Manual tensioners for steel strapping can be brought to the work location and do not require an external power source or attachments. They are used for low-volume applications or where access to a power source is limited. The operator pushes a lever to tighten straps before a seal is applied using a sealing tool.

Pneumatic tensioners for steel strapping, also called air-powered tensioners, connect to a compressed air system to secure the ends of steel strapping in medium- to high-volume strapping applications. The operator presses a button or squeezes a lever and the tool automatically tightens the steel strapping, speeding operation and reducing fatigue. They can be used on flat or round surfaces, including bundles and pipe.

Battery-powered tensioners for steel strapping have a rechargeable battery that allows the tensioner to be easily moved around a worksite. They reduce hand fatigue that can be encountered when using manually-operated tensioners. These tensioners can be used on flat or round surfaces and do not require external attachments or power sources.
