This RV-style door has an aluminum frame and fiberglass insert, as well as weather-stripping around the frame and drain holes in the bottom of the door to prevent leaking. It also has a 5/8” flange around the frame with pre-drilled holes for mounting to your exterior wall. Doors come in green but can be painted to match your existing color. Note*: Blind Doors require an additional shipping fee. (Rough Opening: 24 3/8 x 60 3/8)
