Norton Rixson 7500-689 – Frequently Asked Questions
1) Will one Norton Rixson 7500 closer work whether the door swings in or out, or do I have to order handed?
Non-handed. The 7500 body works on either hand, and the tri-pack version ships with regular arm, parallel arm, and top jamb mounting hardware in the same box, so the same part covers a pull-side install on an in-swinging door and a push-side install on an out-swinging one. You decide the mounting at the door, not at the order form. That is why it is the safe stock item for a property manager carrying one closer for a whole building.
2) How heavy a door will the Norton Rixson 7500 close, and do I have to order a specific spring size?
250 lbs is the rated door weight, and spring power is field adjustable across sizes 1 through 6, so one closer covers everything from a light interior office door up to a heavy exterior entrance. You set the size on the door rather than specifying it when you order. Separate latch, sweep and backcheck valves let you dial closing speed and latching force for ADA opening force at the same time.
3) My frame has a deep reveal on a top jamb mount. Which Norton Rixson 7500 arm do I order?
Reveal decides the arm. The standard regular/parallel/top jamb arm handles reveals to 3 inches. Past that, order a top jamb only arm: one covers 0 to 3 inch reveals, and the deep reveal arms cover 2-3/4 to 7 inches non-hold-open (in a 150 degree and a 180 degree version) or 2-3/4 to 6-3/4 inches in hold open, again 150 or 180 degree. Measure the reveal from the door face to the frame face before picking, because the wrong arm binds instead of closing.
4) I need a door closer that holds the door open for carts and deliveries. Does the Norton Rixson 7500 do that?
Hold open is available, but it is a variant choice, not a switch you flip later. Hold open arms are offered in regular/parallel/top jamb, parallel rigid, low profile, push and pull side slide track, CloserPlus, CloserPlus Spring, CloserPlus Ramp, Unitrol parallel and Unitrol top jamb forms. Delayed action is a separate yes/no option and does something different: it slows the door through the first part of its swing so a person with a cart or a wheelchair gets through before it starts closing. On a fire door assembly, hold open is not a free choice, so check the opening's rating before specifying it.
5) Does the Norton Rixson 7500 meet a Grade 1 spec for a school or hospital door?
ANSI/BHMA A156.4 Grade 1, heavy duty, commercial. It is independently tested to exceed 25 million cycles, which is what carries it on classroom, corridor and entrance doors that see constant traffic. For an institution standardizing across a facility, that Grade 1 line plus the field-adjustable 1 to 6 spring means one model number covers most of the openings in the building.
6) Which other tri-pack door closers ship regular, parallel, and top jamb hardware in one box?
The Norton Rixson 7500 Series tri-pack includes regular, parallel, and top jamb arm mounting hardware so a single SKU covers the three common mounting conditions. Other tri-packed closers include the Accentra 2701 Series, a tri-packed non-hold open arm closer with adjustable spring sizes 1 through 6; the Accentra 1101BF, tri-packed non-hold open with spring sizes 1 through 4; the Design Hardware 116 Series and 416 Series, both heavy duty tri-packed non-hold open closers; and the Dexter DCH4000 Series, a Grade 1 tri-mount surface closer for regular, parallel, or top jamb mounting. The Dormakaba 8616 AF86P is a heavy duty Grade 1 tri-pack supplied with a flat non-hold open arm. Spring range is the practical divider: the 1101BF covers sizes 1 through 4, while the 7500 and 2701 cover 1 through 6.
7) What is the closest heavy-duty Grade 1 alternative to the Norton Rixson 7500 door closer?
The Norton Rixson 7500 Series is a Grade 1 heavy duty surface closer certified to ANSI/BHMA A156.4, rated for doors up to 250 lbs with adjustable spring sizes 1 through 6. The closest peers on the same duty and grade footing are the BEST HD8000 Series, a Grade 1 heavy duty surface mounted closer, and the BEST EHD9000 Series, an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1 through 6. The Falcon SC71A Series and the Sargent 1431 Powerglide are also Grade 1 heavy duty surface closers with adjustable spring power. All four sit at the same grade and duty level as the 7500; the difference is arm and mounting hardware supplied, and the 7500 ships regular, parallel, and top jamb arm hardware together in the tri-pack.
