Spring Cushion Stop Add-On Kit for PDQ DS and DSHO Closer Arms
The PDQ SCS Series Spring Cushion Stop helps reduce wear and tear on the opening. As the door moves through backcheck to its maximum opening angle, the stop acts as a shock absorber and dampens the impact forces.
The unit is an add-on kit for PDQ DS and DSHO door closer arms. It can be ordered as an option on a new arm or installed on an existing DS or DSHO application using the arm's threaded bumper stop hole and one of the mounting screw holes.

PDQ 999032630 – Frequently Asked Questions
1) Will the PDQ SCS-1 spring cushion stop fit my existing door closer arm?
Only if it's a PDQ DS or DSHO arm with the cushioned bumper, in a PA (parallel arm) mount. The SCS-1 kit (part 999032) mounts to that arm using the arm's threaded bumper stop hole plus one of the existing mounting screw holes, so no new drilling on the arm. It will not fit a DS arm with the old style metal bumper, and it is not a standalone stop - a PDQ DS or DSHO arm has to be in place or purchased with it.
2) Do I need SCS-1 or SCS-2 for my door?
Spring size is matched to door size. SCS-1, PDQ part 999032, is for 3'0" x 8'0" wood or hollow metal doors and frames. For a 4'0" x 8'0" opening you want SCS-2, PDQ part 999033. Putting the 3'0" spring on a 4-foot wide leaf gives you the wrong spring rate for the door's mass.
3) Do I have to order the spring cushion stop handed for a left or right hand door?
No. The SCS-1 spring cushion stop is field reversible, so the same kit covers left hand and right hand doors and hand is set during installation. One part number covers both, which makes it easy to stock a few for a building with mixed swings.
4) What does a spring cushion stop actually do that a regular overhead stop doesn't?
It works as a shock absorber rather than a hard stop. As the door runs through backcheck toward its maximum opening angle, the SCS unit's spring dampens the impact forces instead of halting the leaf abruptly, which cuts wear on the closer arm, door and frame. A wall or floor stop or a rigid overhead stop takes the hit head on. PDQ also states the kit does not alter or decrease the strength of the DS/DSHO arm it mounts to.
5) Can I add the spring cushion stop later, or does it have to come with a new closer arm?
Either way. The SCS-1 can be specified as an option on a new PDQ DS or DSHO arm, or retrofitted to an arm already hanging on the door using the arm's threaded bumper stop hole and one mounting screw hole. That makes it a practical upgrade on openings where doors are getting slammed past backcheck.
6) Will the SCS-1 work on a wood door, or hollow metal only?
Both. PDQ rates SCS-1 for 3'0" x 8'0" wood or hollow metal doors and frames. The kit attaches to the closer arm rather than the door face, so the governing factor is the arm type (PDQ DS or DSHO, PA mount, cushioned bumper) and the door size, not the door material.
7) Is the PDQ spring cushion stop suitable for a high traffic exterior entrance?
It's built for commercial use and made from investment cast stainless steel for corrosion resistance and durability, which holds up on exterior and wet locations. The design is self aligning, so it keeps seating correctly through repeated cycles. It's commercial grade hardware, not a residential bumper.
8) What finishes does the PDQ 999032 spring cushion stop come in, and how do I order the right one?
Four: 605 Bright Brass (PVD), 613E Dark Oxidized Satin Bronze (PVD), 630 Satin Stainless Steel, and 693 Black. The finish code appends to the base number, so Bright Brass is 999032605 and Black is 999032693. Match the code to the closer arm already on the opening so the add-on doesn't stand out.
