Builders Best 110812a Mini Louver Hood 4 Inch White

Product Description

The BUILDERS BEST 110812a is a mini louver hood designed for residential and light commercial ventilation duct terminations. It fits a 3 inch male collar and accommodates duct openings in the 3 inch to 4 inch diameter range. The hood is constructed from polypropylene molded plastic, offering resistance to moisture and UV exposure in exterior applications. A fixed 1/4 inch x 1/4 inch molded louver grid is built into the face of the hood, providing a barrier against pest intrusion without restricting normal exhaust airflow. Four mounting holes are integrated into the flange for secure wall attachment. This hood is installed by HVAC technicians, plumbers, and general contractors during dryer vent, bathroom exhaust, or range hood duct rough-in and termination work.

The 110812a is suited for exterior wall termination of small-diameter exhaust duct systems in residential construction and renovation projects. It is commonly used to terminate dryer exhaust vents, bathroom fan ducts, and similar low-pressure ventilation runs where a 3 inch male collar connection is required. The white finish blends with standard exterior surfaces. The molded fixed louver design requires no moving parts, reducing maintenance over the life of the installation.

Installation Notes

Installation is typically performed by HVAC technicians or contractors during new construction or duct system retrofits. Shut down any connected exhaust fan or appliance before installation. Fasten the hood to the exterior wall through the four provided mounting holes and seal the perimeter with an appropriate exterior-grade caulk to prevent air and moisture infiltration. Verify local building codes for exhaust termination clearances and hood placement requirements before installation.
