500,000 Cycles! Click-Out! A click indicates completed clamping. Hold-Down Style Push-Pull Style Hold-Down (Mini) Style IMAO's Snap-On System As the handle is operated, the built-in balls move following the slit to let tension accumulate on the flat spring. When the balls are positioned in the clamping pockets, the accumulated tension is released and transformed into clamping force. Pocket Hold-Down Standard Double-Lock Pocket Push-Pull Double-Lock Hold-Down Mini Single-Lock Stable! Provide the firm clamping force at every operation. Smooth! A small handle operating load generates a maximal clamping capacity. Secure! A snap-on system allows clamping a part with no errors. Highly Durable! New Sturdy Clamps! 500,000 Cycles Cleared! *) Due to one-piece body construction and heat treatment to the pressurizing members, Snap Clamps can work with little wear-out, deformation or deterioration, and do not get shaky or weak in clamping even after longterm use. Snap Clamps are far more durable than traditional toggle clamps or the like, and can be used without maintenance. *) Result of Imao original proof test (note that cycle life varies with operating conditions and environments).
