The wera 8794 a zyklop wobble extension is a 1 4 drive extension bar designed to provide access to fasteners in tight, awkward, or obscured installation spaces. Its 15 swivel angle in all directions allows the socket to work at an offset, making it ideal for use where a straight extension simply won't reach or align. Built for use with wera's zyklop ratchet system, this wobble extension is compatible with 1 4 square drive sockets fitted with a ball lock. The ball stop groove keeps sockets securely in place during use, reducing the risk of dropped components in confined working areas. The knurled lower end provides a positive grip for manual applications, making it practical when torque needs to be applied by hand rather than with a ratchet. Manufactured from chrome vanadium steel with a matt chrome-plated finish, it offers strong resistance to corrosion and everyday workshop wear.
