Cal-Royal CR900HDAR-ALU – Frequently Asked Questions

1) Will the Cal-Royal CR900HDAR parallel arm fit any door closer, or only the CR900?
The CR900HDAR is built specifically for the Cal-Royal CR900 door closer. It is not a universal arm. If you are replacing an arm on an LCN, Norton, Dorma or Deltana closer, you need that manufacturer's own arm, since closer arms mount to a splined pinion shaft that is particular to the closer body.
2) Does the CR900HDAR parallel arm have to be ordered left hand or right hand?
No handing to specify. The CR900HDAR is non-handed, so one part covers both left and right hand openings. That is useful if you are stocking spares for a building with doors swinging both ways.
3) Is a heavy-duty parallel arm worth it, or will a standard arm do?
It depends on how the door gets treated. The CR900HDAR uses a forged steel main arm and forearm and is meant for potentially abusive installations, the kind where a standard arm bends or breaks early. On a low-traffic interior office door a standard arm is fine. On school corridors, warehouse doors, dorms, or any opening where people push through hard or the door gets slammed into a wall, the forged arm is the one that survives.
4) Can I order just the arm to repair a broken CR900 closer, or do I need the whole closer?
Just the arm. The CR900HDAR is sold as a replacement part for the CR900 closer, so if the arm is bent or sheared but the closer body still controls and does not leak oil, you replace the arm and keep the body. If the body is weeping fluid or has lost its hydraulic control, the arm will not fix it.
5) We need the door to stay open. Is there a hold-open arm comparable to the CR900HDAR?
The CR900HDAR is a heavy-duty parallel arm for the Cal-Royal CR900 and is not described as a hold-open arm. If hold-open function is the requirement, hold-open arm hardware exists in other closer lines - the Deltana DCHA1050 is a hold-open arm for the DC10 door closer, and the LCN 4040SEH-3038 is a hold-open track in the 4000 Series. Each of those is tied to its own closer series, so the choice follows whichever closer body is mounted on the opening.
6) Can an LCN 4040SE-3038 track be used instead of the Cal-Royal CR900HDAR parallel arm?
No. The CR900HDAR is a non-handed parallel arm built specifically for the Cal-Royal CR900 door closer, with a forged steel main arm and forearm. The LCN 4040SE-3038 is a standard track for fire/life safety door closers in the 4040SE Series, so it is a track-arm component matched to LCN closer bodies, not a swing-arm replacement for a CR900. Arm and track hardware is closer-specific, so order the arm that matches the closer body already on the door.
7) What finishes does the Cal-Royal CR900HDAR heavy-duty arm come in?
Four: aluminum (the standard finish), black, duronodic, and gold. Pick the one that matches the CR900 closer body already on the door so the arm does not read as a mismatched repair.
8) What is the difference between a parallel arm and a regular arm mount on a door closer?
A parallel arm mounts the closer on the pull side of the door with the arm running parallel to the face of the door when closed, so the whole assembly tucks in tight and gives vandals less to grab. A regular arm projects out perpendicular from the door and is more exposed. The CR900HDAR is the parallel arm version for the CR900 closer, which is why it pairs naturally with abuse-prone commercial openings.
9) Is the CR900HDAR arm a surface mounted part or does it need door prep?
Surface mounted. The arm bolts to the closer pinion and to a soffit or bracket on the frame, so it swaps onto an existing CR900 installation without cutting or morticing the door. It is a commercial-duty component, not a residential one.
10) Will a heavy-duty parallel arm stop the door from slamming into the wall behind it?
Not by itself. The CR900HDAR is a standard heavy-duty parallel arm, not a cush or stop arm, so it does not build in a backcheck stop at the arm. For a built-in stop you want a cushion or dead-stop style arm, for example the Deltana DCCA4041 cushion arm on a DC40 closer, or add a separate overhead or floor stop to the opening.
11) Does the CR900HDAR arm mount to the frame soffit or to the door face?
Parallel arm mounting puts the closer body on the door, pull side, and the forearm shoe on the frame soffit above the door. You need enough flat soffit on the frame to land the shoe; on frames with a deep reveal or no usable soffit, a parallel arm installation will not work and you should mount regular arm on the push side instead.
12) Is this the right part for a floor closer?
No. The CR900HDAR is an arm for a surface mounted overhead closer. Floor closers such as the Norton Rixson 28 Series single acting or the 30 Series double acting use bottom arms and spindles, not a surface parallel arm, and nothing from the CR900 family crosses over to them.
13) What is the difference between the CR900HDAR and a cushion or cush-shoe arm?
The CR900HDAR is a non-handed parallel arm for the Cal-Royal CR900, built from forged steel for potentially abusive installations. A cushion-style arm adds a built-in backcheck stop at the forearm to catch the door before it hits a wall - the Deltana DCCA4041 is a cushion arm for the DC40 closer, and the LCN 1260-30 is a cush shoe support sized for a 3-1/16 inch reveal in the 1260 Series. If the opening needs an integral stop rather than reinforced strength alone, that is a different arm style, and each of those parts is matched to its own closer.
14) Our doors keep getting the closer arms torn off. Is a heavier closer a better answer than the CR900HDAR arm?
The CR900HDAR is the heavy-duty route within a surface-mounted Cal-Royal CR900 installation - forged steel main arm and forearm, made for potentially abusive openings, and non-handed so one part covers either hand. Where the abuse is severe enough that a surface closer and its arm are the wrong approach entirely, floor closers move the mechanism into the floor: the Norton Rixson 28 Series is a center hung single acting heavy duty floor closer rated to 350 lbs door weight, and the 30 Series is center hung double acting rated to 200 lbs, both Grade 1. That change requires floor prep and a center hung door, so it is a different scope of work than swapping an arm.
15) Is the CR900HDAR a mounting bracket, or does it include one?
The CR900HDAR is the arm assembly itself - a non-handed parallel arm with forged steel main arm and forearm for the CR900 closer. It is not a bracket kit. Bracket and shoe accessories are separate items in closer lines; the LCN 1260-18QF, for example, is a quick fix bracket kit for 1000 Series door closers. If the frame condition calls for a bracket or drop plate in addition to the arm, that is ordered as its own part.
