Rubber Grommets for 2" Panel Hole with 1 3/4" ID Made for 1/4" Thick Wall EPDM UV-Resistant Outdoor Firewall Wiring Grommet for Cable Hose Electrical Seal on RV Trailer Engine Bay (8 Pack)

These EPDM rubber grommets are made to fit a 2" (50.8mm) panel hole, with a 1-3/4" (44.5mm) center hole and a 1/4" (6.4mm) groove designed for 1/4" wall thickness. The locking groove securely snaps into sheet metal, plastic, or fiberglass panels without glue or hardware. Built from UV- and weather-resistant EPDM rubber, they’re perfect for outdoor or high-vibration environments like RVs, trailers, marine gear, or automotive firewalls. Use these heavy-duty grommets to protect wiring, cables, hoses, or tubing passing through sharp edges — ideal for DIY and shop projects.
