Most popular series of push/pull toggle clamps. Plunger advances and locks by pivoting the handle forward. These clamps can also be used for pulling instead of pushing, because the handle locks back in downward position also. Choice of eight sizes, with inch or metric tapped plunger. Two of these sizes are available with our optional safety-lock feature, and one size is available with our patented self-adjusting plunger. The self-adjusting version clamps only in the "push" direction and is not tapped for a spindle.
