100% Full Extension Roll-Out Shelving High density storage, E-Z Glide's 100% shelf extension allows quick, efficient loading and unloading of bulky items.  Shelves roll out even when loaded to capacity. Easy to install. Shipped knock down. The E-Z Glide has welded and bolted construction with a solid steel top deck for extra rigidity (top deck does not roll out). Top deck may be used as the pick up point to conveniently relocate empty racks and for use as additional storage. All standard E-Z Glide units have available add-on units that share a common upright. The add-on is for wall-to-wall racking of shelves...or any length in between. The add-on connects to existing shelves creating a continuous assembly of any number. Units should be anchored to the floor. (Anchors not included). FOB Shipping Point.
