Cal-Royal 945AR-ALU – Frequently Asked Questions

1) Is the Cal-Royal 945AR closer arm handed? Do I need a left hand and a right hand version?
Non-handed. One 945AR covers both left and right hand openings, so a maintenance shop can stock a single part number for every 900 Series closer in the building instead of splitting inventory by handing.
2) Is a regular arm the right choice, or do I need a hold open or cush arm?
The 945AR is a regular arm: it pushes the door closed and does nothing else, which is what most fire and smoke rated openings require since the door must be free to self close. If the opening needs the door to stand open, that is a different arm entirely, such as the Deltana DCHA1050 hold open arm for the DC10 closer. If you want the arm itself to stop the door instead of a floor or wall stop, that is a cushion arm, like the Deltana DCCA4041 for the DC40. Neither of those substitutes onto a Cal-Royal 900 Series closer; they mate with their own Deltana bodies.
3) My closer arm is broken but the closer body still works. Can I just replace the arm?
Yes, that is what the 945AR is for. On a surface mounted Cal-Royal 900 Series closer the arm is the sacrificial part, and swapping it restores closing action without pulling the body off the door or re-drilling the frame. If the body is leaking oil or won't hold a speed adjustment, the arm won't fix that.
4) The closer is in the floor, not on the door. Will a 945AR arm work?
No. The 945AR serves surface mounted closer systems mounted on the door or frame. A floor closer such as the Norton Rixson 28 Series, a center hung single acting heavy duty unit rated to 350 lbs door weight, or the 30 Series center hung double acting heavy duty closer rated to 200 lbs, drives the door from a spindle at the floor and uses its own top pivot and bottom arm hardware. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, which is the pivot-side hardware on that kind of installation rather than a surface closer arm.
5) Can a Deltana or LCN closer arm be used in place of a Cal-Royal 945AR?
No. The 945AR is built as a replacement main arm and regular forearm for Cal-Royal 900 Series surface mounted closers, and closer arms are matched to the pinion and body of their own series. The Deltana DCCA4041 cushion arm is built for the Deltana DC40 closer and the DCHA1050 hold open arm for the DC10 closer, so each stays with its own closer family. If the body on the door is a Cal-Royal 900 Series, the 945AR is the arm that fits it; if the body is a Deltana DC40 or DC10, the matching Deltana arm is the one to order.
6) There is no wall stop behind the door. Does a regular arm like the 945AR handle that, or is a cushion arm needed?
A regular arm such as the 945AR controls the door through its swing but does not itself stop the door at a set opening angle; that job belongs to a cushion or stop arm. The Deltana DCCA4041 is the cushion arm for the DC40 closer and is the arm type used where the swing has to be arrested by the closer arm instead of by a wall or floor stop. Where a stop is already in place and the arm only has to close the door, the 945AR regular forearm assembly is the straightforward choice on a Cal-Royal 900 Series body.
7) What does the Cal-Royal 945AR include, the whole arm or just one piece?
Both halves. The 945AR is a main arm plus regular forearm assembly, so a bent or sheared forearm and a stripped main arm are covered by the same order. You reuse the existing closer body, shoe screws and soffit plate on the frame.
8) Will a forged steel closer arm hold up on a high traffic entrance?
Main arm and forearm are both forged steel rather than cast, which is the construction Cal-Royal specifies for commercial door traffic. It is a commercial grade part, used on office buildings, schools, hospitals, retail and multi-tenant residential openings. The usual failure on a regular arm is abuse from someone forcing the door past its stop, so pair it with a working overhead or floor stop.
9) I have a floor closer, not a surface closer. Will this arm fit?
No. The 945AR is a surface mounted closer arm, and floor closers use a bottom arm or spindle arm instead. For center hung floor closer applications ZenSupply carries Norton Rixson units such as the 28 Series single acting and the 30 Series double acting, and Dormakaba offers a 1-1/2 inch offset bottom arm with cover for offset pivot floor closer openings.
10) My closer uses a track instead of a scissor arm. Is the 945AR a substitute?
No, and they are not convertible. The 945AR is a push or pull side arm and forearm that spans from the closer body to a soffit or frame bracket. A track closer carries a roller in a slide channel screwed to the frame face, so it needs a track, for example the LCN 4040SE-3038 standard track or the 4040SEH-3038 hold open track for 4000 Series bodies. Look at the existing hardware: two jointed steel links means arm, a single straight channel means track.
11) Do I need any brackets or a shoe support with the Cal-Royal 945AR arm?
On a standard replacement the 945AR reuses the mounting hardware already on the opening, so nothing extra is required. Reveal is the thing to check on a pull side install: if the frame face sits back far enough that the forearm can't reach the soffit plate at the right angle, you need a bracket, and that hardware is closer specific. LCN, for instance, sells the 1260-30 cush shoe support rated for a 3-1/16 inch reveal and the 1260-18QF quick fix bracket kit for its own 1000 Series closers. Measure the reveal before you order.
12) What is the difference between ordering a 945AR arm and ordering an LCN track?
They are two different ways of connecting the closer to the door. The 945AR is a two-piece arm, a forged steel main arm and regular forearm, that projects out from a surface mounted Cal-Royal 900 Series closer. The LCN 4040SE-3038 is a standard track for fire and life safety door closers in the 4040SE Series, where the arm roller runs inside a channel mounted along the frame or door. A closer designed for a swing arm takes the arm; a track closer takes the track. Confirm which the installed body is built for before ordering either.
13) Do I need one arm part number for left hand doors and another for right hand doors?
Not with the 945AR. It is non-handed, so the same part number serves either door handing and one line item covers both swings across a building. That matters for a maintenance stock: mounting accessories in this family are often reveal or opening specific instead, such as the LCN 1260-30 cush shoe support built for 3-1/16 inch reveal compatibility in the 1260 Series, or the LCN 1260-18QF quick fix bracket kit for 1000 Series closers. The 945AR is stocked by finish rather than by hand, in aluminum standard finish, black, duronodic, and gold.
14) What finishes does the Cal-Royal 945AR door closer arm come in?
Four finishes: aluminum (the standard), black, duronodic and gold. Match the arm to the closer body already on the door rather than to the door hardware, since a replacement arm in a different finish is the part everyone notices from the corridor.
