Eagle Group MMBB/A-4 is a heavy-duty shelving upright designed for robust storage solutions. Standing at 48 inches tall, this floor-to-ceiling mount is ideal for use with cantilevered shelving systems. The double-faced unitized uprights are engineered to attach securely to both the floor and ceiling, providing stability for center room storage. Constructed from durable aluminum, these uprights can be bolted or welded back-to-back for enhanced strength and support. Please note that they must be used in conjunction with floor and ceiling brackets for optimal performance.
