1/2 Inch Blue Wire Loom is a practical and decorative wire covering designed to protect electrical wire and cables from damage that can lead to short circuits. Used in automotive electrical systems and other electrical applications. Made from durable polyethylene. The corrugated ribbed tubing provides a high degree of flexibility and crush resistance and your wires can easily be inserted into the loom due to it's full length slit design. We recommend securing your blue wire loom with either blue cable ties or nylon cable clamps.
