Definitely the strongest quick-acting screw clamp available. The patented grooved-bar design works smoothly and positively – just slide the bar forward to contact the workpiece, then turn clockwise to apply force. To unclamp, turn counterclockwise and slide the bar back. As strong as a standard screw clamp, but much faster. Four-prong knob provides a firm grip for applications requiring quick tightening and high torque. Available in 3/8", 1/2", and 5/8" bar sizes, each in a choice of several lengths. Made in the USA.
Turning the clamping bar clockwise engages internal grooves in the threaded collar. Both components then turn together as a single unit to apply screw force.
Turning the clamping bar counterclockwise loosens the screw clamp and disengages the collar, allowing the bar to slide back and forth.
1. Slide clamping bar forward to contact the workpiece.
2. Turn clockwise to engage the threaded collar and apply clamping force.
3. After machining, turn counterclockwise to unclamp and disengage the collar.
4. Slide clamping bar back for unloading.
Choice of four-foot types. Bar-Lok Quick-Acting Screw Clamps use our patented left-hand-thread swivel-foot system. The ball end of the body screws into the foot for easy installation and removal. Once the ball threads pass beyond the foot threads, the foot can rotate and pivot freely (20° total angle). Foot threads are left-hand to positively prevent accidental backout during use. Delrin® feet are optional for types A and B. To order with a Delrin® foot, add "N" to the part number, e.g. CL-14-BLTBN. Note: Delrin® feet are not threaded – they snap on and off.
