Appearance alone is insufficient

A door’s appearance does not establish fire performance. Review model-specific test and classification documents alongside dimensions and intended use.

The complete assembly

Frames, leaves, seals, hinges and closers should follow the approved assembly details. Confirm the suitability of hardware substitutions with the manufacturer and project professional.

Installation and follow-up

Installation should follow project requirements, and obstructions to closing should be addressed. Request current model documentation and maintenance instructions during quotation.
