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 999033630 – Frequently Asked Questions
1) Will the PDQ SCS-2 cushion stop fit my existing closer arm?
Only if it is a PDQ DS or DSHO arm with the cushioned bumper, parallel arm (PA) mount. It will not fit DS arms with the old style metal bumper, and it is not a universal accessory for other brands of closer arm. On a qualifying arm it mounts using the arm's existing threaded bumper stop hole plus one of the mounting screw holes, so no new drilling of the arm is involved.
2) Is the PDQ 999033 a complete door stop or do I need a closer arm too?
It is an add-on kit, not a standalone stop. The SCS-2 requires a PDQ DS or DSHO arm to mount to, either ordered as an option on a new arm or retrofitted to one already on the opening. If there is no DS or DSHO arm on the door, the kit has nothing to attach to and you would be looking at a wall or floor stop instead.
3) What does a spring cushion stop actually do that a backcheck does not?
It works at the end of the swing rather than through it. As the door passes backcheck and travels to its maximum opening angle, the SCS-2 spring and cushioned bumper absorb the shock and damp the impact forces, which takes the abuse off the arm, the door and the frame on wide, tall leaves. PDQ also states adding it does not alter or reduce the strength of the DS/DSHO arm.
4) Do I have to order the PDQ spring cushion stop handed for a left or right hand door?
No. Handing on the SCS-2 is determined in the field and the unit is reversible for both left hand and right hand doors, so one part number covers either swing. That makes it practical to stock a single kit for a building with openings swinging both ways.
5) Can I retrofit the PDQ SCS-2 to closers already installed, or does it only ship with new arms?
Either way. It can be ordered as an option on a new DS or DSHO arm, or installed in the field on an existing DS or DSHO application using the arm's threaded bumper stop hole and one mounting screw hole. The design is self aligning, which keeps field installation straightforward. The one limit is the bumper type, the arm must have the cushioned bumper, not the old style metal one.
6) What finishes does the PDQ SCS-2 spring cushion stop come in, and how do I order one?
Four finishes: 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 999033605 and Black is 999033693. Pick the code that matches the closer and balance of hardware on the opening.
7) Will a spring cushion stop hold up on an exterior door or a humid area?
The SCS-2 body is investment cast stainless steel, which PDQ specifies for corrosion resistance and durability, and the kit is a commercial grade item. Satin Stainless Steel (630) is the finish to specify where appearance matters outdoors; the PVD finishes, 605 Bright Brass and 613E Dark Oxidized Satin Bronze, are also plated for wear.
