Stanley Security CO-53 – Frequently Asked Questions

1) Which Stanley CO-50 door closer size do I need for a 42 inch door?
The CO-50 hold-open closer is offered in three capacity options: 36 inch doors up to 145 lbs, 42 inch doors up to 190 lbs, and 60 inch doors up to 400 lbs. For a 42 inch leaf, take the 190 lb option. Match the door's actual weight too, not just the width - a 42 inch solid core or a lead-lined leaf can run past 190 lbs, and that is a 60 inch / 400 lb order instead. Spring power across the family covers sizes 1 through 6.
2) Is the Stanley CO-50 closer handed? I have left and right hand doors in the same building.
Non-handed. One CO-50 closer works on either hand of door, so a property manager standardizing across a floor orders one part number and stocks one spare rather than splitting the order by handing. Mounting is available on the pull side or the push side, which is where the install decision actually gets made.
3) Does the Stanley CO-50 closer meet ADA opening force requirements?
The CO-50 is certified to ANSI/BHMA A156.4 and to ANSI A117.1, the accessibility standard, and a barrier-free option is offered. Practically, ADA compliance on a closer is a function of how low you can set the spring power and still get the door latched, so on an interior barrier-free opening you specify the barrier-free build and set spring size at the low end of the 1 to 6 range. On an exterior door fighting wind or stack pressure you will need more power, and that is a trade-off the code official has to sign off on.
4) What is a heavy duty Grade 1 door closer with an adjustable size 1 through 6 spring that mounts on the face of the door instead of inside it?
The Stanley Security CO-5 is concealed in the door with a size 1 to 6 adjustable spring at Grade 1 heavy duty. If the opening needs the closer body on the surface instead, the BEST EHD9000 Series is an extra heavy-duty surface mounted closer with adjustable spring sizes 1-6 at Grade 1, and the Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring. Both put the body and arm in view; the CO-5 keeps them out of sight in the door leaf.
5) Is a slide track or jamb track closer the same thing as a concealed-in-door closer?
No. The Stanley Security CO-5 is concealed inside the door leaf itself. A track closer still has its body exposed and rides an arm in a track on the frame: the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting, and the Dorma 8916-JT is a Grade 1 jamb track closer for frame face mounting on the pull side, size 1-6 adjustable. Both change the look of the arm, not whether the body shows.
6) What surface closer is barrier free for an ADA opening if a concealed closer cannot be used?
The Stanley Security CO-5 includes a barrier-free option to meet ADA requirements and is listed to ANSI A117.1. Where the door leaf cannot take a concealed closer, the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF is a Grade 1 barrier free hydraulic surface closer, and the Calibre CA4001 is a Grade 1 hydraulic closer with adjustable spring tension for ADA. All three mount on the door face.
7) What is a comparable hold open door closer if the Stanley CO-50 is not the right fit?
For a hold-open arm specifically, the Accentra 51 Series carries a tri-packed hold open arm with size 1-6 spring, and the Orca BHDC1958HO/PA is a hold open closer with a parallel bracket rated for 1-3/4 inch doors. If the opening is heavy but does not need hold-open, the BEST EHD9000 Series is an extra heavy duty Grade 1 unit with adjustable spring sizes 1-6, and the Sargent 1431 Powerglide is a heavy duty Grade 1 alternative. Watch the difference: a tri-packed closer ships to mount regular, parallel, or top jamb, which is the flexible choice when the field conditions are not confirmed yet.
8) What fasteners come with the Stanley CO-50 closer, and do I need anything extra for a hollow metal door?
Wood and machine screws ship standard, and sex nuts plus self-reaming, self-tapping screws are standard as well. That covers the three cases a contractor actually hits: machine screws into tapped hollow metal, self-reaming screws where the frame or door is not pre-tapped, and sex nuts through a wood or mineral core door where you need to clamp from both faces. No separate fastener kit to add to the order.
9) Is the Stanley CO-50 heavy duty enough for a high traffic entrance?
