From the Manufacturer
Tightening the clamp and securing the edge are affected by simply twisting the handle. To clamp beading and edging strips to flat panels, a clamp is needed which prevents the material from slipping, does no harm to the clamped surfaces and provides a secure hold while, at the same time, permitting the clamped parts to be realigned if necessary. The maximum pressure applied to the edge is 450-500 lbs; the spindle travel of the pressure plate is 1-3/4 in. Panels of between 3/8 in. and 2 in. thickness can be clamped.
