CableCatches are used to secure cable(s) to any surface. The back of the Velcro surface has a pressure sensitive adhesive strip that will stick to racks, desks, counters, etc. For added security, or for non-smooth surfaces like wiring back boards, a staple or nail can be driven through the backing surface. Anytime the cable run needs to be modified, the Velcro cable catch is simply released and re-secured.  50 per pack.
