This strap filter wrench has been designed to remove oil filters up to 120mm and is particularly suited to accessing awkward areas. The wide nylon webbing strap provides a strong, non-marking grip and the twin head adjuster can be driven by a 1/2"D or 21mm Hex so the strap can be tightened by a ratchet, power bar or spanner. A simple, cost-effective solution for removing stubborn oil filters.
