Stanley Security Grade 1 Surface Closer, Size 2-6, Standard Hold Open

Yes. The D4550 heavy duty surface closer mounts three ways: hinge (pull side), top jamb (push side), and parallel arm (push side). That covers the usual problem of a door that swings out into a corridor where you cannot put the closer body on the pull side, so you flip to parallel arm and mount the body on the door face with the arm to the frame soffit.

The D4550 is listed as ADA compliant, and the adjustable spring range of size 2 through 6 is what makes that work in practice: you dial the spring down for an interior accessible opening and up for a heavy exterior door. Same closer body either way, so you can standardize one part number across a building and adjust per opening.

This one is the standard hold open version. The arm holds the door open at the set point and releases when you pull the door past it. If you need a unit that always self-closes, look at a non hold open arm instead, such as the Accentra 2701 Series or the Design Hardware 416 Series, both listed with tri-packed non-hold open arms. Note that hold open arms are generally not used on fire rated openings.

The Stanley D-455 is a Grade 1 heavy duty surface closer covering spring sizes 2 through 6. Closest peers by duty class and size range are the BEST EHD9000 Series, an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6, and the Sargent 1431 Powerglide, a Grade 1 heavy duty surface closer with adjustable spring power. The Falcon SC71A Series is also a Grade 1 heavy duty surface-mount closer. Any of the three lands in the same heavy duty Grade 1 institutional class as the D-455.

The Stanley D-455 is built for institutional applications with an R-14 silicon aluminum alloy cylinder body, which is more closer than a low-traffic interior office door usually needs. For hold open on a lighter opening, 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. Both give you the hold open function in a lighter-duty package.

They are not in the same duty class. The Stanley D-455 is Stanley's best performing heavy duty closer, built for institutional openings. The LCN 1261 in the 1260 Series is a light to medium duty closer with adjustable spring sizes 1-5. If you want an LCN in the heavy duty class, the LCN 1460T is a heavy duty surface-mounted Grade 1 commercial closer with a powder coat finish, which also matches the powder coat finish type on the D-455.

The Stanley D-455 uses standard and heavy-duty arm configurations on a surface-mounted body. For a track application, 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, and the Dorma 8916-JT is a Grade 1 heavy duty closer with a jamb track, frame face mounting on the pull side and adjustable size 1-6. Both keep the pull side mounting orientation of the D-455.

The Stanley D-455 configuration covers standard hold open. For the same heavy duty class without hold open, the Design Hardware 116 Series and 416 Series are both heavy duty closers with tri-packed non-hold open arms, and the Dormakaba 8616 AF86P is a Grade 1 heavy duty closer with a flat arm non-hold open tri-pack. The Design Hardware 316 Series is the same non-hold open arm in a medium to heavy duty body with a cover.

That is what it was built for. The D4550 is Stanley's best performing heavy duty closer, with a cylinder body of R-14 silicon aluminum alloy for institutional use, and it is rated Grade 1. Spring range 2 through 6 gives you the power for a wide or heavy exterior leaf. It is a commercial-duty unit, not a residential one.

Yes. The D4550 uses all-weather hydraulic fluid, so closing speed stays consistent through temperature swings instead of slowing to a crawl in cold weather and slamming in the heat. The body carries a powder coat finish, which is the right choice for an exterior opening.

It sits in the same class as the BEST HD8000 and EHD9000 Series, the Falcon SC71A, the Sargent 1431 Powerglide, and the LCN 1460T, all of which we list as Grade 1 heavy duty surface mounted closers. The practical difference is arm and mounting options and body material: the D4550 body is R-14 silicon aluminum alloy, while the Sargent 281 is a cast iron heavy duty body. If your spec calls out a lighter unit, the Falcon SC81A is medium duty and the Arrow DC314 is light duty.

For lighter openings with a hold open arm, the Accentra 51 Series covers spring sizes 1 through 6 with a tri-packed hold open arm, and the Orca Hardware BHDC1958 HO/PA is a hold open unit with a parallel bracket for 1-3/4 inch doors. The Stanley D4550 is the heavy duty institutional choice with a size 2 through 6 range; the other two are the option when the opening does not demand that.

It depends on the opening, not the closer. Narrow top rails, blade stops, and flush panel frames all need an adapter regardless of brand. Common parts for that kind of situation include parallel arm mounting shoes, auxiliary shoes for top rails, blade stop spacers, and flush panel adaptors. Measure the top rail height and the reveal at the frame before you order, since that is what decides whether a plain tri-mount installation works.

The Stanley D-455 mounts hinge/pull side, top jamb on the push side, or parallel arm on the push side from one body. Peers with the same tri-mount flexibility include the Dexter DCH1000 Series, a Grade 1 surface closer that mounts regular, parallel or top jamb, the Norton Rixson 8501A, a Grade 1 tri-mount closer with adjustable size 1-6 spring, and the Arrow DCN325, a Grade 1 surface closer with regular/parallel arm tri-pack and adjustable spring size 1-6.

Stepping down from the D-455's heavy duty class, the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, and the Norton Rixson 160 Series is a Grade 1 light commercial closer with an adjustable spring. In the middle, the BEST HD7000 Series is a Grade 1 medium duty closer with adjustable spring power and backcheck control. All three are Grade 1 like the D-455 but carry a lighter duty rating.

They sit in different certification tiers. The Stanley D-455 is a Grade 1 heavy duty closer for institutional applications. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If you are staying with Cal-Royal and need Grade 1, the 700S Series is a Grade 1 dual valve sized closer with an adjustable tube arm, and the N900PBF is a Grade 1 barrier free hydraulic surface closer.

The Stanley D-455 is ADA compliant. Peers carrying ADA in their specification include the Imperial USA TC4300 Series, a Grade 1 heavy duty size 1-6 ADA closer, the Calibre CA9901, a Grade 1 tri-pack arm size 2-5 ADA surface mount closer, and the Calibre CA4001, a Grade 1 adjustable spring tension ADA hydraulic closer. The TC4300 is the nearest match on duty class to the D-455.

They carry the same Grade 1 certification but not the same duty class. The Arrow DC314 is a Grade 1 surface closer rated light duty, and the DCN314 is a light duty tri-pack closer with adjustable spring size 1-4, which stops short of the size 6 top end the Stanley D-455 covers. For a heavy duty Grade 1 alternate, the BEST HD8000 Series or the Falcon SC71A Series are closer matches to the D-455.

Delayed action is a different arm function from the standard hold open on the Stanley D-455. 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 regular arm with parallel bracket in the 2011 series. Both use a tri-packed non-hold open arm, so the door will not stay open on its own.

The Stanley D-455 is a commercial heavy duty closer for institutional applications and mounts hinge, top jamb, or parallel arm. For a narrow-stile aluminum storefront specifically, the Norton Rixson 1600 Series aluminum storefront closer with tri-style mounting is purpose-named for that opening and is Grade 1 heavy duty. The Norton Rixson 1601P is the same 1600 Series in a Grade 1 medium duty tri-mount version with 180 degree swing.

The Stanley D-455 uses an iron substrate. Grade 1 peers built on aluminum bodies include the Falcon SC81A Series, a medium duty cast aluminum surface-mount closer, the Falcon SC61A Series, a light to medium duty cast aluminum closer, and the Sargent 1331, a medium duty closer with a universal aluminum body. All three step down from heavy duty to medium duty relative to the D-455.

The Stanley D-455 body is finished in powder coat. 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 a medium to heavy duty closer supplied with a cover. By contrast, the Arrow DCN325 and DCN314 are Grade 1 surface closers supplied less cover, so plan on ordering a cover separately with those.
