Proto J3070B Open End Wrench 1-1/2 X 1-5/8 in Double End

Product Description

The PROTO J3070B is a double-ended open end wrench designed for heavy-duty fastener work in demanding trade environments. It features a 15-degree head angle that improves access in tight or obstructed spaces, allowing technicians to reposition the wrench with minimal swing arc. Built from steel with a black finish, this wrench is sized at 1-1/2 x 1-5/8 inches across its two open ends. It is appropriate for HVAC, plumbing, pipefitting, and mechanical maintenance tasks where large-diameter fasteners, unions, or fittings require controlled torque without a ratcheting mechanism.

This wrench is suited for residential and commercial service work involving large hex fasteners, flange bolts, gas line unions, equipment mounting hardware, and similar applications. The dual-end configuration provides two working sizes in a single tool, reducing the number of wrenches needed on the job. It is well suited for equipment rooms, mechanical spaces, and any environment where large fasteners are routinely accessed in close quarters.

Key Features

• Double-ended design provides 1-1/2 inch and 1-5/8 inch opening sizes in one tool
• 15-degree head angle improves clearance in confined or obstructed fastener locations
• Steel construction for durability in heavy-duty trade applications
• Black finish provides corrosion resistance and reduces glare in the field
• Backed by a lifetime warranty from PROTO

Compatibility

Designed as a general-purpose open end wrench for 1-1/2 inch and 1-5/8 inch hex fasteners commonly found in HVAC, plumbing, pipefitting, and mechanical maintenance applications.

Installation Notes

This wrench is a hand tool requiring no power source or installation. Ensure the correct end is fully seated on the fastener before applying torque to prevent rounding. Use appropriate personal protective equipment when working on pressurized systems, and always isolate or de-energize equipment before servicing mechanical connections. Follow applicable IFGC, IPC, or NEC requirements based on the system being serviced.
