Product Description

The PROTO JSCR30 is a ratcheting combination wrench built for professional trade use in mechanical, HVAC, plumbing, and electrical service applications. It features a 15/16 inch head size with a 15-degree offset angle and a 12-3/4 inch overall length, giving technicians the reach and clearance needed in tight spaces. The 12-point box end ratchets for efficient fastener work without repositioning the wrench on every stroke. Constructed from steel with a chrome finish, the JSCR30 meets ASME standards and carries a lifetime warranty. It is also tether capable, making it suitable for elevated or overhead work environments where dropped tools are a safety concern.
