CHANNELLOCK adjustable wrenches feature non-protruding jaws for greater access in tight spaces. 

• Precise four-thread knurl for improved adjustment accuracy
• Measurement scales are laser-engraved for sizing nuts, pipe, and tube diameters
• Optimal head width and non-protruding jaws allow accessibility for hard-to-reach applications
• Rugged chrome vanadium steel construction
• Chrome finish for ultimate rust prevention

Wera Joker VDE-insulated self-setting/self-adjusting ratcheting adjustable wrenches ensure the right fit by automatically adjusting to metric and imperial hex head nuts and bolts.

• Insulated handles are individually tested for safe use at up to 1,000 Volts
• Self-adjusting feature provides automatic and continuous grip of hexagon screws, bolts, and nuts
• Integrated lever mechanism securely clamps the hexagon screw or bolt between the jaws, reducing the risk of slippage or damage
• Return angle of only 30° at the open end to avoid time-consuming flipping of the wrench during fastening jobs
• Ratchet mechanism for continuous driving and comfort in very confined working spaces
• Handle design provides comfort and increases safety with the anti-slip protection at the front end of the handle

Wera Joker standard uninsulated versions with same features (except insulated benefits) are also available.
