Cal-Royal 900HOSPRING-DURO – Frequently Asked Questions

1) What is the difference between the 900SPRING and 900HOSPRING arms for a Cal-Royal 900 closer?
The naming tells you the function. 900SPRING is the spring (parallel arm style) assembly; 900HOSPRING is the same spring arm with hold open, so the door parks at the open position instead of closing every time. Pick hold open for a receiving door, a break room, or anywhere staff want the door to stay put. Do not put hold open on a fire rated opening that has to self close. HOSRPS900 is the other hold open option in the 900 accessory range.
2) Can I replace just the arm on a Cal-Royal 900 closer, or do I have to replace the whole closer?
Just the arm. The 900 Series accessory range is sold as individual arm and part options, so a bent arm, a stripped shoe, or a failed hold open spring is a parts order rather than a closer replacement. Select the Arm Type that matches what is on the door now (900EXT, 900SPRING, 900HOSPRING, 901 / 902, 945AR, CR900HDAR, HOSRPS900, SPAS900 or TRACK / 900) and the finish to match the cover.
3) What do I have to specify when ordering a Cal-Royal 900 closer accessory?
Two things: Arm Type and Finish. Arm Type is the part itself, and there are nine choices in the 900 range, 900EXT, 900SPRING, 900HOSPRING, HOSRPS900, SPAS900, 901 / 902, 945AR, CR900HDAR and TRACK / 900. Finish is Aluminum, Black, Duronodic or Gold. Get the arm type off the closer already on the door, because that is the decision that determines whether the part bolts up.
4) Can a Cal-Royal 900 Series TRACK arm be used to replace a track on an LCN 4040SE closer?
No. The TRACK / 900 component is built for the Cal-Royal 900 Series closer platform. The track used on an LCN 4040SE closer is the LCN 4040SE-3038 standard track, which is a 4040SE Series part for fire and life safety door closers. Track geometry and closer arm attachment differ between platforms, so order the track that matches the closer brand and series on the opening.
5) I need a cushion or stop arm for a closer that is not Cal-Royal - what are my options?
The Cal-Royal 945AR and CR900HDAR arms cover heavy duty and stop arm needs on the Cal-Royal 900 Series. On a Deltana DC40 closer, the cushion arm is the Deltana DCCA4041. On an LCN 1260 closer, cush shoe support is handled by the LCN 1260-30, which suits a 3-1/16 inch reveal. Identify the closer series first, then pick the arm built for it.
6) I need a hold open arm for a Cal-Royal 900 door closer. Which option do I order?
Two hold open assemblies are offered in the 900 accessory range: 900HOSPRING and HOSRPS900. Both are ordered as an Arm Type selection, and each comes in Aluminum, Black, Duronodic and Gold. If the closer is mounted parallel arm with a shoe on the door, the spring style hold open is the one that matches that mounting. Hold open arms belong only on openings with no self closing requirement.
7) What finishes do Cal-Royal 900 Series closer arms come in?
Four: Aluminum, Black, Duronodic and Gold. Every arm type in the 900 accessory range is offered in all four, so a replacement arm can be matched to the closer cover already on the door rather than leaving one opening looking different from the rest of the floor. For a property manager standardizing a building, pick one finish and hold it across every 900 Series opening.
8) What is the CR900HDAR arm for on a Cal-Royal 900 closer?
CR900HDAR is the heavy duty arm option in the 900 accessory range, ordered the same way as the other arm types and available in Aluminum, Black, Duronodic and Gold. It is the choice for high traffic commercial openings, the kind of door in a school corridor or a hospital wing where a standard arm gets abused. 945AR is the other arm option alongside it.
9) Should I order a track arm or a regular swing arm for a Cal-Royal 900 closer?
That depends on projection. A track arm (TRACK / 900) runs the arm in a slide track along the door or frame, keeping the hardware tight to the opening, which is what you want on a corridor where a projecting arm gets caught or vandalized. A conventional arm like 900EXT or 900SPRING swings clear of the door and generally gives you more closing power on a heavier door. Whichever the closer was installed with is the safer replacement, because the mounting on the door already suits it.
10) Is a Deltana DCHA1050 hold open arm a substitute for a Cal-Royal 900 hold open arm?
No. The Deltana DCHA1050 is a hold open arm for the Deltana DC10 closer. The Cal-Royal 900HOSPRING and HOSRPS900 hold open components serve the Cal-Royal 900 Series. Both perform a hold open function, but they mount to different closer bodies, so one will not fit the other's shoe and pinion.
11) Would a Dorma 15323 offset bottom arm work in place of a Cal-Royal 900 Series arm?
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 belongs to a pivoted or bottom arm application rather than a surface closer arm. The Cal-Royal 900EXT, 945AR, and CR900HDAR arms attach to Cal-Royal 900 Series surface closers. The two solve different mounting arrangements on the opening.
12) Are Cal-Royal 900 Series closer accessories rated for commercial use or just residential doors?
Commercial. The 900 Series accessory range is a commercial door control part, used in office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and government buildings. That is the traffic level the arms are built around, and it is why the heavy duty CR900HDAR option exists alongside the standard arms.
