Stanley Security A45-501L - Long Rod Arm Standard, Top Jamb

The A45-501L is the long rod arm standard, top jamb configuration within the Stanley D-455 surface mounted closer family. It is a surface mounted commercial closer setup, and the long rod arm is what lets it reach across a deeper reveal at a top jamb opening than a standard-length rod would.

Yes. Three mounting positions are supported: hinge (pull side) surface mount, top jamb mount on the push side, and parallel arm mount on the push side. That covers most openings without changing product. The default configuration is pull side, so if the door swings away from you into a corridor or stairwell, specify the top jamb or parallel arm setup on the order.

The D-455 closer is ADA compliant, so it can be adjusted to the reduced opening force an accessible interior door requires. On any barrier free opening you still set spring power at install to suit the door and check the force at the door face after adjustment.

That is exactly what the long rod arm is for. On a top jamb mount the closer body sits on the frame face and the arm has to span back to the door; where the reveal is deep, a standard-length rod runs out of travel and the long rod version is the fix. Measure the reveal, the distance from the door face back to the frame face, before ordering, because a long arm on a shallow reveal is just as wrong as a short one on a deep reveal.

The A45-501L is a commercial surface closer with all-weather fluid. For an entrance that takes constant use, the BEST EHD9000 Series is an extra heavy-duty surface closer with Grade 1 certification and adjustable spring sizes 1-6, and the Sargent 1431 Powerglide is a heavy-duty Grade 1 surface closer with adjustable spring power. The Falcon SC71A is another Grade 1 heavy-duty surface-mount option. All three are rated heavy duty where the A45-501L is specified as a commercial unit.

The A45-501L is a surface mounted commercial closer that mounts hinge side pull, top jamb push, or parallel arm push. The Dexter DCH1000 is a Grade 1 surface closer offered as a tri mount unit covering regular, parallel and top jamb mounting, with a full cover. The Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring. Both cover the same three mounting positions, so either can take a top jamb opening the A45-501L was specified for.

The A45-501L is an ADA compliant commercial closer with a standard long rod arm. Where the opening needs delayed action so a slower user can clear the door, 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 arrangement in the BHDC2011 series. Both are supplied as tri-packed non-hold open arm units.

It uses all-weather hydraulic fluid, which is what keeps closing speed consistent when the temperature swings. A closer with standard fluid thickens in cold and the door starts slamming in summer and dragging in winter; all-weather fluid is why this one holds its adjustment on an exterior entrance or an unheated stairwell.

Top jamb puts the closer body on the frame face above the door with the arm reaching down to the door, which is the usual answer on aluminum storefront where the door stile is too narrow to carry the closer body. Parallel arm puts the body on the door and tucks the arm back flat against the frame, which is what you want in a corridor where a projecting arm would get hit. The A45-501L is set up as a long rod arm top jamb configuration, and the same closer also supports parallel arm and pull side hinge mounting.

No mortising is required. It is a surface mount closer, so it fastens to the face of the door or frame and only needs drilling and tapping to the template. That is the practical difference from a concealed overhead or floor closer, which needs the frame or the floor prepped and is generally a new-door or full-frame-replacement decision.

A standard arm closer uses a jointed arm that projects out from the door, which is what the A45-501L long rod arm does. The Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm, pull side mounting, for 1-3/4 inch doors; a track arm rides in a channel and stays tight to the door, which is what you specify where the projecting arm is a vandalism or clearance problem, such as a detention or psychiatric setting or a tight corridor.

For interior doors that see lighter traffic, the LCN 1250 Series is a light-duty surface closer with sizes 1-5, all-weather fluid and ADA compliance, matching the A45-501L on both fluid type and ADA compliance. The BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, and the Arrow DC314 is a Grade 1 light duty surface closer. The Falcon SC91A is a light duty cast aluminum closer at Grade 3.

Several Grade 1 surface mounted closers cover the same commercial openings. The Corbin Russwin DC3200 is a Grade 1 surface closer with a regular arm for doors 1-3/4 inch thick, the Cal-Royal 700S is a Grade 1 dual valve sized closer with an adjustable tube arm, and the Calibre CA9901 is a Grade 1 tri-pack arm ADA surface mount closer in sizes 2-5. The Dormakaba 7414 is a Grade 1 medium duty closer in sizes 1-4.

The A45-501L pairs with a long rod arm for top jamb mounting where the standard arm will not make the reach. Comparable long reach and track alternatives include the Dorma 8916-JT, a Grade 1 heavy duty jamb track closer for frame face pull side mounting with a flat non-hold open arm and adjustable size 1-6, and the Corbin Russwin DC5230, a Grade 1 surface closer with a slide track arm standard for pull side mounting. A track arm handles reveal geometry differently than a rod and shoe arm.

No. The A45-501L is a complete surface mounted door closer. The Arrow DCN500DP is a parallel drop plate for the DCN500 closer, a mounting accessory that adapts a closer to the door face rather than a closer itself. If you need a closer body, the Arrow DCN314 or DCN325 are Grade 1 surface closers with regular and parallel tri-pack arms in adjustable spring sizes 1-4 and 1-6 respectively.

For a facility standard, closers with a broad adjustable spring range let one part number cover interior and exterior leaves. The Accentra 2701 Series is an architectural closer with tri-pack mounting and adjustable spring sizes 1-6, the Imperial USA TC4300 is a Grade 1 heavy duty ADA closer in sizes 1-6, and the BEST HD8000 Series is a Grade 1 heavy duty surface closer. The Norton Rixson 8501A also covers sizes 1-6 with tri-mount hardware.

The A45-501L is a surface mounted commercial closer that can mount top jamb on the push side, a common storefront arrangement. The Norton Rixson 1600BC Series is a heavy duty Grade 1 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. Both cover the storefront application with mounting flexibility comparable to the A45-501L.

They are not equivalent on certification. The A45-501L is a commercial surface mounted closer. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer, a different ANSI grade than Grade 1 units such as the Cal-Royal 500S barrier free closer with adjustable back-check or the Cal-Royal N900PBF barrier free hydraulic closer. For a facility spec calling for Grade 1, the 500S or N900PBF match that requirement where the 400 Series does not.

695 dark bronze painted is the finish, which is the standard match for bronze anodized aluminum storefront and dark bronze hollow metal frames. If the rest of the openings in the building are aluminum or brushed, this one will read noticeably darker.

The A45-501L is a surface mounted commercial closer using all-weather fluid, mountable hinge side, top jamb or parallel arm. The LCN 1261 is a surface mounted closer of cast iron construction, light to medium duty, with adjustable spring sizes 1-5. The Sargent 281 Powerglide is a cast iron surface closer with heavy-duty construction at Grade 1. Cast iron bodies differ from cast aluminum bodies such as the Falcon SC81A, a Grade 1 medium duty cast aluminum surface closer.

For a finished appearance on a visible opening, the Design Hardware 316 Series is a medium to heavy duty closer supplied with a cover and a tri-packed non-hold open arm, and the Dexter DCH1000 is a Grade 1 tri mount surface closer with a full cover. By contrast the Arrow DCN314 and DCN325 are supplied less cover. All are surface mounted like the A45-501L.
