The VIM Tools RFW100 is a ratcheting line wrench engineered for servicing brake, hydraulic, gas, refrigeration and oxygen sensor lines in tight or obstructed areas. Its spring loaded jaw opens when rotated in the opposite direction, allowing smooth ratcheting without removing the wrench from the fastener. The quick clamp feature automatically secures the wrench upon contact, enabling one handed operation. Serrated jaws provide six point gripping power and prevent fastener rounding, even on damaged fittings. With wide opening jaws and a compact design, the RFW100 delivers exceptional access and control for professional technicians.
