36" x 11 1/2" Fully Framed Sash Window. Clear Glass. This deer blind window has slotted drain holes and a 3/4” flange around the entire window with pre-drilled holes for mounting. You’ll also enjoy two cabinet-style hinges that allow the window to swing up, a magnet-mounted on the frame to secure to the wall when open, and two swivel clips to fasten it closed. It can be made to hinge horizontally or vertically for gun or bow hunting. It is extremely quiet with little to no noise while opening and closing. NOTE: To allow for the window hinge correctly, the wall thickness should be no more than 2 inches. Instructions for mounting: 1. Add 1/8 inch to the height and length of the size window you purchased. Ex: A 36x11 1/2 window would need a rough opening of 36 1/8x11 5/8 for a proper fit. 2. Cut the hole needed. 3. Run a weatherproof caulk or use weather-stripping around the inside flange. 4. Place the window assembly through the opening and secure the outside wall using screws or bolts and nuts. 5. From inside the blind, raise the window up and secure a metal magnet holder on the wall to line up with the magnet on the window.
