Our Steel-Lite™ interior hollow metal doors with slip-on frames are engineered to retrofit 2x4 wood stud drywall openings built with two layers of 5/8" drywall on each side (≈ 7-1/8" overall wall thickness). The slip-on frame sleeves over the finished wall for a clean, precise fit — making these doors ideal for heavy-duty interior renovations.
These retrofit assemblies are ideal for schools, medical facilities, government buildings, and multifamily projects where 2x4 drywall partitions with multiple layers require a durable, inspection-ready replacement door system.
