I used to work for Amazon Fulfillment Center BFI4 in Kent WA and we had these tools on the dock. These tools are instrumental to the success of a dock. I worked with this shrink wrap pole day in and day out, in a sense I trained myself on how best to operate it to make the products and pallets most secure as possible. Needless to say once I found a different profession as a semi truck driver I had to buy one for my own keeping to use as I needed wherever I needed. This tool will save your back, literally, it makes shrink wrapping pallets from floor to the top of double stacked pallets a breeze, while maximizing the use of the shrink wrap most efficiently. Shrink wrap roles last longer and can be applied to a pallet tighter to ensure the safe transit its contents.
