Fire Rated Doors 1 3/8" Thick www.apexdoors.net
One product we distribute that always gets a reaction from out customer of "I didn't know you could do that" is in regards to the custom 1 3/8" thick labeled door instead of the more common 1 3/4" thick labeled metal door.
In the commercial world, a 1 3/8" thick door is used to solve a common retrofit problem. If you want to change the swing of a door without changing out the frame, you can elect to do so with this 1 3/8" door that fits in the 1 9/16" frame rabbet using a full surface continuous hinge for an easy swing.
A 1 3/8" labeled door must meet the same requirements as a 1 3/4" door. It must have a minimum number or approved hinges, be self closing & self latching. Distributing for one of the very few manufacturers with the ability to put labels on 1 3/8" thick doors lets us stand out in the crowd. A solution for re-using a frame, rather then tearing out and installing completely new saving you time and money.
