Abstract: A sliding door assembly includes a sliding door that is slidingly mounted to a top track via one or more top guide assemblies. The sliding door is also slidingly mounted to a bottom track. Each top guide assembly includes a top guide wheel that rotationally mounts to the top guide assembly and engages the top track to guide the sliding door. The guide wheel rotates relative to the top guide assembly about an axis that extends horizontally in a direction perpendicular to a direction of travel of the sliding door. The guide wheel also movably mounts to the top guide assembly so that the guide wheel moves upwardly and downwardly relative to the top guide assembly and sliding door to correct for any variation in the gap between the top and bottom tracks.

Abstract: A modular shelf assembly has a vertical support having a channel in one face thereof and an adjustable bracket having a rear portion cooperatively configured and slidable in the channel. The bracket includes top and lower clamps each having a body portion with opposed clamping surfaces and depending leg portions. The leg portions are slidable relative to each other, and an adjusting screw is engaged with the upper clamp to effect relative movement between the clamping surfaces to clamp a shelf between the clamping surfaces. The bracket also has a positioning fastener seated in the lower clamp below the shelf and extending through the clamps to engage the support to secure the clamps to each other and to the support.

Abstract: A sliding door assembly is disclosed for use in an environment where both sides of the door are useable. The door assembly includes at least one bottom roller mechanism fitted into a lower portion of a bottom rail. The bottom roller mechanism is adjustable and concealed within the bottom rail. The door assembly further includes at least one top roller mechanism fitted into an upper portion of a top rail. The top roller mechanism is concealed in the top rail.
