Buying guide: best split wire loom

Diameter: match the bundle

Diameter decides what fits inside. The CrocSee loom is 1 inch, the Alex Tech looms are 1/2 and 1/4 inch, and the YesBes looms cover 3/8 inch alone or 3/8, 1/2 and 3/4 inch in one listing. A split loom closes on itself once loaded, so the diameter should fit the bundle with room to close. For the right size, see our heat shrink tubing size guide.

Length: 25 ft or 120 ft

Length decides how many runs one buy covers. The Alex Tech looms and the CrocSee loom are 25 ft, the YesBes 3-size listing is 50 ft, and the YesBes 3/8 inch loom is 120 ft. Cut the length to the size you want, then find the slit and put the wire in, per the YesBes listings.

Temperature range and material

Temperature range decides where the loom can live. The Alex Tech 1/4 inch loom is rated -103 to 257 F, the 1/2 inch loom -94 to 257 F, the CrocSee loom -22 to 221 F, and the YesBes looms -40 to 200 F. The YesBes looms are polyethylene, the CrocSee loom is flame-retardant polypropylene, and the Alex Tech 1/2 inch loom is 100% new polyethylene. The YesBes listings say the loom can be used under-hood, but away from the exhaust manifold.

Warranty and safety listings

Only the CrocSee loom states a warranty term, a 1-year warranty. The YesBes listings give a warranty description of “use only”, which is not a warranty term. Safety points go to the Alex Tech 1/4 inch loom for its UL Recognized listing and to the CrocSee loom for flame-retardant material.

Garage Fit Check

• The CrocSee loom is 1 inch in diameter and 25 ft long, so measure the bundle before ordering.
• The YesBes 3/8 inch loom is 120 ft, so it covers long runs in one buy, while the 25 ft looms suit shorter jobs.
• Under-hood use needs clearance from the exhaust manifold, per the YesBes listings.
• The CrocSee loom comes with an insertion tool, so feeding wires through the slit is easier.
• All 5 looms are split, so wires go in without disconnecting the run.

FAQ: garage tools

What is the best split wire loom?

It depends on the bundle. CrocSee leads on diameter and warranty with a 1 inch flame-retardant loom and a 1-year warranty, Alex Tech leads on temperature range, and YesBes leads on length. This guide scores all 5, and the CrocSee loom ranks at the top.

What size split wire loom do I need?

Match the diameter to the bundle. The looms here run from 1/4 inch to 1 inch, and the YesBes 3-size listing covers 3/8, 1/2 and 3/4 inch in one buy. A loom that closes on itself once loaded fits the bundle best.

Can split wire loom go under the hood?

The YesBes listings say the loom can be used under-hood in a car, but away from the exhaust manifold. Its temperature range is -40 to 200 F, so keep it clear of hot parts.

Is split wire loom flame retardant?

Only the CrocSee loom states flame-retardant material, thick polypropylene rated -22 to 221 F. The Alex Tech 1/4 inch loom states a melt temperature of 446 F, and the other listings state no flame-retardant material.

Do split wire looms come with a warranty?

Only the CrocSee loom states one: a 1-year warranty. The YesBes listings give a warranty description of “use only”, and the Alex Tech listings state no warranty term.
