"Complete your vessel sink with this vessel pop-up drain from Novatto. It is constructed of solid brass and plated with a lifelong brushed nickel finish for trouble-free use. Chrome and oil rubbed bronze finishes also are available. Designed to work with glass, stone, ceramic or any sink with a 1.75-inch drain opening, this pop-up drain will not fit most copper bath sinks or drain openings less than 1.75 inches. The drain assembly includes two rubber seals and a brass fastener for easy installation. The drain is 8.5 inch high (when closed) with a 1.25 inch tail pipe at the bottom. Just add water and enjoy Novatto's lifetime limited warranty. Supreme packaging and boxing ensure damage-free delivery. "
