Proto J5260-03L 3/8 in Drive Socket Extension 3 in

Product Description

The PROTO J5260-03L is a 3/8 inch drive standard socket extension designed for use with 3/8 inch drive ratchets, torque wrenches, and impact tools. With an overall length of 3 inches, this extension provides moderate reach for fasteners in confined or recessed locations. It is a core hand-tool component found in professional toolboxes across mechanical, HVAC, plumbing, and electrical trades. The compact length suits tight-clearance work where a full-length extension would be impractical, and the standard drive size makes it compatible with the widest range of 3/8 inch drive sockets and accessories.

This socket extension is suited for general mechanical and trade applications where 3/8 inch drive tools are the preferred choice. Common uses include equipment service, panel work, fixture installation, and component replacement tasks encountered in residential and light commercial settings. The 3 inch overall length bridges the gap between a short extension and a mid-length bar, making it a frequently reached-for piece in a socket set.

Key Features

• 3/8 inch drive size for broad compatibility with standard socket sets
• 3 inch overall length for moderate reach in confined spaces
• Standard extension profile fits ratchets, breaker bars, and torque wrenches
• Lightweight at 0.21 pounds for reduced hand fatigue during extended use

Compatibility

Designed as a standard-fitment extension for use with 3/8 inch drive sockets, ratchets, and torque wrenches in professional hand-tool applications.

Installation Notes

Insert the male end of the extension into the 3/8 inch drive square of the ratchet or wrench, then seat the socket onto the female end before applying torque. Inspect the extension and drive square for wear or cracks before use. Do not use extension bars to increase torque beyond the rated capacity of the socket or fastener being driven.
