20 x 20 General Purpose Access Door with Gasket

The BA-AHD is designed for a quick and easy installation on non-rated vertical and horizontal surfaces made of drywall or any other type of material. Its rounded mitered corners, concealed pin hinge and 3/8 return all around the door make it the sturdiest door on the market. The AHD prevents sagging as compared to flat door panels and requires fewer locks.
