Frequently Asked Questions

What is the PROTO Socket Extension J4759 used for?

The PROTO Socket Extension J4759 is used to extend the reach of a 1/4" drive socket wrench or ratchet to access fasteners in tight or recessed areas. It is suitable for general mechanical and automotive applications where a standard socket cannot reach. The chrome finish resists corrosion.

What are the specifications of the PROTO Socket Extension J4759?

The PROTO Socket Extension J4759 has a 1/4" input drive size and a 1/4" output drive size, with a 2-inch overall length. It features a chrome finish, is not insulated, and does not include a locking mechanism. The manufacturer part number is J4759.

Where to buy the PROTO Socket Extension J4759 worldwide?

Contact us for availability and lead time; we supply genuine PROTO components to procurement teams globally.

How to select the correct socket extension for a 1/4" drive system?

To select the correct socket extension, match the input and output drive size to your ratchet and socket—both must be 1/4" for the J4759. Consider the required length (2 inches here) and whether you need insulation or a locking feature. For standard non-electrical work, a chrome finish like PROTO's is suitable.
