Stanley Security CO-153 – Frequently Asked Questions

1) Which size CO-150 concealed closer do I need for a 48 inch wide door?
The Stanley CO-150 concealed closer is offered in three door capacities, and the 48 inch version handles doors weighing up to 260 pounds. The other two cover 36 inch doors up to 145 pounds and 60 inch doors up to 400 pounds. Match the size to the actual leaf width and weight, not just the opening, because an oversized spring on a light door makes it hard to pull and an undersized one will not close a heavy leaf against latch resistance. Spring power across the series is adjustable within sizes 1 through 6.
2) Do I have to order a left hand or right hand version of the Stanley CO-150 closer?
No handing to specify. The CO-150 is non-handed, so one unit covers left and right hand openings. It can be applied pull side or push side.
3) Can I use a concealed-in-frame closer on a fire rated door opening?
The CO-150 carries UL/cUL listing including UL10c and UL10b, the positive pressure and neutral pressure fire door test standards, so it is suitable for labeled fire door assemblies. Note that a hold open closer on a fire door must release on alarm, so for a fire rated opening the hold open function has to be handled by an electrified hold open arrangement rather than a mechanical detent that keeps the door open with no release. Confirm the specific hold open option against the opening's label requirements.
4) Does the Stanley CO-150 closer meet ADA opening force requirements?
Yes. The CO-150 is certified to ANSI/BHMA A156.4 for door closers and ANSI A117.1, the accessibility standard behind ADA opening force limits, and the unit is offered with a barrier free adjustment. Adjustable spring power is what gets you there: on an interior opening you can dial the spring down to meet the 5 pound maximum pull while still using the sweep and latch valves to control the close.
5) What is the difference between a concealed in frame closer and a surface mounted closer?
A concealed in frame closer like the Stanley CO-150 mounts inside the head of the frame with only the arm visible, which keeps the closer body out of reach of tampering and off the face of the door. A surface closer bolts to the door or frame face and is visible. The trade is access: a surface unit can be added to an existing opening and serviced without touching the frame, while the concealed unit requires a frame prepped for it, so it is a decision made at the frame order, not after the fact. If the frame is already installed and unprepped, a surface Grade 1 heavy duty unit such as the BEST EHD9000 Series or the Sargent 1431 Powerglide is the practical route.
6) What surface-mounted Grade 1 heavy duty closer can I use instead of the Stanley CO-155 when the frame has no room for a concealed unit?
The Stanley CO-155 mounts inside the door frame, so a frame without the required pocket rules it out. Surface-mounted heavy duty Grade 1 alternatives include the BEST EHD9000 Series extra heavy-duty closer with adjustable spring sizes 1 to 6, the BEST HD8000 Series heavy duty closer, the Falcon SC71A heavy-duty surface-mount closer, and the Sargent 1431 Powerglide heavy-duty surface closer with adjustable spring power. All four hang on the face of the door or frame rather than inside it, which means the body and arm stay visible but no frame preparation is needed.
7) Which closers also offer a hold-open arm like the Stanley CO-155?
The Stanley CO-155 includes a hold-open feature that lets the door stand open at a chosen angle. Among surface-mounted options, the Accentra 51 Series industrial closer is supplied with a tri-packed hold open arm and adjustable spring sizes 1 to 6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors. Both hold the door open through the arm at the face of the opening, where the CO-155 does it from inside the frame.
8) What mounting screws come with the Stanley CO-150 closer?
Wood and machine screws ship standard, and sex nuts plus self-reaming, self-tapping screws are standard as well. That covers hollow metal and wood frames and gives you through-bolting where the substrate will not hold a thread on its own. Fastener package aside, the frame still has to be prepped for a concealed unit.
9) What adjustments does the CO-150 concealed closer have once it is installed?
Closing speed, latch action, and delayed closing are all adjustable, and spring power covers sizes 1 through 6, so one unit can be tuned across a range of door widths rather than being fixed at one power. A back check valve is included to control the door in the open swing. In practice that means a property manager can retune the same closer if traffic patterns or wind loading on the entry change.
10) I want a hold open closer but my frames are not prepped for concealed. What else can I use?
Stay with a hold open arm on a surface unit. The Accentra 51 Series is a tri-packed hold open arm closer with adjustable spring sizes 1 through 6, which matches the CO-150's size range, and the Orca BHDC1958 hold open version is a tri-packed hold open arm closer for 1-3/4 inch doors. Both mount to the door or frame face, so no frame prep is required. What you give up against the concealed CO-150 is the hidden body and the tamper resistance that comes with it.
11) Can I mount the Stanley CO-150 on the push side of the door?
Yes, the CO-150 is listed for both pull side and push side mounting, and it is non-handed, so the same unit works either way. Push side application is common where the closer has to stay clear of the corridor or where the door swings out of a stairwell.
12) I need the same size 1 through 6 adjustment as the Stanley CO-155 but in a lower-cost surface closer. What are my options?
