Gray identifying stripe runs the length of the slit tubing. Temperature rating of -40° to 300° F, (-40° to 149° C). Full length slit makes it easy to insert wires or branch out circuits. 1/2 Inch diameter is suitable for around size 14 gauge wires, or for covering up to 2 gauge battery cable. Corrugated outer wall adds strength and flexibility, while keeping the slit closed when bent around tight corners. Excellent crush resistance and resistance to fuel and chemicals.
