Vent Fan Install Frame
Our vent fan frames are designed to help you install your vent fan or rooftop AC unit through thin sheet metal. Typically, when installing these products, the single layer of sheet metal is not rigid enough to accommodate sheet metal screws and often deforms around the opening. These frames reinforce the cutout as well as provide an extra flange on the inside to attach framing and ceiling material to around the opening.
Inside dimension of frame is 14 1/8"x 14 1/8"
Includes wiring hole with grommet.
