A place where I work has a set of swinging double action doors - Saloon doors or whatever you call them in your area of the world.
The assembly is on a metal frame which is almost dead plumb with some allowances for the 0 year old building settling,
The doors (a pair) are ~7' tall by 39" and 1 3/8" solid core veneered each, attached to the frame by 3 of 6" double action hinges. The left door, the one used most often, is sagging badly. The screws are tight.
Doing the "push against the edge and take the slack" method, there is considerable give at the top hinge.
I can't find anything on the internet about adjusting these so I'm assuming a complete replacement is necessary. Is that accurate?
My working career was in single and multi family unit repair and remodling, not commercial, so I've no expertise in these hinges.
Is my "guess" accurate?
