Abstract: An example adjustable angle bracket is provided. The adjustable angle bracket can include a base having a rectangular shape. The adjustable angle bracket can include a first lug having a top edge and a bottom edge, where the bottom edge of the first lug is coupled to the base, and where the first lug defines a first set of slots. The adjustable angle bracket can include a second lug having a top edge and a bottom edge, where the bottom edge of the second lug is coupled to the base, and where the second lug defines a second set of slots. The first set of slots can define a plurality of angles relative to a direction D orthogonal to the base. The second set of slots can define the plurality of angles relative to the direction D.

Abstract: A gap filler is provided. The gap filler can include a sheet having a sheet first end and a sheet second end. The gap filler can include a first frame coupled to the sheet first end. The gap filler can include a second frame coupled to the sheet second end. The sheet can be configured to be compressed between the first frame and the second frame such that the first frame extends in a direction angled away from the second frame.
