Dormakaba DOR-7436-ARP-SNB1-689 – Frequently Asked Questions
1) Will the Dorma 7436 door closer work on a wood door, or is it only for hollow metal?
Hollow metal, aluminum, and wood doors are all covered. The 7400 Series was built for the door types used in commercial construction, and the 7436 ships with both wood and machine screws so you have the right fastener for a wood door or a metal frame without a separate order.
2) Do I have to order a left hand or right hand version of the Dorma 7436?
No handing to specify. The 7436 is non-handed, and it mounts regular arm, top jamb, or parallel arm, so the same closer covers either swing. What you do pick is the mounting position for the opening and the arm type, since the closer ships with the parallel arm bracket set as standard.
3) Which arm do I order on the Dorma 7436 if I want the door to stay open?
Order the FHP friction hold open arm. The other choice, ARP, is a round non hold open arm, which lets the door close every time. Friction hold open is the one that parks the door at the position you set. Both arms come in all six finishes. Skip hold open on any fire rated opening, since the door has to be free to close.
4) Is the Dorma 7436 Grade 1, and is it heavy enough for a school or hospital corridor?
ANSI/BHMA Grade 1 certified, in an aluminum body, rated medium duty. That is the right pick for interior corridor and office doors in an institutional building. For an entrance or a high abuse door where the traffic is constant, step up to a heavy duty body such as the BEST HD8000 Series or the Norton Rixson 1600 Series aluminum storefront closer, both Grade 1.
5) What should I use instead of the Dorma 7436 on a high-traffic exterior entrance?
For an abused or high-traffic exterior leaf, step up to a heavy duty body: the BEST EHD9000 is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1-6, the Sargent 1431 Powerglide is a heavy duty Grade 1 surface closer with adjustable spring power, and the Falcon SC71A is a heavy duty Grade 1 surface mount closer. The Dorma 7436 is a medium duty Grade 1 closer with an adjustable size 3 to 6 spring and adjustable backcheck, which suits hollow metal, aluminum, and wood doors in general commercial construction.
6) What is a straight equivalent to the Dorma 7436 door closer from another brand?
The Dorma 7436 is a Grade 1, medium duty surface mounted closer that mounts regular, top jamb, or parallel arm. The closest same-spec peers are the BEST HD7000, a Grade 1 medium duty surface mounted closer, the Sargent 1131, a Grade 1 medium duty adjustable surface closer, and the Norton Rixson 8501A, a Grade 1 tri-mount surface closer with adjustable size 1-6 spring. All three land on the same Grade 1 medium duty footing as the 7436 and cover the same three mounting positions, so a spec calling for a Grade 1 medium duty tri-mount closer is satisfied by any of them.
7) The Dorma 7436 is heavier than I need for an interior office door. What is a lighter option?
For a lighter opening, the Falcon SC91A is a Grade 3 light duty surface mount cast aluminum closer, the BEST SL6000 is a Grade 1 light duty surface mounted closer with adjustable spring sizes, and the Norton Rixson 160 is a Grade 1 light duty light commercial surface closer with an adjustable spring. The Dorma 7436 sits at medium duty with a size 3 to 6 spring range, so it is built for a heavier or higher-traffic leaf than any of those three.
8) Is the Cal-Royal 400 Series a substitute for the Dorma 7436?
Not where the spec is written to a grade. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer, while the Dorma 7436 is ANSI/BHMA Grade 1 certified. Both are surface applied hydraulic closers and will look similar on the door, but a submittal calling for Grade 1 will not accept the 400 Series. Grade 1 alternates in the same commercial hydraulic family include the Cal-Royal 700S dual valve sized closer and the Dexter DCH4000 tri-mount surface closer.
9) I need delayed action for a door people move carts through. Does the Dorma 7436 do that?
The 7436 controls sweep and latch speeds through two independent valves and has an adjustable backcheck, which cushions an abusively opened door rather than holding it slow off the stop. For a true delayed action closer, the Orca BHDC1958DA and the Orca BHDC2011DA are delayed action closers with a regular arm and parallel bracket, both for 1-3/4 inch doors and supplied with a tri-packed non-hold open arm. Backcheck and delayed action solve different problems, so do not swap one for the other on a spec.
10) Does the Dorma 7436 come with a cover, or is the body exposed?
The body ships bare unless you add one. Cover is a separate selection: COV slim plastic cover or FC full plastic cover, with no cover as the default. On a public corridor or a lobby most specs call for the full cover; a back of house door usually goes without.
11) Can I set different closing and latching speeds on the Dorma 7436?
Two independent valves handle sweep and latch separately, so you can slow the swing across the room and still bring the door home hard enough to latch. The valves hold those speeds as temperature changes, which matters on an exterior door that sees winter. Backcheck is separately adjustable and cushions the door when someone throws it open into a wall.
12) Should I mount a surface closer parallel arm or regular arm on a commercial door?
