 SWING CLAMP ASSEMBLIES

FEATURES: Long-reach swing clamp that can be hand tightened for medium clamping force. This post-mounted version is ideal for tight spaces, with a long mounting post for increased strength. Install in a reamed hole. Choice of knob handle or sliding ball handle.

SIZES: Available in five sizes, with USA or metric mounting post:
• 1-1/2" Reach
• 2" Reach
• 2-1/2" Reach
• 3" Reach
• 4" Reach

SWIVEL FOOT: Swing Clamp Assemblies 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 back out during use. Delrin® feet are optional. To order with a Delrin® foot, add "N" to the part number, e.g. CL-1-SWA-1N. Note: Delrin® feet are not threaded – they snap on and off. For other foot types, see Feet for Swivel Screws (order separately).

MATERIAL: Swing arm > Nodular iron per ASTM A536 grade 65-45-12, zinc plated clear chromate. Post and mounting screw > Mild steel, black oxide finish. Other components > See catalog information for each specific item.

 UP-THRUST CLAMPS

FEATURES: Combination clamp and locator with a unique upward clamping action. Up-Thrust Clamps locate off of the part's top surface and clamp up from below. Pushing down on the cam handle pulls the lower jaw upward. This clamps the workpiece against the stationary upper jaw, whose bottom surface is ground for precise location.

SIZES: Available in one size, with 1/2-13 mounting thread.

ADJUSTMENT: The lower jaw has two clamping surfaces 180° apart, one for thinner parts, the other for thicker parts. After selecting the appropriate clamping surface, move the lower jaw up or down into final position by rotating the cam handle.

MATERIAL: Steel, wear surfaces hardened, black oxide finish.
