Dormakaba 75323 3/4" Offset Hung Bottom Arm with Cover Cap

The 75323 bottom arm pack is built for Dormakaba LM Series 3/4 inch offset hung pivot sets and BTS Series 3/4 inch offset hung concealed floor closers. The match that matters is the offset: it is a 3/4 inch offset arm, so it belongs on 3/4 inch offset hung openings only. If your pivot set or floor closer is center hung or a different offset, this arm is the wrong part.

Handing is required. The 75323 is offered LH and RH, and each finish is available both ways, so you pick the hand at the order form. Stand outside the door (the side you push from is not the reference, the hinge side is): a bottom arm is machined for one hand and will not mount on the opposite swing. Get the hand off the existing door before ordering a replacement.

No. The Deltana DCCA4041 is a cushion arm for the DC40 door closer and the DCHA1050 is a hold open arm for the DC10 door closer -- both are arms for surface mounted closers that connect the closer body to the door or frame face. The Dormakaba 75323 is a bottom arm for 3/4 inch offset hung applications, sized 6-3/8 inches long by 13/16 inches wide, and it carries the door at the bottom rail in conjunction with LM Series 3/4 inch offset hung pivot sets and BTS Series 3/4 inch offset hung concealed floor closers. The two arm types mount in different places on the opening and are not interchangeable.

Aluminum, wood, or steel doors, as long as the opening is hung on a 3/4 inch offset. That covers the usual mix on a commercial entrance: an aluminum storefront leaf, a hollow metal door on a floor closer, or a solid wood door in a lobby. It is a commercial part, not a residential closer accessory.

The cover cap comes with it. The 75323 is sold as a bottom arm pack with the cover cap included, so the exposed arm at the bottom of the door is finished without a second line item. The cap is supplied in the finish you select.

They belong to different closer architectures. The LCN 4040SE-3038 is a standard track for 4040SE Series fire/life safety door closers and the 4040SEH-3038 is a hold open track in the 4000 Series; the LCN 1260-30 is a cush shoe support for 1260 Series closers with 3-1/16 inch reveal compatibility, and the LCN 1260-18QF is a quick fix bracket kit for 1000 Series closers. All of those mount on the face of the door or frame with a surface applied closer. The Dormakaba 75323 is a 3/4 inch offset hung bottom arm, 6-3/8 inches long, that pairs with LM Series offset hung pivot sets and BTS Series concealed floor closers, so the closer itself sits in the floor rather than on the head.

No. The Cal-Royal 900 Series accessories kit is a commercial door control accessory package tied to Cal-Royal 900 Series closers. The Dormakaba 75323 is a handed part -- it is ordered left hand or right hand -- with a 3/4 inch offset, 6-3/8 inch length and 13/16 inch width, and it is matched to LM Series 3/4 inch offset hung pivot sets and BTS Series 3/4 inch offset hung concealed floor closers on aluminum, wood or steel doors. Because the arm has to match both the pivot geometry and the handing of the opening, a general accessories kit for another manufacturer's closer series will not fit.

Four: 606 satin brass, 613 oil rubbed bronze, 625 bright chrome, and 626 satin chrome. All four are offered in both left hand and right hand. On a building where the bottom arms are visible at every entrance, 626 satin chrome is the usual match to satin aluminum and brushed stainless trim, and 613 to dark bronze storefront.
