Chicago STA-TITE - 5000ART The Chicago STA-TITE is an environmentally friendly, American Innova seat, designed for universal pans in Commercial and Residential applications. The adjustable pro style hinges have a large base for secure installation. This seat features STA-TITE : the patented fixing system that always stays tight and takes the guesswork out of installation. The lower portion of the nut shears off when the proper tightness is reached, so it is always perfectly tight. Environmentally Friendly: Responsibly sourced woods and water-based paints used in this seat are environmentally friendly.
