1000 Lbs Holding Capacity FEATURES: Powerful, larger-size air clamp. Similar to a vertical-handle hold-down clamp, except operated by an air cylinder instead of by hand. Toggle linkage provides high holding capacity and insures positive mechanical locking even if air pressure fails. Choose either a solid arm for fixed spindle location, or an open arm for adjustable location. Arm opens 83°. Made in USA. OPTIONAL POSITION SENSING: These clamps are optionally available with an air cylinder that has a magnetic piston ring for position sensing. Order Hall-effect or reed switches separately (see Air Accessories). MODELS AVAILABLE (STEEL):
