Carbon Fiber Snap Grommet

The HG Manufacturing Snap Grommets provide the ability to retroactively install a protective grommet around your electrical cabling, hoses, or whatever may be passing through a firewall or other sheet metal. The polycarbonate-carbon fiber two-piece design snaps together around the pre-installed cables/hoses and fastens to sheet metal using your favorite style of #8 size screws (I know you self-tapper people are out there!).  This comes in Single Hole sizes 1", 1-1/4", 1-1/2", and 1-3/4". Dual Hole sizes are Dual 3/4" and Dual 1" https://hgmanufacturing.net/
