The Pro Series top tool box collection includes a 53" 8-drawer tool chest and a garage top built for the 72" 14-drawer rolling tool box, both made from 18-gauge spot-welded steel. They sit on top of a matching Pro Series rolling tool box to add storage and work space in a home garage or professional shop. The 53" chest has full-extension drawers on 100 lb. ball-bearing slides, and the 72" garage top adds a stainless steel work surface, a built-in power strip and a gas-strut lid.
