Abstract: A feeder apparatus comprises a plurality of walls defining a feeder body, mounting structure, and a feed holder. The feeder body is hingedly, optionally hingedly and/or removably, mounted to the mounting structure. In some embodiments, the feeder apparatus further includes a blocking plate which is hingedly, optionally hingedly and removably, mounted to the mounting structure. One or more of the feeder body walls and the feed holder have cooperating sliding structures, enabling the feed holder to be slidingly received into, and/or removed from the remainder of the feeder apparatus.

Abstract: A slidable panel assembly has a multi-component perimeter frame. The perimeter frame houses a sheet-type or panel-type structure therein. Each of the outwardly facing edge surfaces of the perimeter frame has a channel extending thereinto. The leading and trailing portions of the perimeter edge channels, adjacent the perimeter corners, define a step change in channel depth with respect to the remainder of the edge channel.

Abstract: A draw-wedge fastener assembly has a draw plug, an anchor body, and a bolt which slidingly and rotatably extends through the anchor body, and threadedly extends through and engages the draw plug. The draw plug has first and second expandable terminal ends. The anchor body has a first, generally flat, end surface at a first end, and a generally tapered second end. One of the expandable ends of the draw plug interfaces with and expands over the tapered end of the anchor body. The other one of the expandable ends of the draw plug expands as the bolt passes therethrough.

Abstract: A feeder apparatus comprises a plurality of walls, mounting structure and a feed holder. The plurality of walls communicates with the mounting structure to accommodate mounting the feeder apparatus on the outside of an animal confinement structure, e.g. a cage. One or more walls of the feeder body and the feed holder have cooperating sliding structures, enabling the feed holder to be slidingly received into, and/or removed from the remainder of the feeder apparatus.
