Toggle Clamps

CL-400-PTC
Open Arm

Super-compact air clamp for applications where space is at a premium. Similar to a wide-opening vertical-handle toggle clamp, except operated by an air cylinder instead of by hand. Toggle linkage provides high holding capacity and ensures positive mechanical locking even if air pressure fails. Clamping arm opens 100°. The slotted open arm provides adjustable spindle location. 100 lbs holding capacity. Made in the USA.

This clamp is operated by a 3/4"-bore double-acting air cylinder, with Buna-N seals for -20° to +200°F operating temperature. Two #10-32 ports. 100-psi maximum input air pressure exerts 100 lbs maximum clamping force at the center of the arm.
