D-Line Safe-D Stag Clips can be first-fixed with their lower barbs gripping in pilot-holes, ready for second-fix cabling works. After cable(s) are inserted in the head section, installers simply push home the smooth head to give a tight fitment around either one or two cables. The Stag Clip design eliminates any need to ever handle the sharp barbs, while inserting cables is incredibly simple, and no screws are required. Stag Clips for use with 2x cables lock together when overlapped. Use Twin 8-10mm Stag Clips to hold 2x 8-10mm diameter cables.
