Its adjustable, trim-to-fit design ensures a snug, waterproof, and soundproof seal, preventing wire chafing and engine noise intrusion. Easy to install with just a 1 1/4" hole and a zip tie, it’s perfect for automotive, marine, and industrial applications where durable cable management is essential. ## Description Installation is as straightforward as it gets. You just need to drill a 1 1/4-inch hole on your firewall. Trim the tapered end of your boot's according to the tubing/wire bundle's thickness and then feed the tubing/wire bundle through the grommet end of the firewall boot. Fit the grommet to the newly drilled hall on your firewall. The grommet end should snugly fit on the hole. The last step will be to secure the wire bundle by wrapping a zip tie by the newly trimmed end of the boot. Take note to always double-check what's on the other side of the spot you are planning to drill into. There's a real risk of hitting the main wiring. Also, it is always advisable to drill a pilot hole on the firewall surface before proceeding. One of the best drill bits to use for this situation is a step drill bit. Scared of drilling holes through your firewall? Most of the time, there are preexisting holes on your firewall that you can use. Most of these holes have sturdy seals but depending on your car model, there may be unused firewall opening hidden behind insulation or even under the carpet. There could also be a preexisting wiring loom that passes through the firewall. It's can be feasible to use this avenue but you risk damaging the wires on the loom and besides, you can't use a firewall boot on an already overcrowded hole. The risk of pinching the wires is high in this method. The best solution is to use an opening you can install a universal firewall boot into and most of the time, this means drilling a hole through your firewall. The firewall insulation helps eliminate the noise coming from the engine. But once you drill a hole on the firewall and run wire through it, you're creating a weak link that will allow noise to pass through. That's why it's important to use a firewall boot that does not only prevent the wires from chaffing but also acts as soundproofing and weatherproofing seal. Review: Perfect for running wires through 2008 Silverado firewall - I needed to run some heavy gauge wire into my cab for my dc-to-dc charge controller and wanted something neat and water resistant. I found that GM left a perfect spot for installing this. I used a step bit and drilled the proper size hole(1-1/4”), filed the burrs and slipped this in. I cut the end for the size hole I needed for my wires and ran them through. I seem to recall reading some complaints about them being stiff. I did not find that to be the case. I am very pleased with the results. And I have plenty room if I ever need to run more wires.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for running wires through 2008 Silverado firewall *by M***K on 5 January 2022* I needed to run some heavy gauge wire into my cab for my dc-to-dc charge controller and wanted something neat and water resistant.
