A universal rubber grommet designed to seal and clean up the area where wiring and hoses pass through the firewall. The trimmable boot accepts cables, wires, or hoses from 3/16 inch up to 1 inch in diameter, helping keep dust, water, and fumes out of the cabin. Includes a polished stainless steel bezel and stainless hardware for a clean, finished look on any custom build or restoration.
