This category covers finishers of fire doors. Finishers are identified as distributors in the steel door industry and machiners in the wood door industry.

Finishers receive fire doors from the primary manufacturer. These fire doors have a unique marking signifying the door was manufactured in compliance with UL's Follow-Up Service requirements. The finisher may modify the fire door to satisfy site-specific requirements for items such as vision panels and hardware.
