Product Description

Professional-grade 3/8-inch drive extension bars with unique socket lock mechanism. Slide spring-loaded collar back, attach socket - stays on until you take it off! Works with any 3/8-inch drive socket, shallow or deep, thin- or thick-wall. Heavy-duty hardened Chrome-Vanadium steel for extra strength; mirror-chrome anti-corrosion finish. Set of the 3 most commonly-used extension bar sizes: 3", 6" and 10". When difficult access requires you to use socket extension bars, you don't need more aggravation from sockets dropping off the extension into hard-to-reach dark holes. This premium-quality set of extensions solves that problem with a simple but highly-effective locking mechanism that won't let go of the socket - and doesn't hinder access or versatility. An essential new adaptation for every professional and serious do-it-yourself mechanic.
