Toggle Clamps

Carr Lane manufactures industry-leading Toggle Clamps designed for any application. Learn how our products work, definitions for holding capacity and clamping force and the differences between the six-basic toggle clamp action types offered by Carr Lane. It’s all below in our toggle clamps technical information section.

A toggle clamp is a quick-acting mechanical linkage where two of the elements make up a toggle action. Actuating the clamp first moves it into position, then applies clamping force by compressing or stretching the linkage elements after contacting the workpiece, then positively locks it by moving the toggle action's center pivot past the centerline of the other two pivots, against a stop.

The "holding capacity" listed for each toggle clamp refers to the maximum external force that clamp can safely resist in its locked position without incurring any permanent deformation. For hold-down clamps, holding capacity is measured with the spindle as close as possible to the handle, and will be less at the end of the clamping arm.

Open-arm hold-down clamps offer maximum flexibility and adjustability. Two flanged washers hold the spindle in place anywhere along the arm by tightening the jam nuts.
