Cal-Royal HOSRPS/900 Super Rigid Parallel Arm Stopper Hold Open Door Closer Arm

The Cal-Royal HOSRPS/900 is a super rigid parallel arm stopper hold-open designed to deliver dependable door control for commercial door closer installations. This non-handed unit features a stop built directly into the soffit shoe, with a convenient handle that controls the hold-open function for flexible, on-demand operation. Equivalent to the LCN H-CUSH ARM, it is engineered as a direct-fit replacement or upgrade component for facilities standardizing on proven parallel arm hardware, and it is available in US3 and US26 finishes to complement existing door hardware finishes.

Key Features

  • Non-Handed Design: Works on either handing without the need for handing-specific ordering, simplifying stock and installation.
  • Integrated Soffit Shoe Stop: The stop is built into the soffit shoe for a clean, low-profile installation without additional hardware.
  • Handle-Controlled Hold-Open: A dedicated handle allows facility staff to engage or release the hold-open function as needed for traffic flow or ventilation.
  • LCN H-CUSH ARM Equivalent: Cross-compatible with LCN H-CUSH ARM specifications, making it a suitable replacement part for existing installations using that reference component.
  • Super Rigid Construction: Built as a heavy-duty parallel arm assembly for reliable, long-term performance in commercial door control applications.
  • Finish Options: Offered in US3 and US26 to match surrounding door hardware and overall door control system aesthetics.

