Dormakaba DOR-7305-ARP-689 – Frequently Asked Questions

1) Will the DORMA 7305 door closer work on a door that swings toward me, or do I need a different hand?
Handing isn't a factor. The 7305 is non-handed, so the same closer goes on a left- or right-hand door. It ships tri-pack, covering regular arm, top jamb, and parallel arm mounting, so you pick the application at install rather than at the order form. The round arm supplied is non-hold-open, meaning the door closes every time and won't stand open on its own.
2) Is the DORMA 7305 spring size adjustable, or is it fixed?
Fixed, not adjustable. The 7305 is a fixed size 5 closer, so the spring power is set at the factory and you cannot dial it up or down for a lighter door. That matters on the order: you have to know the door width and weight before you buy, because the only way to change power is to change closers. If you want one closer that can be tuned across a range of openings, look at an adjustable-power unit such as the Norton Rixson 8501A (adjustable size 1-6) or the Accentra 2701 Series (adjustable spring sizes 1-6).
3) Is a size 5 door closer too strong for an ADA opening?
The 7305 is listed as ADA compliant, and it's a fixed size 5. Size 5 is a high-power spring intended for wide or heavy doors, so it is normally an exterior or oversized-door choice rather than an interior barrier-free one. If your opening needs a lower opening force, a lighter fixed size or an adjustable closer is the safer specification.
4) Does the DORMA 7300 Series closer meet fire door requirements?
The 7300 Series is ANSI/BHMA A156.4 Grade 1 certified, UL and CUL listed, meets UL10C for positive pressure, and is CSFM approved. That covers the listings a fire-rated opening inspection asks for on a surface closer.
5) Does the DORMA 7305 come with the screws, or do I need to buy mounting hardware?
Wood and machine screws are included, so a standard install on a wood or hollow metal door doesn't need separate fasteners ordered. The cover is the piece that isn't automatic: the closer comes with no cover by default, and the slim plastic cover (COV) is an option you add at the order. If the closer is going somewhere it will be seen, add it.
6) Will the DORMA 7305 stand the door open when I need it to?
No. The arm supplied is a round non-hold-open arm, so the door returns closed every time. That's what you want on a fire door, and it's the wrong choice if someone wants a loading door propped. For hold open in a comparable surface closer, ZenSupply carries the Accentra 51 Series with a tri-packed hold open arm and the Orca Hardware BHDC1958 hold open with parallel bracket.
7) What is the closest equivalent to the DORMA 7305 surface closer from another manufacturer?
The DORMA 7305 is a Grade 1, medium duty, non-handed surface closer with a non-hold-open round arm, set up for regular and top jamb mounting. The BEST HD7000 is the nearest match in the set: it is also a Grade 1 medium duty surface mounted door closer, with adjustable spring power and backcheck control. Sargent's 1131 and 1331 are also Grade 1 medium duty surface closers, the 1331 built on a universal aluminum body, which matches the aluminum substrate of the 7305. Norton Rixson 8501A is a Grade 1 medium duty tri-mount closer with an adjustable size 1-6 spring. The key difference to weigh: the 7305 carries a fixed spring size 5, while the HD7000, 8501A, 1131 and 1331 are adjustable-power units, so one of those lets a single part number cover several door widths on a job.
8) I need a closer that can hold the door open. What replaces a DORMA 7305 on that opening?
The DORMA 7305 arm is a round arm non-hold open arm, so it will not park the door. For a hold-open opening, the Accentra 51 Series comes with a tri-packed hold open arm and covers sizes 1 through 6, and the Orca Hardware BHDC1958HO/PA is a hold open closer supplied with a parallel bracket for 1-3/4 inch doors. Stanley Security's A45-501HL is a top jamb closer with a long hold open arm as standard. Note that a hold-open arm is not permitted on a fire-rated opening without a listed hold-open device, so confirm the door's rating before substituting.
9) The 7305 is set up for regular and top jamb. What do I use if the closer has to go on the push side, parallel arm?
The DORMA 7305 is supplied for regular and top jamb mounting with the AR arm. When the closer has to mount parallel arm on the push side, a tri-pack unit is the direct move: the Arrow DCN314 is a Grade 1 surface closer with regular and parallel arm mounting and an adjustable spring size 1 to 4, and the Arrow DCN325 is the same tri-pack arrangement with an adjustable spring size 1 to 6. Dexter's DCH4000, DCM1000 and DCL2000 are Grade 1 tri-mount closers covering regular, parallel and top jamb from one part number, and the Norton Rixson 1601P is a Grade 1 tri-mount closer with a 180 degree swing. Orca's BHDC1958RA/PA ships a regular arm with a parallel bracket for 1-3/4 inch doors.
10) Is the DORMA 7305 enough closer for a high-traffic exterior entrance, or should I step up?
