These three-piece self-affixing cable ties are supplied ready assembled and offer a simple and versatile method of bundling and fastening cables. The deep-hole anchor will easily push into blind holes with or without thread and attaches securely. The two-piece design enables the head of the tie to be oriented to the required position to ease assembly, while the disc on the top of the fir tree covers the hole and minimizes the ingress of water and debris.
