Hello I'm in the process of building my outdoor walk-in chiller......I'll be installing a 4 meter rail system that will run from an outdoor electric winch to the inside of the chiller........I'm having a hard time finding a rail that can support wheeled hooks but I found these online and was wondering if anyone has used them?........are they flimsy? Will they support a big red? Are they easy to push with a big red on them