The DORMA 7305 is a Grade 1 commercial closer rated medium duty with an aluminum body and adjustable backcheck. For abusive exterior traffic, the set has heavier options: the BEST EHD9000 is an extra heavy-duty Grade 1 closer with adjustable spring sizes 1-6, the BEST HD8000 is a Grade 1 heavy duty unit, the Sargent 1431 Powerglide is a Grade 1 heavy duty closer with adjustable spring power, and the Sargent 281 Powerglide is a heavy duty Grade 1 closer with a cast iron body. LCN's 1460T is a Grade 1 heavy duty closer in a powder coat finish, and the Falcon SC71A is a Grade 1 heavy-duty surface closer. For an aluminum storefront entrance specifically, the Norton Rixson 1600BC is a Grade 1 heavy duty tri-style-mount storefront closer.
11) I am standardizing closers across a facility on Grade 1. Which alternatives to the DORMA 7305 hold the same certification?
The DORMA 7305 is ANSI/BHMA A156.4 Grade 1 certified, UL and CUL listed, meets UL10C for positive pressure, and is CSFM approved. Grade 1 peers that hold the same A156.4 grade include Corbin Russwin DC3200, DC5230, DC6200 and DC8200; Cal-Royal 500S and 700S; Calibre CA9901, CA4001, CA5501 and CA8001P; Dexter DCH1000, DCH4000, DCL2000 and DCM1000; Falcon SC61A, SC71A and SC81A; BEST SL6000, HD7000, HD8000 and EHD9000; Sargent 1131, 1331, 1431 and 281; and Norton Rixson 160, 1601P, 8501A and 1600BC. One to check twice if the spec says Grade 1: the Cal-Royal 400 Series is Grade 2, and the Falcon SC91A is Grade 3.
12) The opening needs delayed action so a cart or a wheelchair can clear. Does the DORMA 7305 do that, and what does if not?
The DORMA 7305 controls the door with two independent valves for sweep and latch speed plus an adjustable backcheck, and it is ADA compliant, but delayed action is a separate function. For an opening that needs the door to pause before it starts to close, the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket for 1-3/4 inch doors, and the BHDC2011DA/PA is the same delayed action arrangement in the BHDC2011 series. Both are tri-packed non-hold open arm units, so the arm behavior otherwise matches the 7305.
13) I want one closer part number that covers every door width on the job instead of ordering the 7305 by size. What are my options?
The DORMA 7305 carries a fixed spring size 5, so each door width is a separate order. Adjustable-power closers let one part number cover a range: the Accentra 2701 covers adjustable spring sizes 1 through 6 with tri-pack mounting and a non-hold open arm, the Accentra 1101BF covers adjustable sizes 1 through 4 with tri-pack mounting, the Arrow DCN325 is adjustable 1 through 6 and the DCN314 adjustable 1 through 4, the Imperial USA TC4300 is a Grade 1 heavy duty ADA closer adjustable 1 through 6, the Norton Rixson 8501A is a Grade 1 tri-mount adjustable 1 through 6, and the Calibre CA9901 is a Grade 1 tri-pack arm closer covering sizes 2 through 5. The trade is that adjustable units require the spring to be set at the door, where the 7305 arrives at its size.
14) Will the DORMA 7305 hold up on a high-traffic entrance?
It's rated medium duty and built for commercial use, with a Grade 1 aluminum body. Medium duty suits offices, corridors, and moderate-traffic openings. For a heavy-traffic main entrance or an abused door, step up to a heavy-duty unit such as the BEST HD8000 Series, the BEST EHD9000 extra heavy-duty, or the Sargent 1431 Powerglide.
15) Can I slow the door down at the end of the swing so it stops slamming into the wall?
Yes, that's the backcheck, and it's adjustable and standard on the 7300 Series. It cushions the opening swing when someone throws the door open. Separately, two independent valves let you set sweep speed and latch speed on their own, and those speeds stay constant as temperature changes, so a door tuned in summer doesn't crawl in winter.
16) What's a direct alternative to the DORMA 7300 Series medium duty surface closer?
Closest like-for-like medium duty Grade 1 surface closers ZenSupply carries are the BEST HD7000 Series, the Falcon SC81A, the Sargent 1131, and the Norton Rixson 1601P, which is tri-mount with 180 degree swing. All are medium duty Grade 1 like the 7300. The practical difference from the 7305 is spring power: the 7305 is a fixed size, while several of those alternatives are adjustable.
17) Is a surface mounted closer like the DORMA 7300 the right type, or should I be looking at a slide track or concealed closer?
A surface applied rack and pinion closer like the 7300 mounts on the face of the door or frame with an exposed arm, which is the fastest retrofit on an existing opening because there's no door or frame prep. The tradeoff is the projecting arm. Where the arm has to stay tight to the door for appearance or to avoid a hazard, a slide track unit such as the Corbin Russwin DC5230 is the alternative. Where the door itself needs to accept the closer body, that's a different install entirely and the 7300 is not it.
18) Can the DORMA 7305 be mounted on the push side of the door?
Yes, through top jamb mounting, which puts the closer on the frame above the door on the push side. The 7305 ships tri-pack for regular, top jamb, and parallel arm applications, and it's non-handed, so one part number covers pull side and push side. The AR arm supports the regular and top jamb mountings.
19) The 7305 size 5 is more closer than my interior office doors need. What is the lighter option?
