A rectangular lite is 42 in. wide and 78 in. high. Glazing stop is needed around all four sides, and the cut list adds 10 percent waste. What stop length should be carried?
Correct Answer
D) 264 in.
Perimeter is 2 x (42 + 78) = 240 in. Adding 10 percent waste gives 240 x 1.10 = 264 in. Other choices omit one side, omit waste, or add too much allowance.
