Dormakaba 8616-AO8P-689 – Frequently Asked Questions

1) Will the DORMA 8616 door closer work on a left-hand and a right-hand door, or do I have to order handing?
The 8616 is non-handed, so one closer covers both swings. The AO8P arm shipped with it is a tri-pack: regular arm, top jamb, and parallel arm mounting in the same box, with the parallel arm bracket and an adjustable round threaded arm with lock nut. For a property manager buying spares across a building, that means one part number on the shelf regardless of which way the door swings or which face the closer lands on.
2) How heavy a door will the DORMA 8616 surface closer handle?
Rated to 180 lb door weight, with spring power adjustable across sizes 1 through 6. Size 1 covers a light interior leaf; size 6 handles a wide, heavy exterior opening. Because the power is adjustable on the closer rather than fixed by model, one 8616 covers the whole range instead of ordering a sized closer per opening. It is a heavy duty, Grade 1 closer tested to 10,000,000 cycles, which is the traffic level for a main entry or a corridor door in a school or hospital.
3) Does the DORMA 8616 closer meet ADA opening force requirements?
ADA compliant, and the reason is the adjustable spring size 1-6. On an interior barrier-free opening you dial the spring down to the low end to get under the maximum opening force, then use the closer's own valves to keep the door closing and latching. A fixed-size closer will not let you do that. Grade 1 certified to ANSI/BHMA, which is what most institutional specs call for.
4) What mounting hardware comes with the DORMA 8616, and will it work on a 1-3/4 inch hollow metal door?
Sex nuts for a 1-3/4 inch door are included, which is the standard commercial door thickness. Sex nut fastening means you drill through the door and clamp the closer from both faces, the mounting method you want on a hollow metal or wood leaf where sheet metal screws would eventually pull out under a heavy closer. The tri-pack arm and parallel arm bracket are in the box too, so nothing extra is needed for a regular arm, top jamb, or parallel arm install.
5) Will the 8616 parallel arm clear the reveal on my aluminum storefront frame?
The AO8P arm is rated for a 0 to 4 inch reveal, so it covers flush frames right through deep-set storefront and recessed openings without a drop plate. The 8600 Series is built for hollow metal, aluminum, and wood doors, so a glass front installer working aluminum entrances is inside the intended application. Beyond 4 inches of reveal, this arm is the wrong choice.
6) What does secure non-hold open mean on a door closer, and when should I not use it?
Non-hold open means the 8616 always returns the door to the closed and latched position, with no detent to park it open. That is what you want on a fire-rated opening, a stairwell, a corridor smoke door, or any entry that must not be propped. If you actually need the door to stand open, this is the wrong function and you want a hold open arm instead, such as the Accentra 51 Series or the Orca BHDC1958 hold open, both of which are tri-packed hold open arms.
7) What is the closest Grade 1 heavy duty equivalent to the DORMA 8616 if I need a different brand on the same opening?
The DORMA 8616 is a Grade 1, heavy duty surface closer with an adjustable size 1 to 6 spring. Two peers match that combination directly: the BEST EHD9000 Series is Grade 1, heavy duty, with adjustable spring sizes 1-6, and the BEST HD8000 Series is Grade 1 and heavy duty. Sargent's 1431 Powerglide is also Grade 1 heavy duty with adjustable spring power, and the Falcon SC71A is a Grade 1 heavy duty surface-mount closer. Any of the four keeps you in the same grade and duty class when a job spec calls for a different manufacturer.
8) I need a closer that holds the door open. What takes the place of the DORMA 8616 AO8P?
The 8616 AO8P is a secure non-hold open closer, so it will not park the door. For a hold open arm in the same tri-pack style of mounting, the Accentra 51 Series is a tri-packed hold open arm closer covering sizes 1-6, and the Orca Hardware BHDC1958HO/PA is a tri-packed hold open arm closer for 1-3/4 inch doors with a regular arm and parallel bracket. The Stanley Security A45-501HL is a long hold open arm for top jamb mounting.
9) I need a closer with a concealed slide track arm instead of the DORMA 8616 round parallel arm. What should I order?
