Drawers for storage units such as dental cabinets are provided with a sealing system that eliminates the need for seal mounting partitions between vertically stacked drawers. Flexible seal members are attached to upper drawer handles, and these flexible sealing members contact the top of the next lower drawer handle when the drawers are closed, thus sealing the space between the drawers.

Cabinet doors are supported by a hinge system that allows the doors to swing into an open space below the cabinet as they are opened. The hinge also reduces the room that must be provided in front of the cabinet to open the door. The door is mounted on hinge bars pivotally connected to a slide that rides on runners inside the cabinet. In the closed position, the bars rest on support pegs extending from the sides of the cabinet. As the door is moved forward, the hinge bars can pivot about the support pegs and the door can swing into the open space beneath the cabinet. Pivot pegs extend from each side of the cabinet in front of and below the support pegs, and the hinge bars contact the pivot pegs as the hinge bars pivot about the support pegs. The hinge bars then pivot about the pivot pegs, which control and limit the motion of the door as it moves into the fully open position.

A dental cabinet, suitable for sit down dentistry, which is made by assemblying three cabinet sections. Each cabinet section has internal spaces which are in open communication with the internal spaces of the other cabinet sections. This allows the free passage of utility lines from one cabinet section to another and also permits easy access to the utility lines for installation and repair. The cabinet also can be assembled in place against a wall surface or as a free standing cabinet without the need for utility line excess openings in the walls or back of the cabinet.

Cabinet drawers are supported by members projecting from the sides of the drawers into slots defined by guide rails at the sides of the cabinet. Notches in the guide rails permit the drawers to pivot into an inclined position when the drawers are opened. This makes objects within the drawers more visible and accessible.
