Open Arm
Popular medium-size air clamp. Similar to a wide-opening vertical-handle toggle clamp, except operated by an air cylinder instead of by hand.

Choose either an open arm for adjustable spindle location, or a solid arm for fixed spindle location. 500 lbs. holding capacity. Made in USA.
This clamp is operated by a 1-1/4″-bore double-acting air cylinder, with Buna-N seals for -20 to +200F operating temperature. Two 1/8-NPT ports. 100-psi maximum input air pressure exerts 390 lbs. maximum clamping force at center of arm.
