Introducing the 2 Way 12 in. C Clamp Locking Pliers (2-piece) Set by POWERTEC. These right-angle C clamps make it faster and easier to do projects with 90° joints by giving you the help you need to keep the parts in position while driving in the screws. They feature a dual purpose design with a clamp that converts from a pocket hole clamp to a regular C clamp with swivel jaws on both ends. When converted to a pocket hole clamp, simply slip the pin of the clamp into a pocket hole. Close the clamp and it draws the mating pieces tightly together. The swiveling clamp pad opposite the pin grabs the mating piece securely. It holds the 2-pieces firmly and the pocket screws pull the 2-pieces up tight, making a good square joint - giving you heavy-duty clamping action for a wide range of woodworking applications. Clamping Tool Commonly Used For: Drawers and cabinet making, Shelf installation, Joining boards on their edges, Carpentry, Welding, Cutting, Grinding and more. Material: Metal.
