How to Find it
When inquiring about Special-Lite doors, locate the Production Number Engraving on the hinge stile on the push side of the door. For doors over 65” tall, the mark is placed 60” up from the bottom of the door. If the door is under 65” tall, it is placed 7” down from the top of the door.
Note: Only Stile & Rail, Aluminum Flush, and FRP/Aluminum Hybrid Doors are engraved.
