ABSTRACT:
An adjustable squeeze-off clamp for controlling the flow of a material flowing in a relatively soft-walled conduit is provided. The clamp broadly includes a static jaw, a moveable jaw with an associated adjustment member, and an over-the-center operating linkage, including an operating lever, operably connecting the jaws. The gripping surfaces of the jaws are rounded to prevent damaging the workpiece. The adjustment member is for adjusting the compressive force exerted by the jaws on a conduit prior to gripping the conduit or even prior to moving the handles. The adjustment member is operably connected to the moveable jaw, is rotated to selectively vary the space remaining between the jaws when they are fully closed, and includes a detent lock for securing it in a selected position.
