Next Level Heavy-Duty All-Terrain Cart

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.

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.

High clearance

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


Lower Deck Height

At 15" from the ground to the deck, it still has 65 inches of clearance in a standard door frame

1,200 lb capacity

weighs only 64 lb

Clamp opening

Opens up to 3" (76.2 mm) and holds the material securely
