A452 / A461 Pneumatic Sealer and Tensioner



The A452 pneumatic pusher type tensioner and A461 pneumatic sealer are designed to be used together for use on round or irregular shaped objects. These tools are widely used in the metals industry for strapping loads of pipe, beams, steel coils and other large and difficult to strap objects. The A452 tensioner can provide the extremely high tension required for heavy loads of metal, with a maximum tension of 1900 lbs (8500 N). The A461 sealer uses a seal with a double notch upcut seal joint for maximum safety in a one stroke operation.
