This gravity-fed flow rack features a 40 series 10mm T-slot aluminum extrusion framing system. The roller rails are constructed out of our 40x40-10RP (roller profile) with snap-in rollers. Each roller rail mounts to our D28 tubular extrusion, with the height offset slightly to allow the product to roll from one end to the other. The lower end of each rail fetures a stop that prevents the product from sliding off the end. This product is fully customizable: The L x W x H can all be adjusted, as well as the quantity of rails, and various floor mount and caster options are also available.
