Proto J5464 1/2 in Drive Socket Extension 20 in

Product Description

The PROTO J5464 is a 1/2 inch drive standard socket extension with a 20 inch overall length, built for professional use in trade and industrial applications. Socket extensions in this drive size are a staple in mechanical, HVAC, plumbing, and electrical work where fasteners are recessed or otherwise inaccessible with a short tool. The 20 inch length provides significant reach into tight spaces such as equipment panels, mechanical chases, and confined compartments. At 1.91 pounds, the J5464 carries the heft expected of a full-length professional-grade extension. Licensed tradespeople and journeymen mechanics rely on tools like this for both installation and service work.

The J5464 fits into standard 1/2 inch drive tool setups used across HVAC equipment service, pipefitting, electrical panel work, and general mechanical maintenance. The 20 inch overall length suits applications where standard short extensions cannot reach — including deep fasteners on air handlers, compressors, pump housings, and structural mechanical assemblies. This extension works with any 1/2 inch drive ratchet, torque wrench, or impact driver using the same drive size.

Key Features

• 1/2 inch drive size compatible with standard professional ratchets and torque wrenches
• 20 inch overall length for deep-reach fastener access
• Weighs 1.91 pounds, reflecting solid construction for trade use
• Single-piece packaging for straightforward tool inventory and procurement

Compatibility

Designed for use with any 1/2 inch drive ratchet, breaker bar, torque wrench, or impact driver conforming to standard 1/2 inch square drive dimensions.

Installation Notes

A licensed mechanic or qualified tradesperson should select the appropriate torque wrench or ratchet before use to avoid fastener damage. Ensure the extension is fully seated in both the drive tool and the socket before applying torque. Inspect the drive end and socket end for wear or deformation before each use. Do not use with tools that exceed the rated drive size.