The Stanley CO-155 is adjustable across closer sizes 1 to 6. Surface-mounted closers covering the same spring range include the Arrow DCN325 Grade 1 closer with regular and parallel arm tri-pack and adjustable spring size 1 to 6, the Norton Rixson 8501A Grade 1 tri-mount closer with adjustable size 1 to 6 spring, the Accentra 2701 with adjustable spring sizes 1 to 6, the Imperial USA TC4300 Grade 1 heavy duty size 1 to 6 ADA closer, the LCN 1450 with spring sizes 1 to 6, and the Dorma 8916-JT Grade 1 closer adjustable size 1 to 6. The DCN325 ships less cover, and the 8916-JT uses a jamb track with frame face mounting on the pull side.
13) Is a slide track closer a substitute for the Stanley CO-155 on a door where I want a low-profile arm?
They solve the same visual problem differently. The Stanley CO-155 hides the entire closer inside the frame, so nothing but the arm connection shows. The Corbin Russwin DC5230 is a Grade 1 surface closer supplied standard with a slide track arm for pull side mounting on 1-3/4 inch doors, and the Dorma 8916-JT is a Grade 1 heavy duty closer with a jamb track and frame face mounting on the pull side. Both keep the arm tight to the door instead of projecting, but the closer body remains surface mounted and visible.
14) Which closers are similar to the Stanley CO-155 but do not hold the door open?
If you need the door to close every cycle, look at non-hold-open arms rather than the CO-155, which includes a hold-open feature. The Accentra 1101BF and Accentra 2701 both use a tri-packed non-hold open arm, the Design Hardware 116 and 416 Series heavy duty closers use a tri-packed non-hold open arm, and the Dorma 8916-JT uses a flat non-hold open arm. The Orca BHDC1958RA/PA is a non-hold open regular arm version of the same series as the hold open BHDC1958HO/PA, which is useful if you want the two behaviors matched across a building.
15) Does the Arrow DCN500DP drop plate work with the Stanley CO-155?
No. The Arrow DCN500DP is a parallel drop plate for the Arrow DCN500, not a closer and not a mounting accessory for a frame-concealed unit. The Stanley CO-155 installs inside the door frame and mounts pull side or push side without a surface drop plate. Drop plates belong with surface-mounted closers where the bracket needs to clear a stop or a narrow top rail.
16) What barrier-free or ADA closers match the Stanley CO-155 for an accessible entrance?
The Stanley CO-155 has a barrier-free design certified to ANSI A117.1 for ADA compliance. Comparable barrier-free surface closers include the Cal-Royal 500S Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free Grade 1 hydraulic closer, the Calibre CA9901 tri-pack arm size 2 to 5 ADA closer, the Calibre CA4001 with adjustable spring tension, and the Imperial USA TC4300 Grade 1 heavy duty size 1 to 6 ADA closer. The CO-155 differs in that it also carries adjustable delayed action and a back check valve as standard while hidden in the frame.
17) I want delayed action like the Stanley CO-155 has as standard. Which other closers offer it?
Delayed action holds the door open longer at the start of the closing cycle, which helps at accessible openings and carts. The Stanley CO-155 includes delayed action and a back check valve as standard. On the surface-mounted side, 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 Orca BHDC2011DA/PA is the same delayed action configuration in the BHDC2011 series. Both use a tri-packed non-hold open arm rather than a hold-open arm.
18) Is the Cal-Royal 400 Series an equivalent to the Stanley CO-155?
Not on certification level. The Stanley CO-155 is a Grade 1 heavy duty unit. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If the specification on the drawing calls for Grade 1, step up to something like the Cal-Royal 700S Grade 1 dual valve sized closer with adjustable tube arm or the Cal-Royal 500S Grade 1 barrier free closer instead.
19) What should I standardize on across a building if some openings can take the Stanley CO-155 and others cannot?
A common approach is to pair the frame-concealed Stanley CO-155 at feature entrances with a tri-mount surface closer elsewhere, since tri-mount units cover regular, parallel and top jamb applications from one part number. Options include the Dexter DCH1000 Grade 1 tri-mount closer with full cover, the Dexter DCM1000 and DCL2000 Grade 1 tri-mount closers, and the Norton Rixson 1601P Grade 1 tri-mount closer with 180 degree swing. The CO-155 itself is non-handed and mounts pull side or push side, so it does not need to be ordered by hand.
20) For a medium-traffic interior opening, what is a step down from the Stanley CO-155?
The Stanley CO-155 is a heavy duty Grade 1 unit built for high-traffic entrances. For medium traffic, medium duty Grade 1 surface closers include the Sargent 1131 for medium-traffic commercial applications, the Sargent 1331 with universal aluminum body, the BEST HD7000 Series with adjustable spring power and backcheck control, the Falcon SC81A medium duty cast aluminum closer, and the Dormakaba 7414 in size 1 to 4. The 7414 and the DORMA 7303 are both medium duty and offered in a painted finish.