Cal-Royal HOSRPS / 900-ALU – Frequently Asked Questions

1) Will the Cal-Royal HOSRPS/900 parallel arm work as a replacement for an LCN H-CUSH ARM?
Yes. The HOSRPS/900 is built as an equivalent to the LCN H-CUSH ARM, so it drops in as a replacement or upgrade where that arm is already specified. That is the main reason facilities standardizing on parallel arm hardware buy it: the closer body stays, the arm swaps.
2) Is the Cal-Royal HOSRPS/900 hold open arm handed, or do I need to order left and right?
Non-handed. One part covers both left and right hand doors, so stocking it for a building with mixed swings only takes one line on the order. Nothing needs to be specified for handing.
3) Do I need a separate overhead stop if I use the Cal-Royal HOSRPS/900 arm?
No separate stop is needed. The stop is built into the soffit shoe on the HOSRPS/900, so the arm itself limits the door swing without a second piece of hardware on the frame or the door face. That is the whole point of a cush arm: stop and closer arm in one assembly.
4) I need a hold open arm but my closer is a Deltana DC10 or DC40. Will the Cal-Royal HOSRPS/900 fit?
Closer arms are matched to the closer body, and the HOSRPS/900 is the Cal-Royal super rigid arm built to LCN H-CUSH ARM specifications. For Deltana bodies, go to the arm made for that closer: the DCHA1050 hold open arm for the DC10, or the DCCA4041 cushion arm for the DC40.
5) Can I use the Cal-Royal HOSRPS/900 hold open arm on a fire rated door?
A mechanical hold open arm keeps a door propped until someone releases the handle, which is the opposite of what a fire door needs. Fire rated openings require self-closing and latching, with any hold open tied to the alarm through an electromagnetic or fusible link device. For a fire and life safety opening, use a track built for it, such as LCN's 4040SE-3038 standard track for fire/life safety door closers.
6) What is the equivalent Cal-Royal arm for an LCN H-CUSH ARM parallel arm closer?
The Cal-Royal HOSRPS/900 is a super rigid parallel arm stopper hold-open built as an equivalent to the LCN H-CUSH ARM, with the stop integrated into the soffit shoe and a handle that controls the hold-open function. It is non-handed, so one part covers both hands of door, and it comes in US3 polished brass and US26 polished chrome as well as aluminum, black, duronodic and gold.
7) If the closer needs a hold-open track instead of a parallel arm, what part covers that?
A track closer takes a track, not an arm. The LCN 4040SEH-3038 hold open track is a 4000 Series door closer accessory, and the LCN 4040SE-3038 standard track serves 4040SE Series fire and life safety door closers where the door must be free to close. The Cal-Royal HOSRPS/900 is a parallel arm assembly with the stop built into the soffit shoe, so it mounts to an arm-type closer rather than a track.
8) What is the difference between a cushion arm and a hold open arm on a door closer?
A cushion arm absorbs the door at the end of its swing and stops it; a hold open arm keeps the door standing open until it is released. The Deltana DCCA4041 is a cushion arm for the DC40 closer and the Deltana DCHA1050 is a hold open arm for the DC10 closer, so the two are not interchangeable even within one brand. The Cal-Royal HOSRPS/900 does both jobs in one assembly: the stop is integrated into the soffit shoe and a handle engages or releases the hold-open.
9) How does the hold open work on the Cal-Royal HOSRPS/900 arm, and can staff turn it off?
A handle on the arm controls the hold open, so staff engage or release it by hand at the door. Prop the door for deliveries or ventilation, then release it when you want the door closing normally again. There is no template change or tool needed to switch between the two.
10) Should I use a cush arm like the Cal-Royal HOSRPS/900 or a hold open track closer?
A cush arm mounts parallel on the push side and puts the stop in the soffit shoe, so the door is stopped and held by the arm itself. A track closer instead runs a slide arm in a track along the door: LCN's 4040SEH-3038 hold open track and the plain 4040SE-3038 track are that style. Cush arms take abuse better on exterior and high traffic doors where the door gets thrown open; tracks sit lower profile and are the choice when the parallel arm projection is not wanted.
11) My parallel arm mount has a deep reveal and the cush shoe will not reach. What do I need?
The HOSRPS/900 arm itself does not solve reveal depth; that is a bracket problem. For deep reveals on cush shoe installations, LCN's 1260-30 cush shoe support covers reveals to 3-1/16 inches. Where the frame face will not take a standard mount, the LCN 1260-18QF quick fix bracket kit is the other route.
12) Does the Cal-Royal HOSRPS/900 include the door closer, or is it just the arm?
Just the arm. The HOSRPS/900 is a parallel arm assembly sold as a replacement or upgrade component for an existing surface mounted closer. The closer body, and the mounting screws for it, are not part of it.
13) Can a cush shoe support be used in place of a parallel arm hold open arm?
No. The LCN 1260-30 cush shoe support is a mounting support for door closers with 3-1/16 inch reveal compatibility, so it addresses the reveal at the soffit rather than providing the stop and hold-open action. The Cal-Royal HOSRPS/900 is the arm assembly itself, carrying the stop in the soffit shoe with a handle for the hold-open function. A deep reveal condition can call for both the arm and a support, not one substituting for the other.
14) Is a Dorma offset bottom arm a substitute for a parallel arm hold open?
No. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part that is not fire rated, and it connects a floor or pivot closer at the bottom of the door. The Cal-Royal HOSRPS/900 is a super rigid parallel arm assembly mounted overhead with the stop in the soffit shoe and a handle-controlled hold-open, so the two serve different closer types and different positions on the door.
15) What finishes does the Cal-Royal HOSRPS/900 parallel arm come in?
Six: US3 polished brass, US26 polished chrome, aluminum, black, duronodic, and gold. Duronodic and aluminum are the usual matches for storefront and commercial aluminum entrances, while US3 and US26 line up with brass or chrome lever and closer finishes already on the opening.
16) Is the Cal-Royal HOSRPS/900 arm suitable for a school or hospital entrance, or is it light duty residential hardware?
It is commercial hardware, a super rigid surface mounted parallel arm assembly meant for door closer installations in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings. It is not a residential grade part.
17) Does replacing a closer arm also require a new mounting bracket?
Sometimes the frame condition is the issue rather than the arm. The LCN 1260-18QF quick fix bracket kit is a 1000 Series bracket kit for door closers and addresses the mounting surface. The Cal-Royal HOSRPS/900 replaces the parallel arm itself and is non-handed, so the same part serves either hand of door without ordering a specific handing.