Parallel arm puts the closer on the push side, tucked flat against the door and out of the swing, which is why it is the usual choice on a corridor or an out-swinging exterior door where the arm would otherwise stick into traffic. Regular arm mounts on the pull side and gives more efficient power for the same spring size, but the arm projects. Top jamb goes on the frame face when the door has no room for a body. The 7436 does all three out of one box and comes standard with the parallel round form arm tri-pack.
13) Which closer suits an aluminum storefront door if not the Dorma 7436?
The Dorma 7436 is rated for hollow metal, aluminum, and wood doors in commercial construction, so it is a candidate for storefront work. Where a heavier storefront unit is wanted, the Norton Rixson 1600 Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting. For a narrow top rail in a lighter commercial storefront, the Falcon SC61A is a Grade 1 light to medium duty cast aluminum surface mount closer.
14) I need a closer that holds the door open. Is the Dorma 7436 the right one?
The 7436 comes with either an ARP round non-hold open arm or an FHP friction hold open arm, so it can do either job depending on the arm chosen. If a dedicated hold open unit is preferred, the Accentra 51 Series ships with a tri-packed hold open arm in sizes 1-6, the Orca BHDC1958HO also uses a tri-packed hold open arm, and the Stanley Security A45-501HL comes with a long hold open arm standard for top jamb mounting. Note that friction hold open and a stop-arm hold open behave differently at the door, so confirm which the opening needs.
15) What is the difference between the Dorma 7436 and the Arrow DCN325?
Both are Grade 1 surface closers with adjustable spring power and tri-pack mounting. The Arrow DCN325 is a light duty closer supplied less cover with regular and parallel arm mounting and an adjustable spring size 1 to 6. The Dorma 7436 is medium duty with an adjustable spring size 3 to 6, mounts regular, top jamb, or parallel arm, and can be ordered with a slim or full plastic cover. The wider size range on the DCN325 reaches down to size 1 for narrow interior leaves; the 7436 starts at size 3.
16) The opening needs a slide track closer, not a standard arm. What replaces the Dorma 7436?
The 7436 ships by default with a parallel round form arm in a tri-pack. For a track application, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting, on doors 1-3/4 inch thick. Where a double lever regular arm on the pull side is acceptable instead, the Corbin Russwin DC6200 and DC8200 are Grade 1 surface closers in that configuration, both for 1-3/4 inch doors.
17) We are standardizing closers across a portfolio of buildings. What are the medium duty Grade 1 options besides the Dorma 7436?
On a medium duty Grade 1 standard, the peers are the BEST HD7000 with adjustable spring power and backcheck control, the Norton Rixson 1601P with tri-mount design and 180 degree swing, the Norton Rixson 8501A tri-mount with adjustable size 1-6 spring, the Sargent 1131, the Sargent 1331 with a universal aluminum body, the Falcon SC81A cast aluminum closer, and the LCN 1450 with a cast aluminum body and spring sizes 1-6. The Dorma 7436 itself is an aluminum bodied medium duty Grade 1 closer, non-handed, with adjustable spring sizes 3 to 6 and adjustable backcheck.
18) Will a cast iron closer work where the Dorma 7436 is specified?
It depends on what the spec is protecting. The Dorma 7436 has an aluminum body and is available in sprayed finishes. The Sargent 281 Powerglide is a heavy duty Grade 1 cast iron surface closer and the LCN 1261 is a light to medium duty cast iron closer with adjustable spring sizes 1-5. Cast iron bodies are a different material and a different look on the door, so on a job where finishes are being matched across openings confirm the body material against the drawing before substituting.
19) Is the Arrow DCN500DP drop plate an alternative to the Dorma 7436?
No. The Arrow DCN500DP is a parallel drop plate for the Arrow DCN500 closer, a mounting bracket rather than a closer body. The Dorma 7436 is the complete surface mounted hydraulic closer, supplied non-handed with wood and machine screws and mountable regular, top jamb, or parallel arm. If a drop plate is needed under a 7436, that is an accessory to the closer, not a replacement for it.
20) What finishes does the Dorma 7436 painted closer come in?
Six sprayed finishes: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze, and 696 satin brass. Every one of those is available with either the ARP non hold open arm or the FHP friction hold open arm, so matching the rest of the hardware on a building does not limit which arm you can use.
21) What is the difference between the Dorma 7436 and the Design Hardware 316 Series?
The Design Hardware 316 Series is a medium to heavy duty closer supplied with a tri-packed non-hold open arm and a cover included. The Dorma 7436 is medium duty, non-handed, with a parallel round form arm tri-pack as the default and a cover ordered separately as either a slim plastic cover or a full plastic cover. If the heavier end of the range matters, Design Hardware also offers the 116 Series and 416 Series as heavy duty closers with tri-packed non-hold open arms.
22) I want a closer that comes with the cover included rather than ordering one. What are the options against the Dorma 7436?
On the Dorma 7436 the cover is a separate selection, either a slim plastic cover or a full plastic cover, and it can also be taken with no cover. The Dexter DCH1000 is a Grade 1 tri-mount surface closer supplied with a full cover. Going the other way, the Arrow DCN314 and DCN325 are Grade 1 tri-pack closers supplied less cover, and the Design Hardware 316 Series comes with a cover.
