uxcell 100pcs 8mm Mounted Cable Hose Snap Bushing Grommet Protector Black

Today we're going to review and install the Spectro Snap Bushing, part number SWC8055 Note, the snap bushing is available in two sizes: the 7/16 inside diameter and a 9/16 inside diameter, part number SWC8057 Here's what our Spectro snap bushing looks like This is a nylon bushing that will help protect our wiring as it passes through our pre-drilled hole Typically that hole is drilled into sheet metal like a firewall The raw edges of the metal can chafe or dig into the wiring or even an air line, and the snap bushing will protect it Once the snap bushing is slid through your pre-drilled hole, the locks here will help hold it in place and the face of the grommet will be on the other side of the firewall, so we'll have part of the grommet on each side holding it in position When drilling it out, you're going to open it up to approximately a 9/16 hole
