Description
The Proto J1187M-A is a 19 mm x 21 mm offset reversible 12-point ratcheting double box wrench in metric sizes. The manufacturer states that the full polish finish provides corrosion resistance and easy-to-clean surfaces, and that the built-in retaining ring in each ratchet wheel adds speed and convenience for greater accessibility.
Per the manufacturer, the 25° offset box end helps keep the shank clear of obstructions and the reversing switch lever allows easy changes in turning direction; the 12-point box ends allow fine indexing and fit 4, 6 and 12-point fasteners, and the wrench self-aligns with the fastener. Its shorter length gives access to confined workspaces. Sold as a single wrench.
