Design Hardware 416 Friction Hold Open Arm

No. The 416 friction hold open arm is for non-fire-rated openings only. It holds the door open with a friction fitting under the nut, and a friction hold open is not permitted on a fire door, where the leaf has to be free to close and latch. If the opening is fire rated, you need a closer arm without a mechanical hold open, or a hold open tied into the fire alarm.

The parallel arm bracket comes with it. The 416 arm covers regular, top jamb, and parallel arm mounting, and the PA bracket is included, so one part number handles all three mountings without ordering the shoe separately.

Just the arm. The 416 is a replacement closer arm assembly with the parallel arm bracket, not a closer body. If your closer body is leaking or the spring is shot, the arm alone will not fix it.

The 416 is a Design Hardware 416 Series part and should be used on the matching Design Hardware closer. Closer arms are not interchangeable across manufacturers. For Corbin Russwin closers, the 688F77 regular arm with hold-open is the equivalent part, and the 688F95 regular arm covers regular and top jamb mounting without the hold open function.

No. A drop plate such as the Corbin Russwin 188F65, for the DC3220 with full cover, or the Corbin Russwin 597F58, for the DC3210 with full cover, is a mounting plate that lowers the closer body onto a narrow top rail or frame face - both are listed for 1-3/4 inch door thickness. It does not connect the closer to the door or jamb and has no hold open function. The Design Hardware 416 friction hold open arm is the linkage itself, with a friction fitting under the nut that holds the door at multiple open positions. An opening with a narrow top rail may need both parts: a plate to mount the closer and an arm to drive the door.

The Corbin Russwin 688F77 is a regular arm with hold-open for a door closer, which is the same job the Design Hardware 416 friction hold open arm does - holding the door open in non-fire-rated openings. The 416 uses a friction type fitting under the nut that allows multiple hold open positions, and it ships non-handed with a parallel arm bracket so it covers regular, top jamb and parallel arm mounting. The 688F77 is described as a regular arm with hold-open. Arms are matched to the closer body they mount on, so confirm the arm you order belongs to the closer series already on the door.

Use a non-hold-open arm. The Corbin Russwin 688F95 is a regular arm for regular and top jamb mounting with no hold-open feature, so the door closes every time. The Design Hardware 416 friction hold open arm is built to hold the door open, using a friction fitting under the nut for multiple hold open positions, and it is intended for non-fire-rated applications only. On a fire-rated opening the door must self-close, so the friction hold open arm is not the part to specify there.

No handing to specify. The 416 arm is non-handed, so the same part goes on a left hand or right hand door. For a property manager stocking spares across a building, that means one arm on the shelf covers every swing.

The 416 uses a friction fitting under the nut rather than a fixed detent, so the door can be held at multiple positions instead of one preset angle. Tightening or loosening that nut adjusts how much resistance the arm applies. Detent style arms lock at a single stated degree; a friction arm is the choice when you want the door parked wherever the job needs it that day.

There are two arm length positions on the 416, which is how it takes different jamb depths without a special order part. Set the forearm to the longer position for a deeper reveal and the shorter one where the frame sits close to the door face.

The 416 is rated standard duty, which suits interior and moderate traffic openings. For a main entrance taking constant use, or an exterior door catching wind load, a heavier duty arm is the better call.

Often not. The Design Hardware 416 friction hold open arm has two arm length positions to suit different jamb depths, and it is non-handed, so one part number covers left and right hand doors. The Corbin Russwin 688F95 is offered as a regular arm for regular and top jamb mounting, and the Corbin Russwin 688F77 as a regular arm with hold-open. Standardizing on the 416 across a building means one arm carried for regular, top jamb and parallel arm openings, with the parallel arm bracket included.

The Design Hardware 416 friction hold open arm is a standard duty part and comes in painted aluminum, dark bronze painted and gold, so it can be matched to the closer body and frame already on the opening. The Corbin Russwin 688F77 regular arm with hold-open is the comparable hold-open arm on that line. Both are complete closer arms rather than mounting accessories, so the decision comes down to which closer body is on the door and which finish the rest of the openings carry.

Three: aluminum painted, dark bronze painted, and gold. The finish is paint, not plated, so match it to the closer body already on the opening rather than to the lockset.
