Step 1: Measure width

Measure the width of the strap in the middle (Figure 1), not on the ends where it is attached to the frame. If it measures approximately 1 3/4", order 2" vinyl strap. If it measures approximately 1 1/4", order 1 1/2" vinyl strap.

Step 2A: Measure Length-Single Wrap

Single-wrap method. Place the tape measure at one hole and measure over the frame to the hole on the opposite bar following the placement of the strap. (Figure 2)

Step 2B: Measure Length-double Wrap

Double-wrap method. Place the tape measure at one hole and wrap the tape around the bar once (Figure 3). Let out the tape to the other side and wrap once around that bar following the placement of the strap.

Step 2C: Measure Length-Clip method

Metal clips. Place the tape measure where the strap attaches to the clip on one bar. Measure to the corresponding clip on the opposite bar.

Step 3: Calculate the Amount

Reduce the length of the strap measurement by 10%.
Examples:
23" length x .90 = 20.7" to order
29" length x .90 = 26.1" to order
Multiply the “to order” amount by the number of straps
for the total amount of vinyl strap to order.
