The tool is designed to tighten steel strapping securely around a load before the strap is sealed with a metal lock (seal). Its integrated design also allows for the severing of the strap after the sealing process is complete.

Compatible with a range of steel strap dimensions. The model number "32/19" suggests it is suited for straps approximately 32 mm in width and 0.8–1.2 mm in thickness. It may also handle other widths like 19 mm and 25 mm.

Capable of generating a high tensioning force (pull force), typically greater than 6.7 KN, ensuring tight and secure bundling of heavy loads.

Built for durability and industrial use, often constructed from forged steel alloys to withstand the high forces involved during operation. The approximate weight of similar tools is around 3.2 kg.

The tool uses a manual lever-action mechanism. The process involves placing the strap end on a friction plate, positioning the strap under a feed wheel, and then swinging the tensioning handle repeatedly to achieve the desired tightness.

After the strap is sealed using a separate crimping tool (e.g., an SKS-type seal clamp), the fixed handle of the tensioner is raised to a 90-degree angle against the sealed point and swung to shear and cut the steel strap cleanly.

Designed with handles that provide leverage and may include features for operator comfort and control during the tensioning and cutting process.
