Adjustable 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. Hung in a 16 gauge galvanized adjustable Flex-Fit frame with a kerf for compression weatherstripping, it adjusts to fit the existing opening for a tight, secure and efficient replacement.
