The Wright Tool 3405 is a 3/8-inch drive socket extension at 6-inch length, sized for daily mechanical service where the socket needs to clear an obstruction.
Wright Tool has forged drive extensions in Barberton, Ohio since 1927 from U.S. steel. The 6-inch length is the most-used extension size in automotive bays — long enough to clear most obstructions, short enough to retain torque feel.
Use the 3405 for spark plug service, valve cover bolts, intake manifold fasteners, and any spot where a socket needs 6 inches of standoff. Lifetime warranty on Wright manufacturing defects.
