Steel-smith offers pneumatic toggle clamps with the advantages in the design of steel-smiths pneumatic clamps, namely, the fact that the toggle action principle with its "over centre toggle lock", provides that the clamp stays fully locked in the event of air failure, and in addition the toggle action increases the pressure exerted by the cylinder. So these clamps not only give a safer method of clamping but also much higher pressure. Another feature of these clamps is that they can be used in normally inaccessible sites where operator cannot reach. Which means all clamping positions are available within "hands reach". Steel-smith pneumatic toggle clamps are offered in hold down action, straight-line action, right angle hold down action, heavy duty and hv series.
