Bemis Mfg.’s Adjustable Easy-Clean and Change toilet seat can be moved forward or backward up to 1/2” to account for varying toilet bowl sizes — both round and elongated. The hinge system allows the seat to be easily removed and replaced. The seat is anchored to the bowl by a bolt design with a finned bushing and glass-filled nylon nut (pictured). The hinge allows the ring and cover to close slowly and quietly. The seat is made of molded wood with a high-gloss finish that resists chipping and scratching.
