The flat side of the glazing strip is 5/8" wide the piece sticking down is 3/8" long. The gap for the glazing strip to fill in the aluminum frame is 3/8" with the glass in place; the window is in a manufactured home. The window is 27 1/4 X 28 1/2 so I will need a minimum of two (2) 60" sticks of glazing. Do you concur? Please reply with your stock number for the glaze strips.
