These manual devices are recommended for flexible and mobile use with packaging steel strapping. Both flat and round strapping can be carried out. Some devices work without seals, for other devices sealing sleeves are required. The MUL-16 and MUL-20 combination strapping tools have an integrated tensioning and sealing function. A small tip from our strapping experts on the use of seals: It is not the strapping strap itself that determines the type of seal, but the strapping tool used. We will be happy to advise you on the choice of the right tool and the appropriate accessories.
