This 1 ¼” Offset Drain with Grid (B-0898-OF) is from T & S Brass, a company with a reputation for quality and innovation. The unit is made from cast brass to hold up to the corrosive properties of water over time and finished in chrome plating for a unit that lasts long. The captive grid keeps food particles, tools, gloves and other items from entering the drain to keep them safe and keep your drain flowing freely. A 17 gauge tailpiece is made for chemicals and other hazardous materials that are commonly found in medical situations. While this drain is made to work with medical lavatory faucets, it can fit with any compatible sink model.
