The Pro-Cart AT4 is designed to overcome the challenges of moving heavy stone over curbs, stairs, gravel, lawns, and other rough terrain. Built as a premium upgrade in the Pro-Cart line, this all-terrain cart helps crews transport large, cumbersome slabs, panels, and countertop pieces while reducing the physical burden on workers.

The AT4 features a 4.5" clamp opening for thicker materials, mitered pieces, and larger edge details, along with an upgraded quick-release clamping mechanism that allows for faster, easier adjustment without removing the clamp from the cart. It also includes 9" tires, EPDM rail padding, silicone end caps, and an adjustable wheelbase designed to improve control and stability across challenging jobsite conditions. The included Folding Kit allows the caster rails to rotate beneath the support beam for easier storage and transport.

Next Level Super Duty All-Terrain Cart

Collapsible Clamp Uprights

for easy removal and tilting of stone

Protective end caps & Radiused Corners

Slight bumps from a sharp edge or corner can damage materials (especially glass), and small chips can become huge cracks over time. Protective end caps and radiused corners on all extrusions help protect the material from these damages.

Grey Non-marking Rubber

Grey-non marking rubber for the material to rest on.

High Clearance

16" height from support rail to ground to easily clear and rest on stair treads

Lower Deck Height

At 16 inches from the ground to the deck, it still has 64 inches of clearance in a standard door frame

built-in folding kit

allows caster base rails to be folded parallel to the main support rail, down to 56-1/2" x 12" x 16" for easy storage in or on your A-frame.

all-terrain tires

9" flat-free, non-marking, closed-cell tires easily roll over gravel and lawns. Unlike imported flat-free tires, our American made closed-cell tires perform like pneumatic tires (absorbing bumps) so the material doesn’t. And because they are “true” closed-cell, they won't absorb water or moisture like cheap imported tires.

Quick Release Speed Clamp

Adjust the clamp for quick macro and micro adjustments, allowing for faster and easier adjustment. Fits up to 4.5" (114.3 mm) edges and holds the material securely.

Adjustable wheelbase

offers adjustability, allowing the operator to match the cart wheelbase to stair rise and run. This helps crews move large, heavy pieces up stairs with greater control while reducing the risk of damage to the material or cart.
