SteelCrest BSL20X6SWHH Supply Vent Damper 20x6

Product Description

The SteelCrest BSL20X6SWHH is a slotted decorative supply vent with an integrated damper, designed for wall and ceiling installation in residential and light commercial HVAC systems. Constructed from solid steel with a white powder-coat finish, it fits a 20 x 6 inch duct opening and installs with an overall finished face size of 22 x 8 inches. The built-in damper allows the installer to adjust airflow volume at the register without additional hardware. This vent is a direct-replacement unit suited for new construction and remodel applications where a clean, modern slot-style grille profile is specified.

This supply vent is used in forced-air HVAC systems where the supply duct terminates at a wall or ceiling surface. The 20 x 6 inch duct size is common in residential trunk-and-branch layouts and light commercial buildouts. The finished face dimensions of 22 x 8 inches cover the rough opening cleanly, making it well suited for both new-install and drop-in replacement work where the existing duct collar is already sized to match.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified contractor. Power down the air handler or furnace at the disconnect before beginning work. Confirm the duct collar dimensions match the 20 x 6 inch opening before securing the grille to the wall or ceiling surface. Follow local mechanical codes and manufacturer fastener guidance for the mounting substrate type.