The DORMA 7305 carries a fixed spring size 5 at medium duty, which is aimed at wider or heavier leaves. For light interior traffic, the BEST SL6000 is a Grade 1 light duty surface closer with adjustable spring sizes, the Norton Rixson 160 Series is a Grade 1 light duty closer with an adjustable spring for light commercial work, and the LCN 1250 is a light duty closer in sizes 1 through 5 with all-weather fluid and ADA compliance. Falcon splits the same ground two ways: the SC91A is a Grade 3 light duty cast aluminum closer and the SC61A is Grade 1 light to medium duty cast aluminum. On the adjustable units you set spring power down at the door rather than ordering a fixed size, which is the practical difference from the 7305.
20) What looks like a substitute for the DORMA 7305 but will not work on the door?
A few items sit close to surface closers in a search but do not replace one. The Stanley Security 327 is a heavy wardrobe pivot for 1-3/8 or 1-3/4 inch doors up to 150 lbs, and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 to 1-3/8 inch - both are hanging hardware, not closing devices, so neither controls the door's return. The Stanley 57-0100 is a box of 100 steel machine screws for architectural hinges. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer body. The 7305 is itself supplied with wood and machine screws for its mounting.
21) The 7305 uses an exposed round arm. What closes the door on a slide track instead?
The DORMA 7305 uses a round arm non-hold open arm on regular and top jamb mounting, which is a conventional projecting arm. Where the detail calls for a track, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm as standard, pull side mounting, for 1-3/4 inch doors. If the objection is the arm geometry rather than the track itself, Corbin Russwin's DC6200 and DC8200 are Grade 1 surface closers with a double lever regular arm on pull side mounting for 1-3/4 inch doors, and the DC3200 is a Grade 1 regular arm surface closer for the same door thickness.
22) Which closers besides the DORMA 7305 are stated as ADA compliant for a barrier-free opening?
The DORMA 7305 is ADA compliant. Others in the same class that state barrier-free or ADA compliance: the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF is a Grade 1 hydraulic barrier free surface closer, the Calibre CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer, the Calibre CA8001P is a Grade 1 parallel arm size 1 ADA closer, the Calibre CA9901 is a Grade 1 tri-pack arm size 2-5 ADA closer, the LCN 1250 is ADA compliant in sizes 1 through 5, and the Imperial USA TC4300 is a heavy duty size 1-6 ADA closer. Where an opening has a maximum opening force limit, an adjustable-power unit gives you room to tune it at the door.
23) The DORMA 7305 body is aluminum. Which alternatives use cast iron instead?
The DORMA 7305 uses an aluminum substrate, which is what keeps the 7300 body compact. If the spec or the environment calls for cast iron, the LCN 1261 is a surface closer with cast iron construction and adjustable spring sizes 1 through 5 at light to medium duty, and the Sargent 281 Powerglide is a Grade 1 heavy duty cast iron surface closer. On the aluminum side of the same comparison, the LCN 1450 is a medium duty cast aluminum closer with spring sizes 1 through 6, and Falcon's SC81A is a Grade 1 medium duty cast aluminum closer, both of which match the 7305 on material and duty level.
24) Are the Design Hardware 116, 316 and 416 closers interchangeable with the DORMA 7305?
All three Design Hardware series use a tri-packed non-hold open arm, which matches the DORMA 7305 on arm function - it is a non-hold open arm as well. Where they part company is duty: the 7305 is medium duty, the Design Hardware 316 is medium to heavy duty and carries a cover, while the 116 and 416 are both heavy duty. The 7305 also arrives at a fixed spring size 5 and is non-handed for regular, top jamb and parallel arm applications, so confirm which mounting the Design Hardware unit's tri-pack supports before you swap it onto the same jamb.
25) I have residential-look doors in a small building. Is a DORMA 7305 the right closer, or is there something simpler?
The DORMA 7305 is a commercial Grade 1 closer with an adjustable backcheck and separate sweep and latch valves, built for openings that see commercial traffic. For a lighter, simpler installation the Deltana DC10, DC40, DC50 and DC70 are plain door closers, and the Accentra 1900 Series is a traditional surface mounted closer. If the building has a fire-rated or code-governed opening in it, note that the 7305 is the unit carrying the ANSI/BHMA A156.4 Grade 1 certification, UL and CUL listing, UL10C positive pressure and CSFM approval, so keep it on those doors even if the lighter units go elsewhere.
26) What finishes does the DORMA 7305 surface closer come in, and can I match it across a building?
Three sprayed finishes: 689 aluminum, 695 dark bronze, and 696 satin brass. Those are the standard painted closer finishes, so matching a fleet of openings across a property is a matter of specifying one code and repeating it. Body substrate is aluminum under the finish.
27) I ordered the DORMA 7305 without the cover. Which closers include a cover in the box?
On the DORMA 7305 the slim plastic cover is a separate selection, so the unit can be taken with or without it. Where a covered closer is wanted as one item, the Dexter DCH1000 is a Grade 1 tri-mount surface closer supplied with a full cover, and the Design Hardware 316 Series is a medium to heavy duty closer with a cover, using a tri-packed non-hold open arm like the 7305. Going the other way, the Arrow DCN314 and DCN325 are both specified less cover.
