If things are loaded by "floors", you will need slings (belts) so that they do not fall apart. It would be nice if the kit included a fabric "sleeve" to the height of the control knob: you put on a sleeve on a trolley loaded with floors; then nothing will fall apart. The width of the sleeve should be regulated by straps with fasteners (three pieces). Sleeve height-control handle height. But you can do with slings.
