As of 2016, types of snap-on window grids include Amsco's Universal Window Grille Kit and Andersen's Interior Removable Wood Grilles. Amsco's window grid is made of plastic, while Andersen's grids are made of wood. Both types of grids snap on and off for easy cleaning.
Amscos's plastic window grid is solid white and fits most average-sized windows. Customers can customize its size during assembly. Andersen's wood window grids feature a wide array of exterior colors, including sandtone, terratone and forest green. All of Anderson's grids have a natural-wood interior color. Andersen grids are available in either a prairie-style design or colonial-style design. Various sizes are available to accommodate most window types.
