A pipe clamp has a base with a fixed jaw and a beam extending from the base. A movable jaw member is slidably mounted on the beam. The movable jaw member includes a movable jaw disposed opposite the fixed jaw. A pivotable handle is mounted to the movable jaw member and a clamping mechanism is connected to the pivotable handle and operated by the pivotable handle to move the movable jaw relative to the fixed jaw. A latch secures the pivotable handle in any of a plurality of positions. A tripod stand may be provided for supporting the pipe clamp, the tripod having a multi-compartment storage spreader.

A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The stop assembly has a locking assembly that allows it to be locked to the straight edge. The straight edge clamp body can include sections that are adapted to be connected together to form the overall length of the straight edge clamp.

The present invention provides a modular vise system comprised of a fixed body, a moveable body, and a fixture plate, wherein the moveable body has a wide range of motion which enables it to grab a piece of any size that will fit within the confines of the fixture plate, the moveable body being tightened from the top of the modular vise. Tightening of the modular vise from the top allows for multiple work pieces to be placed along the moving axis of the modular vise which increases workpiece density and machine efficiency. The moveable body of the modular vise may be driven mechanically, electrically, or via a fluid driven actuator such as a pneumatic actuator or a hydraulic actuator.
