Compression-Fit makes installing literally as easy as 1-2-3!
- Cut the header channel to fit inside the top of your window frame and secure the channel in place.
- Squeeze the compression sides in to insert the top of the window into the header channel, then continue pressing the sides in from top to bottom as you push it in place.
- Drill a 3/32″hole on each side in front of the window about 1/3 of the way up from the sill and insert the blocking pins.
