Design Hardware 316/116 HD-HO Heavy-Duty Hold Open Arm with Dead Stop

Parallel arm only. The HD-HO is built to mount on the push side with the closer body on the door and the shoe on the frame soffit. If your closer is set up regular arm (pull side) or top jamb, this arm will not go on it. Corbin Russwin's 688F77 regular arm with hold-open is a regular arm style part for comparison.

It is a replacement arm for Design Hardware 116 and 316 Series closers. It is not a universal arm, so it should not be mixed onto another manufacturer's closer body.

It includes a removable auxiliary stop, so the arm itself dead-stops the door at the point you set it. That saves adding a wall or floor stop in a corridor where one would be a trip hazard or would not reach. Because the stop is removable, you can run the arm as hold open only if the opening already has a stop.

No. The Design Hardware 316/116 HD-HO is intended to hold doors open in non UL fire rated applications, so it should not be specified on a fire door assembly, where a mechanical hold open defeats the self-closing requirement. If you are working a fire-rated opening, you need a closer arm without a mechanical hold open; for example the Corbin Russwin 688F95 is a regular arm with no hold-open function. Match the arm to the closer body and mounting you already have.

The Design Hardware 316/116 HD-HO heavy-duty hold open arm with dead stop is parallel arm mounting only, so it will not serve a regular arm installation. For a regular arm mounted closer that still needs a hold open function, the Corbin Russwin 688F77 is a complete closer arm in a regular arm with hold-open configuration. Both give you hold open, but the geometry is different: the HD-HO pushes from the parallel arm side of the door, while the 688F77 is a pull-side regular arm assembly. Confirm which mounting the existing closer uses before ordering either.

No handing to specify. The HD-HO arm is non-handed, so one part covers both left and right hand doors. You only pick the finish.

That is what it is built for. The arm is forged solid steel and rated heavy duty for high use and abuse areas, which is the usual failure point on parallel arm closers where people push doors past the stop.

No. Machine, wood, and self-tapping machine screws come with the HD-HO arm, so it covers hollow metal frames, wood, and aluminum without a second trip.

No. A reveal or soffit clearance problem is solved with a drop plate or bracket, not by swapping the arm. Corbin Russwin lists drop plates such as the 188F65 and 597F58 for 1-3/4 inch doors on its DC3000 series closers. Match the plate to your own closer brand and model.

An arm swap may not solve a clearance problem. The Design Hardware 316/116 HD-HO is an arm assembly and changes hold open and stop behavior, not the height at which the closer body sits. When the closer body needs to be dropped below the frame face to clear a narrow top rail or a stop condition, the part is a drop plate, such as the Corbin Russwin 188F65 or the Corbin Russwin 597F58, both listed for 1-3/4 inch door thickness. A drop plate and an arm solve different problems and are often ordered together.

No, they are different parts. The Design Hardware 316/116 HD-HO is a forged solid steel arm that provides the hold open and dead stop function on a parallel arm closer. A drop plate such as the Corbin Russwin 188F65 or the Corbin Russwin 597F58 is a mounting bracket that repositions the closer body on the door or frame; both are specified for 1-3/4 inch doors and neither provides any hold open function. If the door is not staying open, you need the arm; if the closer body will not mount where it needs to, you need the plate.

The Design Hardware 316/116 HD-HO is built for that condition: forged solid steel construction rated heavy duty and described for high use and abuse areas, with a T-turn hold open and a removable auxiliary stop that takes the overswing load off the closer body. It is non-handed, so one part covers both left and right openings in a corridor run. A standard-duty hold open arm such as the Corbin Russwin 688F77 regular arm with hold-open serves normal traffic openings; the difference for your corridor is the construction and the dead stop, not the hold open itself.

Three: aluminum painted, dark bronze painted, and gold. Pick the one matching the closer bodies already on the building so a single replaced arm does not stand out against the rest of the openings.

You open the door to the hold open point and turn the T-handle on the arm to set it; turn it back to release and the closer takes over normally. It is a manual, per-use function, not a detent that grabs every time the door swings, so a door left unturned closes like any other.