The 8616 AO8P carries an adjustable parallel round threaded arm with lock nut and parallel arm bracket covering a 0 to 4 inch reveal, which is an exposed arm. If the opening calls for a slide track instead, 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. For a double lever regular arm on the pull side, the Corbin Russwin DC6200 and DC8200 are both Grade 1 for 1-3/4 inch doors.
10) Do I have to use a Grade 1 closer, or will a Grade 2 work as a substitute for the DORMA 8616?
The DORMA 8616 is ANSI/BHMA Grade 1 certified. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer, so it sits in a different certification tier and will not satisfy a drawing that calls out Grade 1. The Falcon SC91A is Grade 3 light duty. If the spec says Grade 1, stay with Grade 1 peers such as the Cal-Royal 500S barrier free closer with adjustable back-check or the Cal-Royal 700S dual valve sized closer with adjustable tube arm.
11) I need a delayed action closer for an accessible entrance rather than the DORMA 8616. What are my options?
The 8616 meets barrier-free accessibility requirements through its adjustable spring size 1-6 but is a secure non-hold open closer without a delayed action function. For delayed action, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are both delayed action closers with a regular arm and parallel bracket, tri-packed non-hold open, for 1-3/4 inch doors.
12) Does the DORMA 8616 size range matter when comparing it to closers rated size 1-4?
Yes. The 8616 adjusts across sizes 1 through 6, so one closer covers narrow interior doors up to wide heavy exterior doors and handles up to a 180 pound door. Peers capped lower cover less of that range: the Accentra 1101BF is a tri-packed non-hold open closer with adjustable spring sizes 1-4, the Arrow DCN314 is a light duty tri-pack in size 1-4, and the Calibre CA8001P is a Grade 1 parallel arm closer in size 1 only. The Calibre CA9901 covers size 2-5.
13) What is backcheck on the 8600 Series closer and why does it matter on a windy exterior door?
Backcheck is a cushion near the end of the opening swing that stops the door from being thrown into the adjacent wall, by wind or by someone shoving it. The 8616 has an adjustable backcheck, plus a backcheck positioning adjustment specifically for parallel arm mounting so the cushion starts at roughly the same point it would in a regular arm or top jamb install. On an exterior entry catching wind, this is the feature that keeps you from replacing bent arms and torn hinges.
14) What cover options can I get on the DORMA 8616, and which one do I need for a school or dorm?
Three covers: the standard slim plastic cover, a full plastic cover, and a full metal cover. The slim cover is the low-profile architectural look. The full metal cover is what you specify in a dorm, school corridor, or detention-adjacent area where a plastic cover gets kicked off and walks away. All three suit a closer body with an aluminum substrate.
15) Can I standardize a whole building on the DORMA 8616 instead of stocking several closers?
That is what the 8616 is set up for. Non-handed body, tri-pack arm covering regular, top jamb, and parallel arm mounting, adjustable spring sizes 1 through 6, and a 0 to 4 inch reveal range on the parallel arm bracket. One SKU per finish covers the light interior leaf and the heavy exterior entry, both swings, and all three mounting positions, up to a 180 lb door. Facilities and MRO buyers use that to cut a closer line card down to one item.
16) The door is a low traffic interior office door. Is there a lighter closer than the DORMA 8616?
Yes. The 8616 is built heavy duty for 10,000,000 cycles, which is more closer than a low traffic office door needs. The BEST SL6000 Series is Grade 1 light duty with adjustable spring sizes, the Arrow DCN325 is a Grade 1 light duty surface closer with a regular/parallel tri-pack arm and adjustable spring size 1-6, and the Norton Rixson 160 Series is a Grade 1 light duty closer for light commercial use with an adjustable spring. The LCN 1250 Series is light duty in sizes 1-5 with all-weather fluid and is ADA compliant.
17) What is the difference between the DORMA 8616 and a medium duty closer like the Sargent 1131 or Norton 8501A?
