Stanley Security D-3550/D-4550 Hold Open Arm Standard, Top Jamb

Top jamb mounting on the push side is one of the supported configurations, along with hinge (pull side) surface mounting and parallel arm mounting on the push side. Which one you use depends on the opening: top jamb when the closer goes on the frame face above the door, parallel arm when you want the closer and arm tucked against the door face on the push side.

A hold open arm has an adjustable stop in the arm that lets the door stand open at a set degree until someone pulls it shut, then the closer controls it back. A non-hold-open arm closes the door every time. Pick hold open for openings where staff need the door propped during deliveries or moving, and non-hold-open for anything that has to self-close, like a fire-rated or smoke-barrier door.

It is a commercial-duty door control, and the D-455 closer package it belongs to is listed as ADA compliant. ADA compliance on a closer is about adjustable spring power and sweep timing, so on install set the spring size and closing speed to the opening force allowed for your door type rather than assuming it is right out of the box.

The closer uses all-weather hydraulic fluid, which holds its viscosity across temperature swings so the door does not slam in summer and drag in winter. That makes it workable on exterior entrances and unheated vestibules, not just interior corridors.

A few in the same class. The Accentra 51 Series ships tri-packed with a hold open arm and covers spring sizes 1 through 6. The Orca Hardware BHDC1958 hold open version comes with a parallel bracket and is listed for 1-3/4 inch doors. If you would rather have a delayed-action closer than a mechanical hold open, the Orca BHDC1958DA and BHDC2011DA are delayed action with a regular arm and parallel bracket.

For heavy traffic, look at the BEST EHD9000 Series, a Grade 1 extra heavy-duty surface closer with adjustable spring sizes 1 through 6, or the Sargent 1431 Powerglide, Grade 1 heavy duty with adjustable spring power. The Falcon SC71A is another Grade 1 heavy-duty surface closer. For medium traffic interior openings the Sargent 1131 or BEST HD7000 are the step down.

The Stanley Security D-3550/D-4550 arm covers hinge side, top jamb push side and parallel arm push side applications, all of which need mounting surface on the door or frame face. Where the frame face is the only usable surface, the Dorma 8916-JT is a Grade 1 jamb track closer with frame face mounting on the pull side. A slide track option is the Corbin Russwin DC5230, a Grade 1 surface closer with a slide track arm mounted on the pull side.

The Stanley Security D-3550/D-4550 arm is a commercial surface mount part rated ADA compliant and used with all-weather fluid closers, which suits exterior service. For a heavy duty closer body under it, heavy duty Grade 1 units include the BEST EHD9000 Series with spring sizes 1-6, the Sargent 1431 Powerglide, and the Falcon SC71A. The Norton Rixson 1600BC is a heavy duty Grade 1 closer built for aluminum storefront doors.

The Stanley Security D-3550/D-4550 arm is a commercial part intended for surface mounted closers. On low traffic interior doors, lighter duty closers include the LCN 1250 Series, a light duty surface closer with sizes 1-5 and all-weather fluid, the BEST SL6000 Series Grade 1 light duty closer, and the Arrow DC314 Grade 1 light duty surface closer.

Hold open parks the door; delayed action slows the close cycle so a slower user or a cart can clear the opening before the door starts to shut. The Stanley Security D-3550/D-4550 is a hold open arm. For delayed action, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket, both listed for 1-3/4 inch doors.

The Stanley Security D-3550/D-4550 arm supports hinge side pull, top jamb push and parallel arm push mounting, so one part covers several opening conditions. Closers with the same tri-mount flexibility include the Dexter DCH4000 and DCL2000 Series, both Grade 1 tri mount for regular, parallel or top jamb, the Norton Rixson 1601P Grade 1 tri-mount with 180 degree swing, and the Arrow DCN325, a Grade 1 regular/parallel arm tri-pack with adjustable spring size 1-6.

The Stanley Security D-3550/D-4550 arm is ADA compliant. Comparable barrier free and ADA closers include the Cal-Royal 500S, a Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free Grade 1 hydraulic closer, the Calibre CA4001 adjustable spring tension ADA closer, and the Imperial USA TC4300, a Grade 1 heavy duty ADA closer in sizes 1-6.

Two painted finishes: 689 aluminum painted and 695 dark bronze painted. 689 is the usual match for aluminum storefront and clear anodized frames, 695 for dark bronze frames and doors. If you are standardizing a building, pick the one already on the other closers so the arms match across the openings.

The Stanley Security D-3550/D-4550 arm comes in 689 aluminum painted and 695 dark bronze painted, the two most common architectural closer finishes. Among comparable closers, the Dorma 8916-JT is offered in 689 and the Dormakaba 8616 AF86P FC SNB1 is offered in 689 as well, so a mixed-brand building can still read as one finish. The DORMA 7303 Series is a painted finish medium duty closer.

For a parallel arm push side application on moderate traffic openings, medium duty Grade 1 closers include the Sargent 1131 and Sargent 1331, the BEST HD7000 Series with adjustable spring power and backcheck, and the Falcon SC81A cast aluminum closer. The Stanley Security D-3550/D-4550 arm itself is set up for parallel arm push side as one of its mounting options.