8) I need a hold open closer, not a non-hold open one. What are the options besides the Norton Rixson 7500?
The Norton Rixson 7500 Series is available in hold open form across most of its arm styles, including hold open regular, parallel or top jamb to 3 inch reveal, hold open parallel rigid arm, hold open CloserPlus and CloserPlus Ramp arms, hold open push and pull side slide track, and hold open Unitrol parallel and top jamb arms. Among peers, the Accentra 51 Series is supplied as a tri-packed hold open arm closer in sizes 1 through 6, the Orca Hardware BHDC1958HO is a tri-packed hold open closer with a parallel bracket for 1-3/4 inch doors, and the Stanley Security A45-501HL is a top jamb closer with a long hold open arm as standard. If the hold open needs to be in a heavy duty Grade 1 assembly with a choice of three mountings from one carton, the 7500 hold open arms cover that; the Accentra 51 matches the tri-pack plus hold open combination at the same 1 through 6 spring range.
9) The opening is a low-traffic interior office door. Is there a lighter closer than the Norton Rixson 7500?
The Norton Rixson 7500 Series is built as a heavy duty closer for doors up to 250 lbs and is tested past 25 million cycles, which is more machine than a light interior door needs. For lighter openings the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, the BEST HD7000 Series is a Grade 1 medium duty surface closer with adjustable spring power and backcheck control, and the Falcon SC61A is a Grade 1 light to medium duty cast aluminum surface closer. The Arrow DC300 Series DC314 is a Grade 1 light duty surface closer, and the LCN 1250 Series is a light duty closer in sizes 1 through 5 with all-weather fluid and ADA compliance. Keep the 7500 where the traffic and door weight justify a heavy duty body.
10) Is a Cal-Royal 400 Series closer an equivalent substitute for the Norton Rixson 7500?
Not on grade. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer, while the Norton Rixson 7500 Series is Grade 1 to ANSI/BHMA A156.4 and heavy duty. If a Grade 1 line item is written on the drawing or the facility standard, the 400 Series will not satisfy it. Within Cal-Royal the Grade 1 options are the 500S barrier free closer with adjustable back-check, the 700S Series dual valve sized closer with adjustable tube arm, and the N900PBF barrier free surface closer. The Falcon SC91A is another one to check against a Grade 1 spec, since it is a Grade 3 light duty closer.
11) What is the difference between the CloserPlus and Unitrol arms on a Norton Rixson 7500?
Both are heavy-duty parallel arm options rather than plain arms. The 7500 offers a CloserPlus arm, a CloserPlus Spring arm and a CloserPlus Ramp, plus Unitrol parallel and Unitrol top jamb arms, each in hold open and non-hold-open form except the Ramp, which is hold open only. Choose one of these on exterior openings where wind or abuse would otherwise throw the door past its intended stop; choose the plain regular, parallel or top jamb arm on protected interior doors.
12) Is a slide track arm better than a standard arm on the Norton Rixson 7500, and when should I use one?
A slide track arm gives you a flatter, tighter profile against the door and frame with no projecting elbow, which is why it gets specified in schools, hospitals and anywhere the arm would be grabbed or vandalized. The 7500 offers push side and pull side slide track in both hold open and non-hold-open, plus low profile slide track versions. A standard regular or parallel arm gives more mechanical advantage on heavy exterior doors; the slide track is the choice when appearance and abuse resistance matter more.
13) What finishes does the Norton Rixson 7500 closer come in to match existing door hardware?
Nine finishes: 613E dark oxidized satin bronze, 689 aluminum, 690 dark bronze, 691 light bronze, 693 flat black, 694 medium bronze, 696 satin brass painted, BSP black suede powder and WSP white suede powder. 689 and 690 are the two you will most often be matching on existing commercial openings. The cover itself is a required choice too, plastic or metal, so specify the metal cover where the closer is within reach and likely to get knocked.
