Apolo PVC and Metal Conduit Saddles are a basic clamp designed to fix tubing and condiut to concrete and other masonry substrates. These handy clips are also ideal for corrugated pipes, cables and PVC pipe installations into concrete, stone, concrete block and solid brick (for use with ICCONS Gas Tools). The Metal Condiut Saddle (GTMT25) is also equipped with a Fire Rated Approval.
