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. ## Frequently Bought Together - TonGass (3 Pack) Universal Firewall Boot - Safe and Convenient Firewall Grommet Kit Can Accommodate 3/8 Inch to 1 Inch Wire Bundles - Rubber Grommets Wire Protection,Closed Rubber Grommet,Firewall Solid Closed Hole,Firewall Plug Grommet Synthetic Wire Protection Hole Grommets,for Drill Hole Wire Electrical Appliance Plumbing - Vrupin 188 Pieces Closed Rubber Grommet Firewall Solid Closed Hole Plug Assortment Kit for Wire Electrical Appliance Plumbing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/270546011-tongass-3-pack-universal-firewall-boot-safe-and-convenient-firewall](https://www.desertcart.no/products/270546011-tongass-3-pack-universal-firewall-boot-safe-and-convenient-firewall) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
