Bessey is known for its strong industrial and shop clamps. One of our favorites is the TSC4.516 Staircase Clamp ($59). Instead of wearing out your wrist by cranking on the handle, you can drive the tool securely using a 15/16-inch socket on a ratchet wrench. Even better, you can use a pneumatic or cordless impact wrench to crank it tight without breaking a sweat. The clamp has a throat depth of 4-1/2 inches and a capacity of 16 inches, and can apply nearly a ton of force. 800-828-1004, www.besseytools.com.
