The instrument case for a dental surgery comprises a drawer which slides in a housing mounted on an adjustable height stand. The drawer can be pulled open from opposite sides of the housing. The lateral outer edges of the drawer have ribs which fit into grooves in the housing. Stops at the top of the drawer at one end and at the bottom of the other end co-operate with corresponding stops inside the housing. These limit the sliding movement of the drawer so it cannot be pulled out completely. |
