When using a complete bundle, attention should be paid to the variation of the bundle webbing in addition to the fastening position of the two ends. Fastening devices are strictly required in the instructions for use and only undamaged tensioners are used. The manufacturer of the binding device refers in particular to the synthetic flat webbing, i.e. the tensioning webbing. When fixing the binding device, the metal handle is shaken up and down to achieve the effect of tightening the webbing and to achieve the function of fixing the goods. As a result, the webbing will not suffer little damage during the entire binding process and inconspicuous cuts will result in unsuccessful binding. Sharp edges and corners of the binding are not allowed to touch the webbing of the binder directly. Just because the webbing may be fine when the side tensioner bindings are pulled together does not mean it is fine during shipping. Severe shaking during transport can cause the edges of the load to wear on the tensioner. In severe cases, it will be separated or even cut off. Use the cargo tensioner safely and start understanding.
