The MetroMax-i Open Grid 4-Shelf Polymer Lab Cart is acclaimed as one of the world’s most robust, versatile, and corrosion-proof shelving systems. This all-polymer shelving is designed for superior durability and is constructed from advanced polymers with Type 304 stainless steel corners. The shelves are adjustable in 1-inch increments and feature removable, easy-to-clean open grid mats that enhance air circulation and light penetration.

A lifetime warranty backs this cart against rust and corrosion and includes built-in Microban antimicrobial product protection, ensuring it remains cleaner between cleanings. A rigid four-sided shelf frame and robust stainless steel corners with complete 360° capture of the wedge and post provide unparalleled stability, strength, and structural integrity. Depending on the choice of casters, each cart can safely store or transport between 600 and 900 pounds.

The cart is equipped with two 5" polyurethane swivel casters and two 5" polyurethane swivel casters with brakes, featuring chrome-plated horn stems, axles, and optional brakes suited for dry environments and medium-duty applications. The non-marking polyurethane flat tread and polyethylene hub, along with ball bearing swivels and axles, ensure smooth mobility. The casters are NSF listed, and bumpers are included to protect against impacts. The brake style is a side brake for secure parking.
