The standard steel firedoors are available in all sorts of sizes. Our
lab area has 36"x 78" doors, double 36x78" with no mullion, double
36x78" with the divider mullion, double 42"x84" with no divider, and a
monster 42"x96" double with no divider. I've seen 48" widths as well.

The new price on these is horrible. I don't have current prices but I'd
expect numbers well above $1000 for a double door setup. They are
sometimes available at one of the used/seconds building materials places
for much more reasonable prices. I have several places locally
(Minnesota) that stock them used.

If you buy used, you should know that the door AND the frame are
considered one unit as far as meeting fire code. For hobbyist level or
small commercial where the door is not used as a fire block, this is not
an issue.

You might be in for a shock when you try and install these sorts of
doors. We had to take several of these off the hinges to move equipment.
Each door took 3 of us to remove or install, they are that heavy and
clumsy.

I'm still working on the neverending project of moving my stock rack
to the unheated warehouse side of my shop. I will have to cut a
doorway through the brick wall. I'm thinking at least a 36" single
door. Also considering a double wide door I could get the forklift
through. top of the roll cage is 7'3" (87") Since a std door is
only 6'8" I need extra tall. anyone have a door like this in their
shop or where you work? Are they available?

Thank You,
