My hockey puck peel board. I used a 2x4 mounted horizontally to hold the dual pane window up, countersunk mounting screws in the pucks which set the glass 1.5” away from the wall, and gave me a place to mount the drip rail which directs the soapy water into a catch bucket. It’s 66” wide x 42” high. Would be good if it was a little bit taller but the price was right and it works.
