- TIGHT FIT FOR A SOUNDPROOF AND WATERPROOF SEAL - Don't settle on firewall boots that won't fit the wire bundle snuggly, allowing noises from the engine to pass through. These universal firewall boot's grommets have sturdy and thick collars that will tightly fit on the drilled hole. The universal-fit ensures that the wire bundles are tight no matter how thick or thin they are.
- FITS A WIDE RANGE OF WIRE BUNDLE THICKNESS - This universal automotive grommet can accommodate anywhere from 3/8-inch to 1-inch bundles. You won't need to buy different-sized grommets for different applications, just trim the boot according to the bundle's thickness and secure it with a zip tie. It's simple, convenient, and most importantly, effective.
- EASY, NO FUSS UNIVERSAL FIREWALL BOOT INSTALLATION - All you need is a 1 1/4-inch hole for installation, scissors or utility knife to cut the boot's tapered end according to the thickness of the wire bundle. From there, all you need to do is install the firewall boot on the drilled hole and run the wire through it.

## Questions & Answers

**Q: Can the large end ID be stretched to 1.5"?**
A: Hi Keith, this item is made to accept up to 1" wire bundles or hose etc. And will fit into holes drilled to fit the outside diameter of the grommet you are using. Now as for enlarging the large end to accommodate a 1.5" bundle I couldn't tell you. I would imagine it could be stretched a bit but then the question would be if it will stay securely in the hole, you're inserting it into.
