Note: Reeb no longer offers Therma-Tru steel-edge doors. This information will remain available as a reference.
The Therma-Tru Inswing fire sill is used with the 90-minute Therma-Tru steel edge doors in the Therma-Tru split steel frames. An extender is included with the closure package so the sill matches the desired frame depth.
