Builders Best rv28-8 8 Inch Snap-in Duct Adapter

Product Description

The BUILDERS BEST rv28-8 is an 8-inch snap-in duct adapter designed to create a secure, leak-resistant connection between flexible or rigid ducting and compatible vent hoods. Molded from UV-protected, impact-resistant polymer resin, this adapter is built for long-term performance in outdoor and attic installations where sun exposure and temperature swings are constant. The patented snap-in design eliminates the loose joints that lead to moisture infiltration and energy loss. HVAC technicians and installation crews use this adapter when terminating ductwork at roof or eave vent hood assemblies.

This adapter is intended for use with 8-inch ducting in residential ventilation applications, including kitchen exhaust, bathroom exhaust, and range hood duct runs that terminate through the roof or eave. It pairs directly with the RV28 Roof Vent Hood and the RVL28 Roof Vent Hood, as well as the SV28 Eave Vent Hood. The snap-in fit simplifies field installation and reduces the chance of improper seating during rough-in work. Five sizes are available across the product line to cover 4-inch, 5-inch, 6-inch, 7-inch, and 8-inch duct diameters.

Installation Notes

Installation is typically performed by HVAC technicians or ventilation contractors during duct termination at the roof or eave. Power down any associated exhaust fan before beginning work.
