The Atlantic Spa CP STA-TITE® is designed for universal pans and is made from durable Tecnoplast thermoplastic material. The chrome-plated hinges provide a stylish accent for your bathroom and adjust to help achieve the perfect fit for your pan. 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 you cannot over-tighten.