The DORMA 8616 is classified heavy duty and rated for 10,000,000 cycles at Grade 1. The Sargent 1131 is a Grade 1 medium duty adjustable surface closer aimed at medium traffic commercial applications, and the Norton Rixson 8501A is a Grade 1 medium duty tri-mount surface closer with an adjustable size 1-6 spring. All three are Grade 1; the split is duty classification and the traffic level each is positioned for. The BEST HD7000 Series sits in the same medium duty Grade 1 band.
18) Which other tri-pack non-hold open closers cover the same size 1-6 range as the DORMA 8616?
The 8616 is non-handed with an adjustable size 1 to 6 spring and ships as a tri-pack. Peers in the same tri-packed non-hold open arm configuration include the Accentra 2701 Series with adjustable spring sizes 1-6, the Design Hardware 116 Series and 416 Series, both heavy duty tri-packed non-hold open, and the Design Hardware 316 Series in medium to heavy duty. The Imperial USA TC4300 Series is a heavy duty size 1-6 ADA closer, and the Arrow DCN325 covers size 1-6 with a regular/parallel tri-pack arm.
19) Is the Arrow DCN500DP drop plate a substitute for the DORMA 8616?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer. The 8616 is a complete surface mounted door closer supplied with sex nuts for a 1-3/4 inch door and an adjustable parallel arm with parallel arm bracket. Similarly, the Stanley 327 and 341 are wardrobe pivots and the Stanley 57-0100 is a box of steel machine screws for architectural hinges, none of which control a door's closing.
20) Which closer should I use on an aluminum storefront entrance instead of the DORMA 8616?
The 8616 suits hollow metal, aluminum, and wood doors used in commercial construction. For a storefront specifically, the Norton Rixson 1600 Series in the 1600BC configuration is a Grade 1 heavy duty aluminum storefront door closer with tri-style mounting, and the Norton Rixson 1601P is a Grade 1 medium duty tri-mount surface closer with 180 degree swing.
21) If I am standardizing a facility on one Grade 1 tri-mount closer, which peers give me the same regular, parallel and top jamb flexibility as the DORMA 8616?
The 8616 is non-handed and ships as a tri-pack, so one part number covers the mounting options across a building. Peers with the same tri-mount flexibility include the Dexter DCH4000, DCL2000 and DCM1000 Series, all Grade 1 surface closers for regular, parallel or top jamb mounting, plus the Dexter DCH1000 Series with full cover. The Norton Rixson 8501A is a Grade 1 tri-mount closer with an adjustable size 1-6 spring, and the Calibre CA9901 is a Grade 1 tri-pack arm closer in size 2-5.
22) What finishes does the DORMA 8616 closer come in to match my other door hardware?
Six painted finishes: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze, and 696 satin brass. Those are BHMA finish numbers, so 689 and 690 will line up with the aluminum and dark bronze on most exit devices and hinges already hanging in a commercial building. Every finish carries the same AO8P tri-pack arm.
23) Is the DORMA 8616 rated for commercial use or is it a residential closer?
Commercial, and specifically heavy duty commercial. The 8600 Series is built for hollow metal, aluminum, and wood doors in commercial construction, carries ANSI/BHMA Grade 1 certification, and is tested to 10,000,000 cycles. For a residential or light retail door where none of that is needed, a Grade 2 hydraulic like the Cal-Royal 400 Series is the lighter option.
24) The DORMA 8616 has an aluminum body. Which comparable closers use cast iron?
The 8616 body substrate is aluminum. If the job calls for cast iron, the Sargent 281 Powerglide is a cast iron heavy duty Grade 1 surface closer and the LCN 1261 is a cast iron closer with adjustable spring sizes 1-5 in light to medium duty. Among cast aluminum peers, the Falcon SC71A is heavy duty Grade 1, the Falcon SC81A medium duty Grade 1, and the LCN 1450 is a medium duty cast aluminum closer with spring sizes 1-6.
25) The DORMA 8616 comes with a slim cover as standard. Which comparable closers include a full cover?
The 8616 offers slim plastic, full plastic, and full metal cover options. Among peers, the Dexter DCH1000 Series is a Grade 1 tri-mount surface closer supplied with a full cover, and the Design Hardware 316 Series is supplied with a cover. The Arrow DCN314 and DCN325 are both listed less cover, so a cover has to be added separately on those.
