The RIDGID Quick-Acting Pipe Welding Clamp is designed for quick setup and easy alignment of pipe from 2 to 12 inches. It comes in two sizes — 2- to 6-inch and 4 1/2- to 12-inch — allowing contractors to select the clamp best suited to their needs. Both sizes offer quick-release buttons and integrated handles for fast adjustment, alignment and easy switching between pipe sizes. They also include spring-loaded winged setscrews for precision three-point alignment and an integrated size gauge for simple pipe measurement. ACME threaded screws transmit ample clamp force, while the heavy-duty steel construction is built to withstand rugged job site applications. 800-769-7743; www.ridgid.com.
