No more having to adjust your toggle clamp manually when your stock changes thickness even slightly. Bessey's Auto-Adjust Toggle Clamps will revolutionize the way you use toggle clamps, they automatically adjust to different workpeice thicknesses while maintaining constant clamp pressure. The removable non-Marring plastic cap is included on the 7/8" diameter pads. A simple screw at the base of the operation handle allows you to dial in the amount of clamping pressure to be applied. A locking nut on the screw prevents it from changing during use. The integrated clamping force adjustment screw can be used to create an applied clamping force from 25 to 550 lbs. (max holding capacity 700 lbs.) One Bessey Auto-Adjust Toggle Clamp can replace a range of competitive toggle clamps. The large (2-1/4" x 2-1/2") heavy steel flanged base is designed for use with 1/4" or M6 fasteners. Mounting holes are sized & spaced for easy mounting and versatility. The large nicely shaped 1" x 2-1/8" handle offers greater user comfort and ease of operation.
