This white grip clip, with a pre-installed steel nail, allows you to secure a single coax cable line by inserting the line into the clip and then nailing it into the desired location. The clip is made from high-impact plastic which keeps it from breaking. The hardened nails are suitable for hard woods, mortar and soft bricks. Use this clip rather than staples to reduce the risk of cutting the coax jacket. Each bag contains 100 clips.
