Proslat's Heavy Duty ProRack is designed to provide maximum storage without loss of floor space. The ProRack system is modular to enable your storage to grow with your needs. You can start with a 4' section and add more units or accessories as needed. Our patent-pending design delivers functional storage for bulky items on top, the flexibility to hang items below and the ability to see what's on the shelf through the grid. Built to last, our ProRack holds up to 800 lbs when properly mounted direct to studs or can be used with Proslat panels. Easy installation means there's no need to struggle with overhead mounting. Assembly required. Installation & mounting hardware included.
