attachments to fire rated doors

[Paul Linder]

Where would we find reference to what can be attached to a fire rated door? Specifically, can a door bumper such as the Keedex Protect-A-Lok part number K-12 made of lexan polycarbonate be attached to a hospital fire rated door, or does it need to be the stainless steel K-12S?

Field modifications are limited by NFPA 80 to jobsite preparation for:

● surface-applied hardware;

● function holes for mortise locks;

● holes for labeled viewers;

● protection plates; and
● a maximum 3/4-inch (19-mm) wood and composite door undercutting.

I see them (K-12) in every hospital I work in as well as other facilities. I use them often as well. I have not heard of any of these installs being flagged by AHJ. From my understanding, as long as the penetration's are covered and do not exceed 1" in diameter you're good.

Check with CAL-OSHA in California, doesn't sound as if they would approve it. What does NFPA say about altering rated doors?

I've been fitting some fire doors and linings supplied by howdens. Size are 1981x762 doors Frames supplied to suit doors. However the linings are only 765 wide. I've hinged with a 2mm gap hinge side and that's the minimum I can go max 4mm This means the door doesn't sit into the frame. I've measure some others from different suppliers with an internal width of 769. The doors are pre finished so although I could plane to suit I don't see as this is right and not something I've come across before I've spoken with howdens and they are speaking with the manufacturer on the issue but I just want some advice from carpenters on whats the norm. Should the door swing into the lining without being trimmed. Or is it sometimes acceptable for a door to be trimmed to suit. BTW this 765 measurement is at the head. I could alter the linings at the head but I don't see this as something I should have to do.

where is the best place to buy 20 min fire rated doors I went to home depot , the average cost for customized door may reach over 500$ with painting and tax So any store or types recommendations please ? Thanks

Look for a local window and door shop near you. They will have multiple brands to select from - not as cheap as HD but there should be a better selection to choose from.

Several manufacturers make stock fire-rated doors, both flush and with molded hardboard facings to simulate stile & rail doors. A building supply store might have more options than a big box store.
