SteelCrest BSL18X6SWHH Supply Vent Damper 18x6

Product Description

The SteelCrest BSL18X6SWHH is a slotted-face supply air vent with an integrated damper, designed for installation on walls or ceilings in residential and light commercial HVAC systems. Constructed from solid steel with a white powder-coat finish, it fits a standard 18 x 6 inch duct opening and presents a finished face size of 20 x 8 inches. The built-in damper allows airflow adjustment without a separate accessory. HVAC technicians and contractors use this grille on forced-air supply branches during new construction, renovation, or direct replacement of existing vents where a clean, modern slotted aesthetic is specified.

The BSL18X6SWHH suits residential forced-air supply applications and is well suited for remodel work where the existing duct opening is 18 x 6 inches. The 20 x 8 inch overall face covers rough drywall or plaster edges around the duct collar, making retrofit installation straightforward. The slotted face pattern is compatible with standard supply-side static pressure levels found in residential and light commercial ducted systems. HVAC installers and general contractors working on interior finish work are the primary installers of this product.
