Find Fire-Rated Labels
Nov 16, 2018

How do you know if your door is fire-rated?  Look for the UL or WH fire label.  At times, the label is easily found, and at others it can be quite difficult to locate.  Below are some helpful tips for finding the fire label.

  • Start by looking on the hinge side of the door.  See the pictures below for various UL and Warnock Hersey (WH) labels that you may see.  The critical component to look for is the circled “UL” or “WH.”

  • On wood doors, the fire label can be on the hinge side or top of the door.

  • Over time, the label may get painted over , so check carefully for any raised surfaces.

  • The label may also be located on the top or bottom of the door.

  • Some labels are embossed in the frame, so be sure to feel for any texturing/raised surfaces.
