Comments

• To calculate the length of the interlock, subtract 3-13/16 in. from the width of the double-hung frame or the height of the slide-by window frame. For example, if your double-hung is 24 in. wide, trim the interlock to 20-3/16 in. (24.00 - 3.812 = 20.188).
• In monumental single-hung units, the rigid interlock extension is routed off the last 1¼ in. of each end.
