Encapsulating Flex-Fit Frame with Kerf
The Rusco insulated steel door delivers all three marks of peak steel door performance: energy efficiency, security and durability. Two 18 or 22 gauge steel skins are locked together by a vinyl V-groove interlock around a rigid polyurethane core, so the skins never touch and there is no glue to fail. The encapsulating Flex-Fit frame wraps the existing head and both jambs in 16 gauge galvanized steel, covering the old frame completely for a clean, fully finished replacement, with a kerf for compression weatherstripping.
