These grommets are made with high quality materials and manufacturing processes to allow a precision fit and durability. You simply slide the two parts together, then fasten them in to your firewall or sheet metal to act as a protective cable or hose grommet, even after those cables and hoses have already been installed.
This eases the pain of retroactively protecting the cables and hoses you've run through the firewall of your hot rod by assembling without having to remove the cables or hoses from the hole.
Smooth internal radiuses provide support without cutting in to your insulations and sheathing. Designed for #8 sized screws, with up to 1/4" hex head using a normal 1/4" socket or drive bit.
