These trolleys are a perfect match for 4" Stanley Box Rail. I have a board the length of a skateboard in my shop and I use it and carts mostly for pulleys and pulleys. The trolleys have attachment points and I can move the lifted item the full length of my store. I can also easily lift various objects into the attic. It said; Neither bogies nor box rails are capable of lifting tonnage, but this seems expedient on the part of the manufacturer. They're great for lifting weights up to a few hundred pounds or so, which is about as much as I've ever had to lift. I believe they could also make excellent sliding door hardware. Although I have never used them for such an application.
