Step 1
Attach the clamp to the tie wrap by holding the clamp with the loop side on the bottom and sliding the tie wrap through
the box-shaped channel above the clamp (see the following figure).
One side of the tie wrap has evenly spaced ridges and the other is smooth. Be sure the ridged side is face up and that you
slide it through the open side of the channel. You will hear a click as the tie slides through—it moves in one direction
only. To remove the tie wrap from the clamp, push the lever on the closed side of the box-shaped channel and slide out
the tie wrap.
