The Vevor 4-tier water jug holder is a vertical single-row rack designed to store up to four 5-gallon water bottles while saving floor space. Built from iron with a durable powder-coated finish, it is made for long-lasting everyday use in homes, offices, gyms, and storage areas. High guardrails and shelf grooves help keep bottles securely in place, while adjustable feet improve stability on uneven floors. The rack also includes an anti-tip design for added safety and is designed for easy assembly.