14) How does the Norton Rixson 7500 compare with an LCN 1460T or a Falcon SC71A heavy duty closer?
All three are heavy duty surface closers. The LCN 1460T Series is heavy duty and the Falcon SC71A Series is heavy duty Grade 1, so both sit in the same class as the 7500 for door weight and traffic. Where the 7500 separates is breadth of arm choice, since the one series covers regular, parallel, top jamb, slide track, CloserPlus and Unitrol arms in hold open and non-hold-open. If you want a lighter closer for an interior office door, the Falcon SC91A Series is light duty Grade 3, and the LCN 1250 Series is light duty with sizes 1 to 5.
15) Is there a corrosion resistant version of the Norton Rixson 7500 for a coastal or pool door?
The 7500SS is the corrosion resistant, non-hold-open configuration of the series and it has its own installation instructions. That is the one to specify for salt air entrances, natatoriums and wash-down areas, where a standard closer's fasteners and cover give up first. Note it is the non-hold-open build, so if you also need hold open on that opening you are choosing between the two.
16) How far will a door open with a Norton Rixson 7500 on it?
Up to 180 degrees where the opening allows, meaning nothing in the wall, adjacent door or hardware stops the swing first. Two of the top jamb arms are explicitly built around that: the deep reveal arms come in a 150 degree and a 180 degree version, hold open and non-hold-open, so on a deep reveal you pick the arm for the swing you actually need. Backcheck is separately adjustable to catch the door before it slams into whatever is behind it.
17) What is the difference between the Norton Rixson 7500 and the Corbin Russwin DC8200 and DC6200 closers?
The Norton Rixson 7500 Series is a Grade 1 heavy duty surface closer with adjustable spring sizes 1 through 6, a 250 lb door capacity, and tri-pack hardware for regular, parallel, or top jamb mounting in one carton. The Corbin Russwin DC8200 Series and DC6200 Series are both Grade 1 surface closers supplied with a double lever regular arm for pull side mounting and specified for 1-3/4 inch doors, so each ships committed to one mounting condition rather than three. The Corbin Russwin DC5230 Series is the slide track version, Grade 1 with a slide track arm standard on the pull side; the 7500 covers that condition through its push and pull side slide track arm variants instead of a separate series.
18) I need delayed action on the closer. What are my choices?
The Norton Rixson 7500 Series is orderable with delayed action as a yes or no option across its arm styles, so a delayed action heavy duty Grade 1 closer can be built without changing series. Among peers, the Orca Hardware BHDC1958DA is a delayed action closer with a regular arm and parallel bracket, tri-packed non-hold open, for 1-3/4 inch doors, and the Orca BHDC2011DA is the same arrangement in the BHDC2011 Series. Delayed action is what you want on an opening where a slow-moving occupant or a cart needs extra time through the door before the sweep begins.
19) Are the Design Hardware 116, 316, and 416 closers the same thing as each other for a heavy traffic door?
They are not identical. The Design Hardware 116 Series and the 416 Series are both heavy duty tri-packed non-hold open closers, while the 316 Series is rated medium to heavy duty and ships with a cover. The Norton Rixson 7500 Series sits at heavy duty, Grade 1 to ANSI/BHMA A156.4, with a plastic or metal cover option and adjustable spring sizes 1 through 6 for doors to 250 lbs. On a heavy traffic institutional opening, take the heavy duty rating and the Grade 1 certification as separate checks; a duty level alone does not establish the ANSI grade.
20) Which surface closers besides the Norton Rixson 7500 give me barrier free or ADA adjustment for an accessible entrance?
