Don’t worry, we have according solutions for your situation.
Considering the tall packing boxes, for example the refrigerator box with a small base area, but a relatively high height. It is liable to topple and fall in vibration test if fastened by our regular guard rails.
In order to prevent this from happening, we will extend the guard rails to a higher position to match the height of your package and configure with 4 more clamps (8 clamps in total with 2 layers) to hold the carton firmly.
In a word, the height of guard rails can be tailored on the basis of your package height.
