Dormakaba 75233 RH 626 – Frequently Asked Questions

1) Is the Dormakaba 75233 pivot handed, and what happens if I order the wrong hand?
Handing matters here. The 75233 RH is factory-configured for right-hand doors, so the offset geometry only lines up on an RH opening. Put it on a left-hand door and the pivot will not align with the existing mortise prep. Confirm the hand of the leaf at the door, standing outside the opening, before you order.
2) Can I use this intermediate pivot on a 3-hour fire rated door?
Yes. The 75233 RH is approved for use on fire doors rated up to three hours, which covers the rated corridor and stair openings in hospitals, schools, and government buildings. Doors rated below that (20 minute, 45 minute, 90 minute) are also covered by the same up-to-three-hour approval.
3) What does an intermediate pivot do, and do I still need a top and bottom pivot?
An intermediate pivot carries the door leaf between the top and bottom pivot points. It does not replace either one. On a center-hung or offset-pivoted heavy door you still need the top pivot and the bottom pivot or floor closer; the 75233 RH is the mid-height bearing point that takes weight off the other two and keeps a heavy fire door hanging true. It ships as a replacement part on its own, not as a complete pivot set.
4) Is the Dormakaba 75233 a 3/4 inch offset pivot?
It is a 3/4 inch full mortise offset pivot. That 3/4 inch offset is the hang dimension the door and frame must already be prepped for, so it swaps in where a 3/4 inch offset pivot set is installed. If your opening is center-hung or prepped to a different offset, this is the wrong pivot.
5) Will a genuine Dormakaba pivot work with my existing Dorma closer?
The 75233 RH is a genuine Dormakaba door closer part, made to fit within compatible Dormakaba closer and pivot systems. Match it to the pivot set already in the opening by hand and by the 3/4 inch offset dimension, since those two things decide whether it drops into the existing door and frame prep.
6) I manage a building with several rated corridor doors sagging at the hinge side. Is this the part I need?
If those doors hang on 3/4 inch offset pivots and the mid-height pivot is worn, the 75233 RH is the replacement for the right-hand leaves. It is a heavy-duty steel intermediate pivot for fire doors rated up to three hours. You will need the left-hand version for the LH leaves, and if the sag traces to the top or bottom pivot instead, replacing the intermediate pivot alone will not correct it.
7) What finish does the 75233 RH pivot come in?
One finish: 626 satin chrome. That is the standard commercial brushed-chrome tone, so it reads the same as 626 exit devices and closers on the rest of your openings. Since an intermediate pivot sits in the mortise between door and frame, very little of it shows once the door is hung anyway.
8) Is this pivot suitable for a residential door, or commercial only?
Commercial only. The 75233 RH is a heavy-duty steel pivot built for high-cycle rated openings, and it is specified as a commercial product. For a house door with a standard butt hinge prep, a pivot of this type is the wrong hardware entirely.
