3/8" Switch Lever VDE Insulated Zyklop Ratchet & Socket Set, 17 Piece - 8100 SB VDE 1 - 

The all new Zyklop VDE ratchet is Wera's finest ratchet yet, 80 ultra-fine teeth allow for a small return angle of only 4.5°. Such a small stroke allows for fast and precise working in all situations. The extremely slim design of the Zyklop VDE ratchet makes working easy, even in confined spaces. A Ball lock mechanism ensures sockets and accessories are fitted securely, when you want to change a socket simply press on the release button and you can remove the socket efficiently. For users requiring frequent direction reversing, the ratchet features a "flick" switch which grants fast and easy change of direction. All VDE sockets and extensions offer increased safety thanks to a 2 component isolation. The yellow insulation core becomes visible in case of any damage to the outer red VDE insulation layer, to ensure safe working. The sockets and extensions also feature a ball stop groove which allows a secure fit into the Zyklop VDE ratchet.
