Stanley Security Drop Plate for D1610 Series

A drop plate is a flat mounting bracket that lowers the closer body so it can be fastened to a door or frame that doesn't have enough flat surface for the closer shoe or body. The Stanley Security drop plate is made for the D1610 series surface mounted closer. You need one when the top rail of the door or the frame face is too narrow for the closer footprint, which is common on narrow top rail aluminum and hollow metal openings.

No. It's cut and drilled for the Stanley Security D1610 series body, so the hole pattern matches that closer and not another manufacturer's. If you're working with a different closer, order the plate made for it. For example, Arrow publishes its own DCN500DP parallel drop plate for the DCN500 closer.

A drop plate lowers the closer body so it fits a narrow top rail while keeping the existing closer. The Stanley Security drop plate does that for a D1610 and supports the same surface mounting positions the closer uses - hinge (pull) side, top jamb (push) side and parallel arm (push) side. If you would rather change the closer, a track-arm unit such as the Corbin Russwin DC5230, a Grade 1 surface closer with a slide track arm standard for pull side mounting, is the other route to a tight head condition.

The D1610 closer it serves is a tri-mount unit: hinge (pull side) surface mount, top jamb mount on the push side, and parallel arm mount on the push side. The drop plate is used in the position your opening requires, with hinge/pull side being the primary mounting location listed for it.

It's iron with a powder coat finish, so it's a structural bracket rather than a trim cover. The D1610 closer it mounts uses all-weather fluid, which is what lets that closer run on exterior openings through temperature swings.

The Stanley Security drop plate is listed ADA compliant and is intended for commercial openings, so mounting the closer on it does not take the opening out of compliance on the hardware side; the closing force adjustment still lives in the closer. Closers commonly specified for barrier free work include the Cal-Royal 500S, a Grade 1 barrier free closer with adjustable back-check, and the Cal-Royal N900PBF 900 Series barrier free Grade 1 hydraulic closer.

The drop plate is a mounting accessory, not a closer - it carries no hydraulics and no spring. If the closer itself is being replaced, comparable surface mounted units include the LCN 1261, a light to medium duty 1260 Series closer with adjustable spring sizes 1-5, and the Sargent 1431 Powerglide, a Grade 1 heavy duty closer with adjustable spring power. The Stanley plate is finished in 695 dark bronze painted powder coat if you are matching an existing bronze closer.

One finish only: 695 dark bronze, applied as a powder coat. If the closer body on your opening is aluminum or brass toned, the plate will not match, so plan on painting it or choosing a closer finish that pairs with dark bronze.

Plenty of tri-mount surface closers cover the same openings. The LCN 1261 is a light to medium duty cast iron unit in the 1260 series, the Norton Rixson 1601P is a Grade 1 medium duty tri-mount with 180 degree swing, and the BEST HD8000 is a Grade 1 heavy duty option for higher traffic. Choose by duty level for the traffic on that door.

The Stanley Security drop plate supports the same three surface positions a tri-mount closer uses: hinge side pull, top jamb push, and parallel arm push. If the standard itself is being set, tri-mount closers in the same class include the Norton Rixson 1601P, a Grade 1 medium duty 1600 Series closer with tri-mount design and 180 degree swing, and the Dexter DCH1000, a Grade 1 surface closer with regular, parallel or top jamb mounting and full cover. Each of those uses its own brand's drop plate rather than the Stanley part.
