Cal-Royal RHDSTP Cushion Heavy Duty Stop Arm for N900PBF Door Closer

The Cal-Royal RHDSTP is a Cushion Heavy Duty Stop Arm engineered for use with the N900PBF door closer, delivering a cushioned opening function for both regular and top jamb applications. This non-handed arm supports stop angles of 85°, 90°, 95°, 100°, 105°, and 110°, and accommodates a 0"-3 ½" (0-89mm) reveal range, making it a versatile replacement or upgrade component for commercial door closer installations. As a functional equivalent to the Dorma 8600 Series Cushion IS Arm and the Norton 1600 Series 7701-CA Arm, it offers a reliable cross-compatible option for facilities standardizing on cushioned-arm door closer hardware.

  • Non-Handed Design: Simplifies ordering and installation since the arm works regardless of door handing.
  • Cushioned Opening Function: Designed to absorb shock at the end of the door swing, reducing wear on the door, frame, and closer.

Cal-Royal RHDSTP-ALUM – Frequently Asked Questions

1) Can I set the door to stop at 90 degrees with this arm?
Yes, and at five other positions. The cushion arm gives stop points at 85, 90, 95, 100, 105 and 110 degrees, so you can hold the door off a wall, a radiator, or an adjacent leaf without adding a separate floor or wall stop.
2) My closer is an LCN, not a Cal-Royal. Is there a cushion accessory for that instead?
The RHDSTP will not fit an LCN closer; it is made for the Cal-Royal N900PBF. For LCN cush applications, the LCN 1260-30 cush shoe support is the equivalent accessory and is rated for a 3-1/16 inch reveal. On a Deltana DC40 closer, the cushion arm is the DCCA4041.
3) If I need a cushion arm for a Deltana DC40 closer, will the Cal-Royal RHDSTP work?
No. The RHDSTP cushion heavy duty stop arm is purpose-built for the Cal-Royal N900PBF closer. For a Deltana DC40 body, the matching part is the Deltana DCCA4041 cushion arm, which is built for the DC40 series. Cushion arms are not interchangeable across closer bodies, so match the arm to the closer casting you already have on the door.
4) Do I need to specify left hand or right hand for this Cal-Royal stop arm?
No handing to specify. The RHDSTP is non-handed, so one part number covers both left and right hand openings. That is useful if you are stocking spares for a building with doors swinging both ways.
5) Will this arm work in a top jamb mount, or only regular arm mount?
Both. The RHDSTP is set up for regular arm and top jamb applications, which covers the usual pull-side and push-side-of-frame installs on a commercial opening.
6) What is a cushion stop arm actually doing, and do I still need a wall stop?
A cushion arm absorbs the shock at the end of the opening swing and stops the door at the set angle, which takes the abuse off the door, frame and closer instead of letting it land on a separate stop. On a high traffic commercial opening that is often used in place of a wall or floor stop, though many specs still call for a secondary stop as backup.
7) Is an LCN 4040SE-3038 track a substitute for the Cal-Royal RHDSTP?
No - they are different mechanisms. The RHDSTP is a swing-arm cushion stop for the Cal-Royal N900PBF, mounted regular arm or top jamb. The LCN 4040SE-3038 is a standard track for the 4040SE Series fire and life safety closers, meaning the closer arm rides in a slide track rather than projecting as a scissor-style arm. A closer designed for track operation cannot take a cushion stop arm, and vice versa.
8) What finishes does the Cal-Royal RHDSTP stop arm come in?
Four: aluminum, black, duronodic and gold. Duronodic is the dark bronze tone that matches most bronze anodized aluminum storefront, and aluminum matches clear anodized frames.
9) Is this stop arm rated for commercial traffic or is it a residential part?
Commercial. It is classified as a commercial, surface mounted door control part and built as a heavy duty stop arm for high traffic openings such as schools, hospitals, retail and government buildings.
10) The frame face where the closer shoe lands is damaged - do I need a new cushion arm or a bracket?
Those are two different fixes. The RHDSTP cushion heavy duty stop arm replaces the arm assembly itself on an N900PBF closer and sets the stop angle between 85 and 110 degrees. If the mounting surface rather than the arm is the problem, a bracket kit is the part - the LCN 1260-18QF quick fix bracket kit serves that role on 1000 Series closers. Confirm whether the wear is in the arm linkage or the mounting point before ordering.
11) For a high traffic entry, is a cushion stop arm enough or should I look at a floor closer?
The RHDSTP is a heavy duty cushion stop arm for commercial surface mounted closer applications, absorbing shock at the end of the swing to reduce wear on the door, frame and closer. Where the door itself is very heavy, a floor closer is the different approach - the Norton Rixson 40 Series is a Grade 1 heavy duty center hung floor closer with cement case rated to 300 lb door capacity. The RHDSTP upgrades the stop behavior of an existing overhead closer; the floor closer changes the whole control method and requires floor preparation.
