90-Minute RSP Series Fire Doors

RSP Series Doors are commonly referred to as the RF Series Steel Edge Fire Doors. These doors can withstand a 90 minute fire rating when hung in a split steel frame and are rated with a neutral pressure label. The hinge and strike locations manufactured into the door match Therma-Tru’s standard Full Size, or Book Size, specifications. They utilize a 5/8″ radius corner hinge with a Z pattern. Fire doors should always be self-latching with either self-closing hinges or a reinforced door slab with a door closer.


Panel Types

There are three 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. Finally is a flat panel with shaker sticking around the panel.

Door Dimensions

RF series doors fit in Reeb’s RSP Split Steel Frame. These frames accomodate full width doors with mortised hinge preps and door heights of 79-1/4”, 83-1/4” and 95-1/4” before sweep. This fire door can be cut down by Reeb up to 3”, from the bottom only. If any door is cut down, the bore and hinge locations will shift down with the cut and cannot be adjusted due to the steel skin and edge.

Rough Openings

Rough openings vary depending on the sill type and the door width. Sill options include a standard sill, no sill, and a public access (ADA) sill for both inswing and outswing units. Ensure the closure package jamb depth and sill application match what is needed in the field. Below are the minimum drywall rough openings. For 7′ doors, add 4″ to the height dimensions and for 8′ doors, add 16″ to the height dimension.
