    • Description

      The Master Flow 6 in. x 6 in. x 4 in. Slant Top Insulated Register Box with Tabs provides a transition from round pipe or insulated flexible duct to air register or grill. It is insulated so there is no need to wrap after installations. The insulation also serves as a noise deadener and helps control condensation. It is designed for 4 in. round ducts. The slanted boot makes it easier to install near a sharply pitched roof. The built in flange can be used with Snap on Rails to make installation easier.

      • Designed for 4 in. ducts
      • 30 gauge
      • Can be installed with sheet metal screws (not included)
