Manual Clamping Technology Selecting The Proper DE-STA-CO Clamp
The information contained in this catalog is designed to help you select the right damp to accomplish your job. DE-STA-CO distributor personnel, as well as DE-STA-CO's Technical Service department, are qualified and willing to offer assistance in special or unusual applcations. For most ordinaryapplications, however, consideration of the following points will lead to the proper clamp selection • Size and shape of the parts to be held. • Uniformity of part size (Should you consider a springloaded spindle to compensate for uneven parts?) • Holding capacity required • Strength and dexterity of the operator • Operator's position (Should you use horizontal or vertical handle models?) • Frequency ofoperation (Should you plan for a temporary or permanent fixture?) • Time cycle of operation (Should you consider a turntable or conveyor set-up if curing time is required?) • Cycling time and sequence (Should you consider air-operated models that can be operated faster and in sequence?) • Environment (Should you consider stainless steel, aluminum or lightweight composite models?) (A) the partmaterial: such as, steel, wood, plastic or glass, etc. (B) the surface finish of the part: such as, polished, hard or soft, etc. (C) the machining or assembly operation: such as, milling, welding, drilling, bonding, joining or sealing a mold, etc. In order to ensure clamp strength is not compromised, use all the mounting holes provided. Red handle grips are provided on each model. Users should onlylocate their hand in this area when operating ttie clamp, thus reducing the possibility of injury. Safety Handle This ergonomic handle provides greater operator comfort.

Safety Feature This safety link prevents accidental injury to an operator when opening the damp. Clamp Series 201, 202, 207, 210,247,267 Safety Distance Exdusrve handle design gives more hand clearance between bar and handle whenclamp is in fully open position. Cramp Series 213, 217, 227, 237, 245

Processing Applications
Remember, the same toggle action force multiplying principle can be applied to other tasks besides holding. Certain DE-STA-CO models can be used to position parts, power fixtures or perform mechanical functions such as piercing sheet metal, staking rivets or locating.

OEM Applications
DE-STA-COdamps provide ready-made, compact devices for moving or holding components. A little imagination will often show the product designer a way to obtain motion or locking force 'with no tooling costs and often at less cost than custom designed components. Thousands of DE-STA-CO clamps will be found installed as original equipment for cleanout door latches, wheel locks, positioning devices, etc.Safety
Our concern is not only the constant high quality of our products, but also their fail-safe and foolproof handling. The knowledge gathered since 1936 guarantees a developed, safe and high-quality clamping unit. A certain damping force 'will be necessary to safety hold a part.This force is determined by taking the following into account: www.destaco.com

How to find the most suitable clamp? The following criteria will narrow the selection of the clamp type:
• • • • The type of fixture The required holding capacities Thesize conditions in and around the fixture Action required by clamp to perform required task

The most important models at a glance: Vertical hold-down clamp
• Handle is vertical in damped positjon • Holding capacities up to 22,25kN[5000lbf.] • Opening angle between 65° and 215°

Straight line action clamp
• Forward movement of the handle pushes the plunger into the forward...
