Cal-Royal 900EXT-GOL – Frequently Asked Questions

1) Will the Cal-Royal 900EXT long arm work on a door with a deep top jamb reveal?
That is exactly what the 900EXT is built for. It's an extended arm with a 3 inch extension, so it reaches across a top jamb reveal that a standard 900 Series arm can't span. If your closer body mounts on the door and the frame face sits back too far for the stock arm to make the shoe connection, this is the arm that closes that gap.
2) If a door needs hold-open rather than extra reveal reach, what closer arm should be used instead of the Cal-Royal 900EXT?
The 900EXT is a reach part, not a function part. It is an extended long arm with a 3 inch extension for deep top jamb reveals on 900 Series closers, and it does not add hold-open. For hold-open, the arm has to be built for it: the Deltana DCHA1050 is a hold open arm for the DC10 door closer, and the LCN 4040SEH-3038 is a hold open track for 4000 Series closers. Each is tied to its own closer line, so the hold-open decision usually follows whichever closer body is on the opening.
3) What is the difference between the Cal-Royal 900EXT arm and the LCN 1260-30 cush shoe support?
Both address reveal depth, but they do it at different ends of the installation. The Cal-Royal 900EXT is an extended long arm with a 3 inch extension for 900 Series door closers, reaching across deep top jamb reveals from the closer body. The LCN 1260-30 is a cush shoe support, a 1260 Series part rated for 3-1/16 inch reveal compatibility, that mounts at the shoe end. Match the part to the closer you already have on the door: the 900EXT is built for the Cal-Royal 900 Series, the 1260-30 for LCN 1260 Series closers.
4) Does the Cal-Royal 900EXT arm stop a door from slamming into an adjacent wall?
No. The 900EXT is an extended long arm with a 3 inch extension that lets a 900 Series closer work on doors with deep top jamb reveals; its job is mounting geometry. Backcheck-style wall protection at the arm comes from a cushion arm such as the Deltana DCCA4041, which is built for the DC40 door closer. If the opening needs both a deep reveal solution and a cushion stop, those are two different arms on two different closer platforms, so confirm which closer body is installed before ordering.
5) What finishes does the Cal-Royal 900EXT extended arm come in?
Four: standard aluminum, black, duronodic, and gold. Duronodic is the dark bronze tone that matches most bronze-anodized storefront and commercial frames, and aluminum is the default if you're matching a mill-finish closer already on the door. Pick the one that matches the closer body, not the door.
6) Should I use an extended arm or a different closer mounting when the reveal is too deep?
Two ways to solve a deep reveal. An extended arm like the Cal-Royal 900EXT adds 3 inches of reach and keeps your existing closer body and mounting, so it's the lower-disruption fix. The alternative is a bracket or shoe support that repositions the connection instead, the way the LCN 1260-30 handles a 3-1/16 inch reveal on 1260 Series closers. Either approach is closer-brand-specific, so match the accessory to the closer you already have on the door.
7) Do I need to order a left hand and right hand version of an extended closer arm like the Cal-Royal 900EXT?
The Cal-Royal 900EXT is a non-handed extended long arm, so one part covers both swings and stocking it for a mixed building does not mean carrying pairs. It comes in aluminum standard finish, black, duronodic, and gold, so the choice on a repeat order is finish rather than hand. Compare that to hold-open and cushion arms such as the Deltana DCHA1050 for the DC10 closer and the Deltana DCCA4041 for the DC40 closer, which are each tied to a specific closer series and must be matched to the closer body on the door.
8) Can a fire door use the Cal-Royal 900EXT arm, or is a different door control accessory required?
Fire and life safety openings are usually specified as a closer-and-track package rather than an arm swap. The LCN 4040SE-3038 is a standard track for fire/life safety door closers in the 4040SE Series, which is the part written into that kind of spec. The Cal-Royal 900EXT is an extended long arm with a 3 inch extension for 900 Series closers, intended for deep top jamb reveals in commercial applications including healthcare institutions and government and municipal buildings. On a labeled opening, follow the closer manufacturer's listed assembly for the closer already on the door.
9) What is a simpler alternative to the Cal-Royal 900EXT arm when a surface closer will not land on the frame?
When the obstacle is a mounting surface rather than reveal depth, a bracket kit is the lighter fix. The LCN 1260-18QF quick fix bracket kit is a 1000 Series accessory that gives a surface closer something to mount to. The Cal-Royal 900EXT solves a different problem: it is an extended long arm with a 3 inch extension that carries a 900 Series closer across a deep top jamb reveal. Decide by what is short at the opening, the mounting surface or the reach, and by which closer line is installed.
10) Is the Dorma 15323 offset bottom arm a substitute for the Cal-Royal 900EXT?
No, they serve opposite ends of the door. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part carrying a fire rating of No, and it works at the bottom pivot of an offset hung door. The Cal-Royal 900EXT is an extended long arm with a 3 inch extension that mounts at the top with a 900 Series surface closer to clear a deep top jamb reveal. A bottom arm cannot take the place of a top-mounted closer arm.
11) Is the Cal-Royal 900EXT arm rated for commercial traffic or is it a residential part?
Commercial. The 900EXT is a commercial-grade surface mounted closer accessory, and it goes into office buildings, schools, healthcare facilities, retail, warehouses, and government buildings. It is not a light residential arm.
