It bundles two 3/8" air brake hoses and a 7-way electrical cable into one neat line, shielding them from abrasion, cuts, and tangling. The high-memory plastic stays flexible down to -40°F and resists UV damage, helping extend the life of air lines and wiring. It is sold by the foot from a 66-foot roll, so you can order just the length you need for a repair or custom installation.