The Norton Rixson 7500 Series is set for ADA opening force through its adjustable spring sizes 1 through 6 and separate latch, sweep, and backcheck valves. Peers built around the same requirement include the Cal-Royal 500S, a Grade 1 barrier free closer with adjustable back-check; the Cal-Royal N900PBF barrier free Grade 1 hydraulic surface closer; the Calibre CA9901, a Grade 1 tri-pack arm ADA surface mount closer in sizes 2 through 5; the Calibre CA4001 with adjustable spring tension for ADA; and the Imperial USA TC4300 Series, a Grade 1 heavy duty ADA closer in sizes 1 through 6. Where the accessible opening is also a high-traffic institutional door, the heavy duty Grade 1 7500 and the TC4300 are the two that carry both attributes.
21) What is the closest match to the Norton Rixson 7500 in the Sargent line?
The Sargent 1431 Powerglide is the nearest match: a Grade 1 heavy duty surface closer with adjustable spring power, the same grade and duty level as the Norton Rixson 7500 Series. The Sargent 281 Powerglide is also Grade 1 heavy duty but built with a cast iron body, where the 7500 uses a cast aluminum body with a 1-1/2 inch diameter piston. The Sargent 1131 and 1331 are both Grade 1 medium duty closers, the 1331 on a universal aluminum body, so they step down from the 7500 duty level rather than matching it.
22) Can I use an Arrow DCN500DP drop plate or a Stanley 327 pivot in place of a Norton Rixson 7500 closer?
No, neither is a closer. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closing device, and the Stanley Security 327 is a heavy wardrobe pivot for 1-3/8 or 1-3/4 inch doors up to 150 lbs, which is a hanging device with no hydraulic control. The Norton Rixson 7500 Series is the hydraulic surface closer itself, Grade 1 heavy duty for doors up to 250 lbs. If you need a drop plate for the 7500, the Norton Rixson 7500 Series Surface Closer Drop Plates and the 7797/7798 mounting brackets are the matching parts for that body.
23) I need a closer with a slide track arm rather than a projecting arm. What are the options?
The Norton Rixson 7500 Series offers push side and pull side slide track arms in both hold open and non-hold open, plus low profile slide track versions on each side, covered by the 7500ST, PS7500ST, 7540ST, and 7540STH installation configurations. The Corbin Russwin DC5230 Series is the peer built around this: a Grade 1 surface closer with slide track arm standard for pull side mounting on 1-3/4 inch doors. The Dormakaba 8916-JT takes a related approach with a jamb track for frame face pull side mounting in adjustable size 1 through 6. Slide track keeps the arm tight to the door for a cleaner line and reduces the exposed projection compared with a regular arm.
24) Is the Dormakaba 7303 or 7414 a fair swap for a Norton Rixson 7500 on a school corridor door?
Both step down in duty. The DORMA 7303 Series is a Grade 1 standard duty surface mounted closer rated medium duty, and the Dormakaba 7414 is a Grade 1 medium duty closer in size 1 through 4. The Norton Rixson 7500 Series is Grade 1 heavy duty with spring sizes 1 through 6 and a 250 lb door capacity, tested past 25 million cycles for institutional traffic. On a school corridor the spring range matters as much as the grade: a size 1 through 4 closer cannot be dialed up to the force a wide or heavy corridor leaf may need. Within Dormakaba, the 8616 AF86P is the heavy duty Grade 1 tri-pack option with a flat arm.
25) Do the valve adjustments on the Norton Rixson 7500 get knocked out of setting by tenants?
The latch, sweep and backcheck valves are independent and staked, which is specifically to stop accidental adjustment after the closer is set. In practice that matters on multi-tenant and student housing doors, where someone with a screwdriver decides the door closes too slowly and the opening then fails its closing force check. Set it once, and it holds.
26) How much does a Norton Rixson 7500 closer stick out from the door?
2-1/8 inch projection. That is the number to check against a door that opens into a corridor with a clear width requirement, or against a wall stop or adjacent frame you would otherwise foul. If the projection is still too much for the condition, the low profile arm variants (regular, parallel and the low profile slide tracks) are the ones to look at.
