Bessey GearKlamps

Crank handle surrounds the steel bar, saving the skin on your knuckles when clamping in tight spaces.

92% of 100

Bessey's GearKlamp boasts all the features and affordability of other F-style clamps, but with a unique twist that sets it apart from the crowd. In order to allow clamping where space is limited, the crank handle has been moved from the acme screw to the clamp bar itself. A patented gear train then transfers clamping power back to the screw. The result is an F-clamp with greatly improved finger clearance and comfort in tight spaces. Use them to clamp items to workbenches and shop tables with a narrow overhang, or to reach into narrow openings without having to squeeze your hand through as well. To close the clamp, simply slide the handle up the bar—the internal clutch prevents it from sliding back down. To open, just release the clutch with the trigger.


  • Saves the skin on your knuckles when clamping in confined spaces
  • Fast closing action—just slide the handle up the bar; no need to release the clutch
  • To slide the clamp open for clamping large objects, just press the quick-release button
  • Powerful clamping force of up to 450 lbs
  • Fully enclosed gearbox keeps out dust and debris
  • Tempered steel rail and fiberglass reinforced polyamide housing for durability
  • No-mar pad on fixed end can be removed to reveal a grooved section for clamping round objects
  • Swiveling pad on movable end self-aligns with angled objects

how "deep" ar the jaws?
tom p on Apr 15, 2019
BEST ANSWER: the technical specs list the throat depth as 2 3/8 inches
Where are these clamps made?
Mike Regimenti R on May 4, 2020
BEST ANSWER: The bar and threaded parts are steel with some sort of hard plastic for the body. Keep in mind this is a speciality clamp you wouldn't use every day, so while it is lightly built it should hold up for it's intended use. I use Bessey clamps every day in my shop along side Wetzler's and they hold up fine.
How wide do the jaws open on the 12" GK30 to hold stock between clamps?
Patrick on Aug 14, 2019
BEST ANSWER: I just measured 12-3/16” with everything open as far as possible.
