Aspects' Super Dome is one of the largest domes on the market.  The 18 inch diameter not only helps to prevent nature's elements from ruining your seed - it also acts as a baffle keeping some squirrels from reaching the feeder.  The dome is molded from UV stabilized polycarbonate, the strongest and most durable plastic available.  All metal hardware is included and is made of solid brass or stainless steel.
