90-Minute Therma-Tru Steel Edge Doors

Note: Reeb no longer offers Therma-Tru steel-edge doors. This information will remain available as a reference.

Therma-Tru’s SE Series doors are Steel Edge (SE) 90-minute steel doors with specific hinge and strike locations. These doors can accommodate a double bore when necessary. These doors are constructed with 24-gauge steel edges and are tested to withstand at least 90 minutes of fire exposure at temperatures that reach more than 1,700 degrees Fahrenheit. They utilize a 1/4″ radius corner hinge with a c-hole pattern. These units are suitable for a minimum of 4” wall depth and up to 8-1/2″ and are hung on a split steel frame.

Panel Types

There are two panel types. First is a raised panel with a triple shadowed embossment around the panel referred to as High Definition. Next is a raised panel with a standard sticking around the panel referred to as Standard Definition.

Door Dimensions

SE series doors fit in Therma-Tru’s Split Steel Frame. These frames accomodate slightly undersized doors with hinge, strike, and deadbolt preps pre-machined with door heights of 78-15/16” and 82-15/16” before sweep. The deadbolt bore is 5-1/2″ on center as a standard. This fire door can be cut down by Reeb, up to 4”, from the bottom only. If any door is cut down, the bore, deadbolt, and hinge locations will shift down with the cut and cannot be adjusted due to the steel skin and edge.

Door Height Top of Door to Top of Each Hinge Top of Door to Center of Bore
6/8 8-1/4” 38” 67-3/4” 43-31/32″
7/0 8-1/4” 40” 71-3/4” 47-31/32”

Measurements above are from top of door to Top of Hinges. 4” on-center double bore is available.
