Dormakaba 75323 LH 626 – Frequently Asked Questions

1) Is the Dormakaba 75323 bottom arm left-hand or right-hand, and can I flip it in the field?
The 75323-LH is a dedicated left-hand bottom arm. It is built for left-hand door handing and is not intended to be reworked in the field for a right-hand opening, so confirm the handing of the door before ordering. If the opening is right-hand, you need the right-hand version of the arm, not this one.
2) What does 3/4 inch offset hung mean on this Dorma bottom arm, and will it work on a center hung door?
Offset hung means the door pivots on an offset pivot set back from the face of the frame, with the 3/4 inch dimension defining the arm geometry that matches that pivot layout. The 75323-LH is made for a 3/4 inch offset hung installation only. On a center hung door the pivot sits on the door centerline and the arm geometry is different, so this bottom arm is the wrong part for that opening.
3) I am replacing a broken bottom arm on a pair of offset hung doors. Do I need one part number or two?
Two. Handing is per leaf, so a pair of offset hung doors takes one left-hand arm and one right-hand arm. The 75323-LH covers the left-hand leaf only; order the matching right-hand arm for the other leaf, and keep both on the same finish, 606 Satin Brass or 626 Satin Chrome, so the pair matches.
4) Can I use one bottom arm for both standard and heavy-duty Dorma closers?
Yes. The 75323-LH is rated for both standard and heavy-duty door closer applications, so it covers a range of commercial traffic levels rather than being limited to one duty class. That is useful for a property manager or MRO buyer standardizing spare parts across openings with mixed closer duty.
5) What finishes does the Dormakaba 75323-LH bottom arm come in?
Two finishes: 606 Satin Brass and 626 Satin Chrome. 626 Satin Chrome is the common commercial default and will match most existing closer and lock hardware; choose 606 Satin Brass where the opening is already on brass-toned trim.
6) Does the 75323-LH come with a cover cap or do I have to order it separately?
The cover cap is included with the arm. It conceals the mounting hardware and protects the internal components, so you do not need to source it as a separate line item to finish the install cleanly.
7) Is the Dorma 75323-LH a genuine replacement part or an aftermarket arm?
It is a genuine Dormakaba component from the Dorma Door Closer Parts and Accessories line, catalogued as a replacement part. For a locksmith or integrator servicing an existing Dorma closer, that means OEM fit and tolerances rather than an aftermarket approximation.
8) Is this arm rated for commercial traffic or is it a residential part?
Strictly commercial. The 75323-LH bottom arm is classified for commercial use and is aimed at office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential buildings and government properties, which is the traffic level a bottom arm on an offset hung door normally sees.
