Southwark Metal 27R_4X14X6 Duct Boot 4x14x6 Straight

Product Description

The SOUTHWARK METAL 27R_4X14X6 is a straight rectangular-to-round sheet metal duct boot designed for connecting rectangular duct runs to round collar register openings in residential and light commercial HVAC air distribution systems. Fabricated from hot-dipped galvanized steel, this boot transitions a 4 x 14 inch rectangular face to a 6 inch round collar. It is sized for standard floor, wall, or ceiling register applications and is built to ACCA and SMACNA standards. Licensed HVAC technicians and sheet metal contractors install this fitting as part of supply-air distribution trunk and branch layouts.

This duct boot fits into supply-air branch runs where a rectangular register opening meets a round branch duct. The 4 x 14 inch face accommodates a standard register grille, while the 6 inch round collar connects to a matching round branch duct or flexible duct. Typical installations include residential forced-air systems with floor or wall register drops, as well as light commercial applications requiring SMACNA-compliant sheet metal fittings.

Installation Notes
