Omni Cubed Pro-Cart AT4

Effortlessly move full stone slabs across challenging terrain, stairs, jobsite obstacles, and finished surfaces with the Pro-Cart AT4 — Omni Cubed’s premium all-terrain slab cart, redesigned for greater control, improved stability, and cleaner handling during heavy material transport.

Built as the next evolution of the Pro-Cart line, the AT4 gives installation crews a more refined, more capable cart for moving large stone and countertop materials with confidence. With a 1,200 lb load capacity and all-terrain handling, it is designed to help crews take on demanding shop-to-site moves with greater control, efficiency, and jobsite-ready performance.

Features 

• built-in folding kit
  • allows caster base rails to be folded parallel to the main support rail for easy storage in or on your A-frame.
• Quick-release clamp uprights
  • allow faster, easier adjustment for loading, unloading, and tilting stone materials.
• all-terrain tires
  • 9" flat-free, non-marking, closed-cell tires easily roll over gravel, lawns, and rough terrain. The AT4 features custom molded tires with a smooth, easy-clean surface that can be wiped down before entering finished spaces. Unlike cheap imported flat-free tires, our American-made closed-cell tires perform like pneumatic tires by absorbing bumps so the material doesn’t. And because they are “true” closed-cell, they will not absorb water or moisture.
• 1,200 lb capacity
  • supports heavy slabs, panels, and pieces while keeping the cart weight under 69lbs for easier handling and transport.
