Proto JSCR14 Combination Wrench 7/16 Inch Ratcheting

Product Description

The PROTO JSCR14 is a 7/16-inch combination wrench built for professional trade use in confined or elevated work environments. It features a 12-point ratcheting box end with a 15-degree head offset, allowing fastener engagement and rotation without fully repositioning the tool. The open end delivers standard single-pass engagement. Constructed from chrome-finished steel with a corrosion-resistant treatment, it measures 6.5 inches overall length and weighs 0.13 pounds. The tether-capable design makes it suitable for at-height work where dropped-tool hazards must be controlled. It meets ASME standards and carries a lifetime warranty.

This wrench is used in mechanical, HVAC, plumbing, and electrical trade applications wherever 7/16-inch fasteners appear in tight clearance conditions. The ratcheting box end reduces arc-swing requirements, making it effective in restricted panel spaces, equipment enclosures, and structural assemblies. The straight handle and 15-degree offset allow comfortable torque application in shallow work spaces. Tether-capable construction supports use on elevated platforms, rooftop equipment, and overhead installations where tool-drop prevention is required by safety programs or site policy.

Installation Notes

Install and remove fasteners with the ratcheting box end to minimize repositioning in confined spaces. Power down or de-energize equipment before working in electrical enclosures or panel areas. Attach a tether lanyard through the tether point before use at height in accordance with applicable site dropped-object prevention requirements. Inspect the ratchet mechanism for smooth engagement before each use.
