Tim Weller of Allegion sent me today’s Fixed-it Friday photos of a fire door assembly. Most of you will remember that NFPA 80 allows the use of STEEL shims when shimming a door so the assembly complies with the clearance requirements of the standard. If you’re not familiar with shimming practices, there are complete instructions in this article from Laura Frye Weaver called ‘The Art of Shimming a Door.’
It looks like this installer wasn’t aware of the requirements of NFPA 80…

I see all kinds of issues with improper installation of rated doors. I find a lot of exit devices mounted to doors using TEK Self Drilling Lath screws. I fail every one of them for failing to use the manufacturer’s supplied hardware and for not following the manufacturer’s installation instructions.
As it should be!

So that’s what is required to make a McKinney hinge work? I guess they are also able to have a gap greater than 1/8″.
In a drywall frame no less! why not set the frame correctly. That is why the lowest bid(s)should be thrown out. Good labor isn’t cheap and cheap labor isn’t good.
Bryan, you reminded me of a jobsite I visited to see why the doors didn’t fit the frames.
The frames were set, THEN the floor was poured.
I have no idea what they did to fix it. I can only guess.
Fun times.
I wonder if LG has any memory of this.
I don’t remember that one, Lou!

At least the gap on the latch side looks compliant.
