The Pro-Cart AT1 provides a solution to the challenges associated with large and cumbersome countertop installation carts. The cart is constructed from aluminum tubing, so it is strong and lightweight at less than 50 pounds. Important for climbing stairs, the cart stays attached to the countertop when lifted and the 8 casters allow resting on stair treads. Pneumatic casters dampen vibrations and enable travel across rough terrain such as gravel or lawns.
