Sargent 351P?

The Sargent 351P is ADA compliant and meets ADA requirements in all applications except push-side track applications. The Calibre CA8001P is a parallel arm size 1 ADA surface mount closer in the CA8000 Series, Grade 1, which is the direct parallel-arm ADA counterpart. The Calibre CA9901 is a Grade 1 tri-pack arm ADA surface mount closer in sizes 2-5, and the CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer. The size range is the deciding detail: the CA8001P is a fixed size 1, while the CA9901 covers 2 through 5.

26) Is an LCN closer a like-for-like swap for the Sargent 351P?

Only the heavy-duty one. The LCN 1460T Series is a heavy duty surface-mounted Grade 1 commercial closer in a powder coat finish, which lines up with the Sargent 351P as a heavy-duty closer. The other LCN peers sit lighter: the 1450 Series is medium duty with cast aluminum construction and spring sizes 1-6, the 1260 Series 1261 is light to medium duty with cast iron construction and spring sizes 1-5, and the 1250 Series is light duty, sizes 1-5, all-weather fluid and ADA compliant. The 351P is ADA compliant as well and holds its adjustment through extreme heat and cold.

27) Which closers are painted or enamel finish alternatives to the Sargent 351P?

The Sargent 351P comes in eight finishes including EN sprayed aluminum enamel, EB sprayed bronze enamel to match dark satin bronze, EAB sprayed brass enamel, BSP black suede powder coat, WSP white suede powder coat, and 10BE dark oxidized satin bronze. Peers supplied in a painted or coated finish include the DORMA 7303 Series in a painted finish, a medium duty Grade 1 closer, the Dormakaba 7414 sizes 1-4, also medium duty Grade 1 and painted, and the LCN 1460T in a powder coat finish, heavy duty. The 351P's range is the wider one for matching existing bronze hardware on a fleet of doors.

28) The opening needs a closer with an integral stop - what compares to the Sargent 351P for that?

The Sargent 351P handles the stop in the arm: the PS heavy duty parallel arm with positive stop, PSH the same with hold open, CPS with compression stop, and CPSH compression stop with hold open. Among the peers, the Corbin Russwin DC3200 is a Grade 1 regular arm surface closer in the DC3000 Series listing 1-3/4 inch door thickness, and the Dexter DCL2000 and DCM1000 Series are Grade 1 tri mount surface closers - all regular or tri-mount arm builds rather than a parallel arm with a built-in stop. For a stop that mounts separately, the 351P also offers the P3 1 inch and P3A 1-3/4 inch offset brackets for use with an auxiliary holder or stop.

29) What is a traditional-look surface closer if the Sargent 351P is too industrial for the opening?

The Sargent 351P is a heavy-duty commercial closer for high-traffic environments. For openings where appearance leads, the Accentra 1900 Series is a traditional surface mounted door closer, and Deltana offers the DC10, DC40, DC50 and DC70 door closers. The trade-off to check before substituting: the 351P is Grade 1 and heavy duty with a delay function and a fourteen-option parallel arm range, so an opening under real traffic or under a Grade 1 callout should stay with the heavier closer.