Heavy duty, Grade 1, and rated commercial. Certification is to ANSI/BHMA A156.4, which is the door closer standard, and Grade 1 is the top tier of it. For an entrance where the door gets pulled all day, spec the closer with the back check valve so the door cannot be thrown into the wall, and delayed action if you have carts or people carrying loads through the opening.
10) What else should I specify when ordering a Stanley CO-50 closer besides the size?
Three decisions beyond the door width and weight option. First, spring power within the 1 to 6 range, driven by the opening: exterior and wide doors go high, ADA interior openings go low. Second, the premium valve package if you want delayed action, back check, or both. Third, the barrier-free build if the opening has to hit ANSI A117.1. Closing speed and latching speed are field adjustable on every unit, so those are set at install, not on the order form.
11) I have a light interior office door. Is the Stanley CO-50 overkill?
Probably, yes. The CO-50 is a heavy duty Grade 1 commercial closer, and the smallest capacity option still covers a 36 inch door up to 145 lbs. On a light interior door in a low traffic office, a light duty Grade 1 unit like the Arrow DC314 or the BEST SL6000 Series does the job, and the Falcon SC91A is a Grade 3 light duty option if the opening is not spec-driven. Where the CO-50 earns its place is a heavy leaf, an entrance, or a facility standardizing on one Grade 1 closer everywhere.
12) What door closer gives delayed action if the Stanley CO-5 will not fit the door?
The Stanley Security CO-5 offers delayed action and a back check valve among its premium performance options, concealed in the door. In a surface mounted closer, the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, and the Orca BHDC2011DA/PA is a delayed action closer in the same regular arm with parallel bracket configuration. Both are set up for 1-3/4 inch doors.
13) Does a tri-pack or tri-mount closer install the same way as the Stanley CO-5?
No, and it is a common mix-up. The Stanley Security CO-5 is concealed in the door and mounts pull side or push side. A tri-pack closer ships with the brackets to mount three ways on the door or frame face: the Arrow DCN325 is a Grade 1 surface closer, less cover, with regular and parallel arm tri-pack and adjustable spring size 1-6, the Dexter DCH1000 Series is a Grade 1 tri mount surface closer for regular, parallel or top jamb mounting with a full cover, and the Calibre CA9901 is a tri-pack arm size 2-5 ADA surface mount closer. Tri-pack describes surface mounting flexibility, not concealment.
14) What closer should be used on an aluminum storefront door instead of a concealed-in-door closer?
The Stanley Security CO-5 is concealed in the door leaf, which requires a leaf that can be prepped for it. For an aluminum storefront opening, the Norton Rixson 1600 Series aluminum storefront closer is a Grade 1 heavy duty unit with tri-style mounting, and the Corbin Russwin DC3200 is a Grade 1 regular arm surface closer for 1-3/4 inch doors. Both mount to the face of the stile or frame rather than inside the door.
15) Can the door slam or hold at the wrong angle be adjusted after the Stanley CO-50 is installed?
Closing speed and latching speed are both adjustable on the CO-50, so a door that slams into the frame or crawls the last few inches without latching is a valve adjustment, not a replacement. Hold-open angle is set by the arm so the door parks where you want it for deliveries or maintenance. If the complaint is the door swinging hard into an adjacent wall, that is what the back check valve option controls, and back check has to be specified at order time.
16) Which closers cover the same spring size range of 1 to 6 as the Stanley CO-5?
The Stanley Security CO-5 carries an adjustable closer size of 1 to 6. Surface mounted closers spanning the same range include the Accentra 51 Series with hold open, the Accentra 2701 with tri-pack mounting, the Arrow DCN325, the BEST EHD9000, the Norton Rixson 8501A, the Dorma 8916-JT, and the Imperial USA TC4300, a Grade 1 heavy duty size 1-6 ADA closer. A single-size or 1-4 unit such as the Arrow DCN314 or the Dormakaba 7414 will not reach the upper sizes.
