How are horizontal toggle clamps used?

Horizontal toggle clamps use an over-center locking action to hold a workpiece or fixture in the locked position.

How are toggle clamps measured?

Toggle clamps are available in multiple variants having different holding capacities. The capacity of a particular toggle clamp can be measured by calculating the distance between the clamping plate (at its highest position) & the workbench.

How does a hold down toggle clamp work?

The toggle clamp actuates against the workpiece and compresses or stretches the equipped linkages to keep the workpiece in a stationary position.

Which grease is recommended for use with Destaco clamps when rebuilding?

While dealing with the brand's mechanical clamps, we would recommend using a coupling grease like Mobil XTC. Pneumatic cylinder seals require the Magnalube G grease. They only require a few drops of lubricating oil to keep them in excellent condition.

How do you adjust a horizontal toggle clamp?

After clamping, the force can be adjusted by loosening / tightening the spindle nut (supplied with selected units for protection from abrasion, twisting or flexing).

305, 307, 309 Series Hold Down Clamps

These Destaco 305, 307 & 309 Series horizontal hold down clamps are ideal for applications where hold-down action can effectively substitute fasteners. They are compact in size and low in height for confined spaces. The horizontal clamps are equipped with a handle that can be operated either from the front or the sides. They have a flanged base with a U shaped hold down bar, a clamp bar opening angle up to 92 degrees and a holding capacity of 750 lb. Destaco 305, 307 & 309 Series horizontal hold down clamps offer a stationary alternative to removable clamps when performing repetitive tasks. These hold down toggle clamps are made of steel / stainless steel and have a horizontal handle parallel to the clamping bar. They come with a handle, a lever system, and a securing bar. The securing bar ensures that the objects won’t move and the lever system applies enough pressure on the object to keep the workpiece steady for work. These clamps feature a fixed design to secure and loosen workpieces without moving the clamp itself. Destaco horizontal hold down clamps incorporate a linkage system that applies powerful clamping force with little effort to lock or even unlock. They are equipped with a spring in the jaw to hold it in place after a few adjustments. These toggle clamps are used to hold workpieces in place using a horizontal lever handle that lays flat when the clamp is engaged. Destaco toggle clamps feature an automatic pressure adjustment system that automatically adjusts the clamp's pressure. This allows the clamping of workpieces of various sizes to adjust the pressure themselves. Selected models are equipped with the Toggle Lock Plus release lever that prevents accidental opening due to vibration.
