Wera 8796 SB Zyklop 3/8" Drive Short Extension Flex-Lock Free-Turning Sleeve

The Wera 8796 SB Zyklop 3/8" Drive Short Extension with Flex-Lock is a precision-engineered socket extension bar designed for professional use with 3/8" square drive ball-lock sockets. The standout feature of this extension is the Zyklop flexible-lock system, which gives you full control over how the attached socket behaves. When the lock is activated, the socket is held securely in place, preventing accidental drops or disconnections mid-task. Deactivate it, and sockets can be swapped quickly and efficiently — ideal when working through multiple fastener sizes in sequence. The free-turning sleeve sets this extension apart for rapid fastening work. It allows the outer sleeve to spin independently whilst drive torque is applied, letting you run down screws and nuts quickly without repositioning your grip. Constructed from chrome vanadium steel with a matt chrome-plated finish, it offers solid durability and corrosion resistance suited to daily trade use. This short-length extension is well suited to working in tighter, more confined spaces where a standard or long extension would be impractical, whilst still providing the clearance needed to drive fasteners efficiently.
