Seal-tite 3516-410 Sheet Metal Boot Frame 10x4 in 26 Gauge

Product Description

The SEAL-TITE 3516-410 is a galvanized sheet metal boot frame used in residential and light commercial HVAC duct systems. It provides the structural opening that connects a round or rectangular duct run to a floor, wall, or ceiling register boot. Fabricated from 26-gauge galvanized metal, this frame measures 10 inches in length by 4 inches in width and is designed for 16-inch on-center framing layouts. HVAC installers and sheet metal contractors rely on this type of frame to create a clean, code-compliant transition point where the supply or return boot seats against the subfloor or wall cavity.

This boot frame is suited for new construction and retrofit duct installations in residential and light commercial settings. It is sized to work within standard 16-inch on-center stud and joist framing, making it a practical fit for typical wood-frame construction. The galvanized finish resists corrosion in both conditioned and unconditioned spaces such as crawlspaces and basements. HVAC technicians and sheet metal mechanics will find this frame applicable to forced-air supply and return duct termination points throughout a structure.
