A drawer system for the storage of plate material, tools and other products. The drawers can be easily opened (100%) and close manually. The unit is of robust welded and bolted construction, capable of dismantling and on which the load bearing guide rails, which are vertically adjustable in 47mm increments, are mounted. The unit can be supplied with folding side frames on one or both sides and which can be locked for security purposes. The drawers are fitted with permanently lubricated “sealed-for-life” INA roller bearings with an extra-thick external ring. The drawers are normally of open construction but they can also be decked with steel or wood. The system can also be provided with a static upper mezzanine.
