1950s Era Commercial Door Lever


I'm replacing several door levers in a 1950's era office. Most have gone smoothly. One, not so much.

I've removed the interior handle and rose to reveal a heavy-duty, cast mounting plate. I removed the bolts securing the mounting plate, expecting to be able to unscrew the mounting plate from the threaded hub on the chassis assembly. However the mounting plate will not turn more than an eighth inch or so before come to a complete stop.

I've applied considerable force with a pipe wrench and am convinced that there's still some sort of locking mechanism in play that needs to be dealt with before the mounting plate can be removed.

Any insights?

Just a guess, but did you put a wrench on that threaded collar (or whatever it's called)? It looks like it's meant to be turned.

Re: 1950s Era Commercial Door Lever


Did you take both sides apart? I have seen some heavy duty handles that are screed together from both sides.

Thanks for feedback and suggestions. Some late night research led me to this page which both exactly describes my experience and the solution.

It appears a specialized wrench is required to remove a castle nut before the collar can be unscrewed.

I was eyeing that "castle nut", too. Thanks for posting it.

Re: 1950s Era Commercial Door Lever


you can use a modified piece of electrical conduit to get that off

That wrench posted brought back memories how we used to remove them when electric doorknobs started to come around in the early 80s.
Those are good knobs last a real long time

Usually somebody on site will have the spanner wrench for the locks. Facilities guy or janitor type. Root around in the basement or supply closet.

Re: 1950s Era Commercial Door Lever


Thanks for the follow up insights and suggestions. I was able to loosen and remove the castle nut with a couple of small screwdrivers. As usual, half the battle is just knowing what you're dealing with. This handle is definitely a nice piece of hardware. I'll be re-purposing it elsewhere in the building.

Glad you got it.
Here's a side by side pix of the wrench that went with 50s era knobs we removed, compared to the modern version for the new ones.
