Machine Table Clamps for Round Workpieces

Use these clamps to hold large round parts for machining. Each clamp comes with five lengths of chain that can be combined to fit different size workpieces. Attach additional chain (not included) to hold even larger workpieces. Snap nonmarring pads into the chain to prevent damage to the workpiece. Clamps mount into t-slot nuts or fixture plates with socket head cap screws (not included).

Heavy Duty Chain Clamps for Pipe Joining and Welding

Straight

Flange

Adjustable

The open clamp design permits welding around almost the entire pipe circumference. Secure components with chains and tighten the handles.

Aluminum clamps are lighter in weight than iron clamps. Iron clamps are more durable than aluminum.

Straight clamps are for use with two lengths of straight pipe and with reducers. Flange clamp is for flanges and straight pipe. Adjustable clamp is for use with straight pipe, elbows, tees, reducers, and risers. It pivots on a hinge to hold components at any angle from 90° to 180°.

High-Leverage Chain Wrenches

An extra-long handle provides leverage for turning heavy or stuck objects. These wrenches are also known as chain tongs. When the teeth on the jaws become burred or dull, reverse them to double the service life.
