required by dividing the measurement taken in
inches by 34”.
i. For example if the measurement was
68”, then 68” ÷ 34” = 2 so 2 lengths of
stack are required.
ii. For example if the measurement was
60”, then 60” ÷ 34” = 1.76 lengths of
stack are required. This would mean one
full length and a length measuring 26”
would be required. To obtain the 26”
length you can either
iii. Special order a piece of stack the length
required
iv. Cut a standard length of stack to fit. If
you cut a length of stack to fit, measure
the length from the bead of the stack
and cut off the top crimped end.
