Accentra (Yale) 400-1 689 Regular Arm Assembly

The Accentra (Yale) 400-1 689 is a regular arm assembly for the Yale 51, 3000, and 4400 Series door closers, in 689 aluminum finish. The 400-1 is a non-hold-open arm, meaning the door returns to the fully closed position on every cycle without a hold-open engagement point. Also referenced in parts ordering and distributor systems as ai41689 and 166968-001, this arm assembly is an aluminum replacement or original arm component for these three closer series. SKU: 400-1 689.

What a regular arm assembly does on a door closer and when the 400-1 is the correct arm

A door closer arm assembly connects the closer body to the door frame, controls the geometry of the closing arc, and determines the hold-open capability of the installation. The 400-1 is the regular standard arm format for the 51, 3000, and 4400 Series closers. "Regular arm" refers to the standard surface-mounted arm configuration, as opposed to a parallel arm, which mounts differently relative to the door frame and is used when the closer must be installed on the push side of the door rather than the pull side.

The 400-1 non-hold-open arm does not include a position where the door can be engaged and held open. The spring returns the door to fully closed on every cycle. This is the correct arm for fire-rated door assemblies where hold-open is not permitted, for egress doors where automatic closing is required, and for any installation where the closer specification or applicable code requires non-hold-open operation at all times. For door closers from the Accentra line that use this arm, browse the Accentra door closers catalog. For all door closer options across brands, the door closers section covers the full range.

Which Yale and Accentra closer series the 400-1 arm assembly fits

The 400-1 689 is compatible with the Yale and Accentra 51 Series, 3000 Series, and 4400 Series door closers. These three series share the same arm mounting geometry, allowing the 400-1 to serve as a replacement arm when the original arm is damaged or as part of a full closer assembly replacement. Before ordering the 400-1 as a replacement, confirm the existing closer body is one of these three series by checking the model designation on the closer body itself.

The arm assembly is not cross-compatible with other Yale or Accentra closer series outside the 51, 3000, and 4400 families. Using an arm assembly from a different series will result in incorrect arm geometry, which causes the door to close at the wrong angle and can damage the closer body over time. The catalog reference for the 4400 Series can be confirmed in the ASSA ABLOY Accentra 4400 Series Door Closers catalog available on the product page. For the 1111BF hold-open door closer with its own arm assembly, the Accentra Yale 1111BF door closer is also stocked.

Finish, material, and ordering details for the 400-1 689 arm assembly

The 400-1 is supplied in 689 aluminum finish, which is the standard aluminum finish that coordinates with the 689 aluminum closer body on the 51, 3000, and 4400 Series installations. The arm body is aluminum, consistent with the closer body material on these series. Confirm the existing closer is the 689 finish before ordering to ensure finish continuity across the arm and body.
