Proto J5260-02BLS Locking Socket Adapter 3/8 Inch

Product Description

The PROTO J5260-02BLS is a locking socket adapter designed for use with 3/8 inch drive ratchets, extensions, and socket sets. It features both a 3/8 inch male drive end and a 3/8 inch female drive end, making it a same-drive adapter suited for connecting tools and sockets in applications where a locking retention mechanism is required. The overall length is 2.125 inches. A hex key is included for engaging the locking function. This adapter is used by mechanics, HVAC technicians, plumbers, and electricians who need a secure socket connection during fastener work in tight or overhead installations.

The J5260-02BLS is appropriate for general mechanical and trade use wherever a 3/8 inch drive locking adapter is needed. The locking feature prevents accidental socket release during use, which is especially useful in confined spaces or when working at elevation. It fits standard 3/8 inch drive tool systems and is sold individually. This adapter is suited for professional shop and field use across HVAC, plumbing, electrical, and general mechanical service applications.

Engage the locking hex key before applying torque to prevent socket separation under load. Inspect the locking mechanism for wear before each use.
