Installation

This is a clamp ring window. Plan the location first, and confirm that the cutout fits between ribs and the structure. Because this is a larger window, spend extra time confirming that the surface is sufficiently flat for a uniform seal. Cut the opening to the listed cutout size. Set the window in the opening with the seal in place. Install the clamp ring and tighten evenly in a cross pattern until the seal compresses uniformly. Confirm slider movement, latch function, and screen operation before final tightening. Confirm drainage orientation and keep drainage channels clear.

Perfect for Promaster sliding door

I bought this window and installed it myself, using the instructions from VWD and a web page I found. The window came on time, very well packed, and included everything I needed but tools. This was the first one I ever did, and there were no surprises. Can't comment on customer service as I didn't need any. I would definitely buy from them again, fine quality and value.
