Bessey claims these are “America’s favorite woodworking clamp,” and indeed we have seen a number of these clamps appear on various woodworking shows. We don’t have any personal experience with them (yet), but they look pretty slick Their large, flat jaws are encased in “super-polyamid” — a plastic-like material that’s supposedly non-marring and glue resistant, yet strong enough to prove durable. A cold-drawn, profiled steel rail makes holds those jaws together, and a set-screw-based locking system locks them down.
Bessey also claims their “ergonomically-designed” (read: comfortable) wood handle lets you crank in up to 1,000 lbs. of clamping force — about double what you get with most “quick” trigger clamps. Though no bar clamp’ll ever match the speed and “handiness” factor of trigger clamps, Bessey does try to speed up the clamping process with over-sized threads. Remember, larger threads equal less turns.
K Body clamps are available in a wide variety of sizes (up to 60″ or more), and you can never have enough large clamps around the shop. Street pricing varies drastically with size, but starts around $31.
