Cal-Royal 704-DURO – Frequently Asked Questions

1) What is the Cal-Royal 704 flat drop bracket used for on a door closer?
The 704 is a flat drop bracket for Cal-Royal 300 Series surface door closers. A drop bracket lowers the closer body below the frame face so the closer can still be mounted where the header, stop, or frame face does not give you the flat mounting surface the closer needs. It is a mounting accessory only, so you order it alongside a 300 Series closer, not instead of one.
2) Do I need to order a left hand or right hand version of the Cal-Royal 704 bracket?
Neither. The 704 is non-handed, so the same bracket goes on a left hand or right hand opening. For a property manager or a shop stocking spares, that means one part number covers every door in the building instead of two.
3) Will the Cal-Royal 704 bracket fit a closer other than the 300 Series?
It is built specifically for the Cal-Royal 300 Series closer, and that is the only closer line it is stated to fit. If you are working on another manufacturer's closer, match the bracket to that brand's own accessory line instead. For LCN closers, for example, the 1260-18QF Quick Fix bracket kit serves the 1000 Series, and the 1260-30 Cush Shoe Support handles a 3-1/16 inch reveal.
4) My reveal is deep and the closer shoe will not land on the frame face - what do I use instead of a flat drop bracket?
A flat drop bracket like the Cal-Royal 704 lowers the mounting point on the frame or door face; it does not solve a deep reveal on a cush-arm installation. For that condition on an LCN closer, the 1260-30 cush shoe support is built for 3-1/16 inch reveal compatibility. Confirm the actual reveal at the opening before picking either part.
5) What finishes does the Cal-Royal 704 drop bracket come in?
Three: aluminum, duronodic, and gold. Pick the one that matches the closer body already on the opening so the bracket does not read as a repair. Duronodic is the dark bronze tone commonly paired with bronze aluminum storefront; aluminum suits clear anodized frames.
6) Is a flat drop bracket what I need, or do I need a different closer arm or track?
A drop bracket is for a mounting-surface problem: the closer shoe or body has nowhere flat to land on the frame. If your issue is instead how the door behaves, you want an arm or a track. A cushion or hold open arm, like the Deltana DCCA4041 cushion arm for the DC40 or the DCHA1050 hold open arm for the DC10, controls stop and hold open. A track, like the LCN 4040SE-3038 standard track or the 4040SEH-3038 hold open track, changes the mounting geometry of the closer itself. The 704 does none of that; it only gets a 300 Series closer onto the frame.
7) My door closer needs to go on a frame with no flat header surface. Will this bracket solve that?
That is exactly the case a drop bracket is made for. The 704 gives a 300 Series closer a flat, lowered mounting surface so you can mount on openings where the frame face or stop does not present one. It mounts on the surface, so nothing in the door or frame has to be cut or prepped beyond fastener holes.
8) Can I use the Cal-Royal 704 as a replacement bracket on an existing 300 Series closer install?
Yes. It is sold as a proper-fit replacement or upgrade component for 300 Series closer installations, so a maintenance team can swap a damaged or wrong-finish bracket without touching the closer body. Match the finish to the existing hardware when you order.
9) Do I need a handed version of the Cal-Royal 704, the way some closer arms are handed?
No. The Cal-Royal 704 flat drop bracket is non-handed, so the same part serves left- and right-hand openings and a property manager can stock one line item across a building. Some closer accessories are series-and-function specific instead, such as the Deltana DCHA1050 hold open arm for the DC10 closer or the Deltana DCCA4041 cushion arm for the DC40 - those are chosen by closer series and arm function, not by a single universal part.
10) The Dorma 15323 offset bottom arm came up in my search for drop brackets - is it the same kind of part?
They serve different jobs. The Cal-Royal 704 is a surface mounted flat drop bracket for 300 Series closers on a conventional overhead installation. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part that is not fire rated. If your search is driven by an offset condition at the bottom of the door, the 704 will not address it.
11) Can I use a Cal-Royal 704 bracket to mount a floor closer?
No. The 704 is a surface mounted flat drop bracket for 300 Series overhead door closers. Floor closers mount in the floor with their own case - the Norton Rixson 403000 heavy duty center hung floor closer, for example, is supplied with a cement case and carries a 300 lb door capacity. That is a different installation entirely and takes no drop bracket.
12) Is the Cal-Royal 704 bracket rated for commercial traffic, or is it a residential part?
Commercial. It is catalogued as a commercial door control component and is used in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings. That is the same duty environment the 300 Series closer itself is installed in.
