T186-Standard toolroom clamping,
light and medium-duty welding, sheet metal work, etc. T321-Identical to T186 except with deeper throat. T285-Deep throat medium-duty-for special uses and awkward
positions or areas.
T290-Medium for normal machine shop
work. T257-Heavy-duty for extreme clamping forces or length. High
tensile, heat-treated steel frame.
OPERATION
Operation is very simple.
The operator slides the spring loaded moveable jaw toward the workpiece
to the nearest notch where it locks into the detent. Hand tightening the
screw advances the clamp jaw. The jaw advances the tilting rotating to
twist the work or the clamp out of position. An unusual and very useful
feature of these clamps is the ability to use the clamp for spreading or
locating as well as squeezing.
