Protective wire loom helps organize and shield cable bundles on boats, trailers and RVs. Ancor supplies black loom rolls in several nominal tubing diameters, including 3/8, 1/2, 3/4 and 1 inch. These products share a 100-foot roll length but have different MPNs and potentially different material specifications; measure your wiring and verify the actual product construction before replacing one part with another.

Important MPN distinction: Ancor offers wire-management materials including spiral wrap, split loom and different specialty formulations. Matching diameter and colour do not establish that two numbered rolls have the same construction or application rating. Where heat resistance, self-extinguishing properties or other performance approvals matter, use the exact manufacturer specifications for the ordered MPN.
Plan wiring protection before cutting the loom
- Check the cable bundle: Measure the wiring and connector diameters, leaving sufficient room for movement, installation and service access.
- Check the required covering style: Some installations need split conduit with wire exits along a harness, while others may specify spiral wrap or a different type of sleeve. Verify which design the original installation requires.
- Measure the route: Include cable bends and protected transitions, rather than the straight-line distance only.
- Check the surroundings: Follow the vehicle or boat manufacturer's electrical guidance for abrasion, heat, water, fuel vapours, flame rating and wiring segregation. An unverified loom rating should never be used to justify installation next to an exhaust or other hot part.
- Secure the harness: Use suitable tie mounts and fasteners without crushing the conduit or damaging conductors. Protect sharp edges and panel openings separately.
Common wire loom questions
Is 452385 interchangeable with 453386? Both catalog records list 3/8-inch black loom in 100-foot rolls, but they are separate Ancor MPNs. Confirm material specifications and intended installation before substituting.
Can one 100-foot roll be cut into shorter lengths? These are bulk-length products. Cut only as appropriate for the installation and manufacturer's instructions, leaving sufficient protection at each endpoint.
Does the loom include wire ties? The listed 452385, 452505, 453755 and 453905 catalog records explicitly say no tape or ties are included. Check individual package contents for any other MPN rather than assuming fasteners are supplied.
