Six of these 4 in. cable ties are included with the 7363 Enclosure Supply Kit and 10581 ET Shipping Kit. The cable ties are constructed from a flexible, nylon material. A connection is made by pulling the tapered end through the locking end, thus forming a loop. The free end is pulled tight to secure the cables, then trimmed back to the locking end. Once attached, the cable tie must be cut to be removed.
