Abstract
An adjustable stair tray assembly includes a first angle bar, a plurality of track channels coupled to the first angle bar with each defining a cavity. A plurality of U-channels is coupled to a second angle bar, and each one of the plurality of U-channels is received in a respective cavity of each of the plurality of track channels. The second angle bar comprises a horizontal wall, a vertical wall extending from the horizontal wall, and a reinforcing flange extending downwardly from the vertical wall. A plurality of U-channels is coupled to the second angle bar, the plurality of U-channels is telescopically adjustable within the plurality of track channels to adjust a tray depth of the adjustable stair tray assembly.
