MetroTrux™ are constructed of an advanced polymer material that is solid and durable, so they will endure tough challenges. And because they will not rust, corrode, dent, flake, chip, or peel, they will provide you with years of reliable service. Lightweight yet rugged construction is forgiving, so MetroTrux will not damage walls or doorways. Versatile construction: by positioning the two folding shelves on the CLT - either horizontally or vertically - three different truck configurations become possible. Lightweight construction and molded hand grips make steering easy. Easy washing and drainage.
