Cal-Royal 904 Parallel Arm Drop Bracket for 900 Series Door Closers

The Cal-Royal 904 Parallel Arm Drop Bracket is a non-handed accessory engineered for use with the 900 Series door closer line, designed specifically for non-hold open parallel arm applications. This drop bracket allows the closer arm to clear a surface-applied stop or holder, ensuring smooth, unobstructed door operation in commercial settings. Built for compatibility with the 900 Series, the 904 bracket is a required component whenever a surface-mounted stop or holder is present on the door or frame, making it an essential part for proper closer function and long-term reliability in high-traffic commercial doorways.

Key Features

  • Non-Handed Design: The 904 bracket installs on either left- or right-handed doors without modification, simplifying inventory and installation for contractors and facility managers.
  • Clears Surface-Applied Stops/Holders: Specifically engineered to allow the parallel arm closer mechanism to clear a surface-mounted stop or holder, preventing interference and ensuring proper door closing function.
  • Required for Non-Hold Open Applications: This drop bracket is a necessary accessory for parallel arm installations that do not utilize a hold-open feature, ensuring correct geometry and arm positioning.
  • 900 Series Compatibility: Purpose-built to integrate seamlessly with Cal-Royal 900 Series door closers, maintaining proper arm alignment and closer performance.
  • Commercial-Grade Application: Designed for use in commercial door control systems where surface-mounted stops or holders are part of the overall door hardware configuration.

Cal-Royal 904-ALUM – Frequently Asked Questions

1) When do I need a drop bracket on a parallel arm door closer?
You need one whenever a surface-applied stop or holder is mounted on the door or frame in the path of the closer arm. The Cal-Royal 904 drop bracket lowers the arm's mounting point so the parallel arm clears that stop or holder instead of binding against it. Without the bracket the arm geometry is wrong and the door won't close properly.
2) Will the Cal-Royal 904 bracket work on a hold-open parallel arm closer?
No. The 904 is specified for non-hold open parallel arm applications on the 900 Series. If you're running a hold-open arm, this isn't the right accessory for that geometry.
3) Does the 904 drop bracket have to be handed left or right?
It doesn't. The 904 is non-handed, so the same bracket installs on a left- or right-hand door with no modification. For a property manager stocking spares across a building, that means one part number covers every opening rather than two.
4) I have an LCN closer, not Cal-Royal. Is there an equivalent bracket?
The Cal-Royal 904 only suits Cal-Royal 900 Series closers. For LCN, the bracket accessories are series-specific too: the 1260-18QF Quick Fix Bracket Kit covers 1000 Series closers, and the 1260-30 Cush Shoe Support is the 1260 Series part sized for a 3-1/16 inch reveal. Match the accessory to your closer series, not just the function.
5) Is a drop bracket the same thing as a hold-open or cushion arm?
No, they solve different problems. A drop bracket like the Cal-Royal 904 only repositions the parallel arm lower so it clears a surface stop or holder. Arms such as the Deltana DCHA1050 hold open arm for the DC10 closer, or the DCCA4041 cushion arm for the DC40, change how the door behaves at the end of its swing. If you need stop-in-the-arm cushioning or a hold-open feature, the 904 won't give you either.
6) What is the difference between the Cal-Royal 904 drop bracket and a cush shoe support like the LCN 1260-30?
Both are parallel arm mounting accessories, but they solve different geometry problems. The Cal-Royal 904 is a drop bracket that lowers the parallel arm on a Cal-Royal 900 Series closer so the arm clears a surface-applied stop or holder mounted on the door or frame. The LCN 1260-30 is a cush shoe support for LCN closers rated for a 3-1/16 inch reveal, which addresses how far the frame face is set back from the door. If the obstruction is a surface stop or holder, the 904 is the part for a 900 Series closer; a deep reveal on an LCN 1260 Series installation is what the 1260-30 is for.
7) Can I use the Cal-Royal 904 bracket to stop the door instead of buying a separate overhead stop?
No - the 904 does not stop the door. It is a drop bracket that repositions the parallel arm on a Cal-Royal 900 Series closer so the arm clears a stop or holder that is already surface-applied to the opening; it assumes the stop exists rather than replacing it. Arm-based stopping on a surface closer comes from a cushion arm, such as the Deltana DCCA4041 cushion arm made for the Deltana DC40 closer. A cushion arm cushions the swing at the arm itself, while the 904 only changes mounting height so the arm has clearance.
8) We are specifying door control for a high-traffic entrance - should we add the 904 drop bracket or go with a floor closer?
The Cal-Royal 904 is an accessory for a surface-mounted commercial closer setup, used with 900 Series closers in parallel arm, non-hold open installations where a surface stop or holder is in the way. If the opening calls for a concealed floor closer instead of a surface closer, the drop bracket has no role and you would be selecting a floor closer outright - for example the Norton Rixson 28 Series center hung single acting heavy duty floor closer rated to 350 lbs door weight, the 328 Series at 325 lbs single acting, or the 30 Series double acting at 200 lbs, all Grade 1 heavy duty. Surface closer with a drop bracket and a center hung floor closer are two different door preps, so the decision is made before the bracket.
9) The closer on my door is a fire door closer - does the Cal-Royal 904 drop bracket apply?
The Cal-Royal 904 is a drop bracket for Cal-Royal 900 Series surface closers in parallel arm, non-hold open installations. For a fire and life safety track closer application, the accessory family is different: the LCN 4040SE-3038 is a standard track for fire/life safety door closers in the 4040SE Series, and it is a track rather than a parallel arm drop bracket. Confirm the closer body on the door first - the 904 fits 900 Series closer arms and does not adapt an LCN track closer.
10) What finishes does the Cal-Royal 904 parallel arm drop bracket come in?
Four: aluminum, black, duronodic, and gold. Pick the one that matches the closer body already on the opening, since the bracket sits right at the arm and is visible from the push side.
11) Is the Cal-Royal 904 bracket rated for commercial traffic?
It's a commercial door control accessory, intended for 900 Series closers in office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and government buildings. It is not a residential-grade part.
12) Is a Dorma offset bottom arm an alternative to the Cal-Royal 904 drop bracket?
They are not interchangeable. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty component that belongs to a pivot or floor closer bottom arm assembly and carries no fire rating. The Cal-Royal 904 is a non-handed drop bracket that mounts a Cal-Royal 900 Series surface closer's parallel arm lower so it clears a surface-applied stop or holder. One is part of the door's bottom hanging hardware; the other is overhead closer mounting hardware, so the choice follows the closer type on the opening.
13) I need the bracket to match my existing hardware finish - what finishes does the Cal-Royal 904 come in, and do the closer accessory alternatives offer the same?
The Cal-Royal 904 parallel arm drop bracket is offered in Aluminum, Black, Duronodic, and Gold, which covers the common commercial door hardware finishes on storefront and interior openings. Among the closer accessories from other makers, the comparable parts are defined by series fit rather than finish range - the Deltana DCCA4041 cushion arm is tied to the DC40 closer and the LCN 1260-18QF bracket kit to the 1000 Series - so finish matching across brands is secondary to confirming the accessory suits the closer body already installed.
