Dormakaba 75233 LH 626 – Frequently Asked Questions

1) Is the Dormakaba 75233 pivot handed, and what does LH mean here?
Handing matters on this one. The 75233 LH is built specifically for left-hand door configurations, so it will not work on a right-hand opening. Determine the door's handing at the opening before ordering, and order the right-hand version if the door swings the other way.
2) Can I use the Dormakaba 75233 LH pivot on a fire-rated door?
Yes. The 75233 LH intermediate pivot is rated for use on fire doors with ratings up to three hours, which covers most stairwell, corridor, and fire barrier openings in commercial buildings.
3) What does an intermediate pivot actually do, and do I still need top and bottom pivots?
An intermediate pivot is a supplemental support point along the door height, not a replacement for the main pivots. The 75233 LH carries part of the load between the top and bottom pivots to steady a heavy door and reduce stress on them. You still need a top pivot and a bottom pivot or floor closer to hang the door.
4) What is the offset on the Dormakaba 75233 LH, and how does it mount?
It is a 3/4 inch offset pivot with a full mortise preparation, meaning both leaves mortise into the door edge and the frame for a flush, aligned mounting. Your frame and door prep has to match a 3/4 inch offset arrangement; a center-hung or butt-hung door is a different prep entirely.
5) Is the 75233 LH pivot heavy enough for a high-traffic commercial entrance?
It is heavy-duty steel and rated commercial, built for high-traffic commercial door assemblies rather than residential use. On tall or heavy doors the intermediate pivot is what keeps the load off the top pivot, so it is worth specifying on entries that see constant cycling.
6) What finish does the Dormakaba 75233 LH pivot come in?
One finish only: 626 satin chrome. That is the standard commercial finish code and it matches the satin chrome and satin nickel hardware on most office and institutional openings.
