This is a single Decolav 9030-PB polished brass umbrella drain. An umbrella drain is permanently open and is used for installations such as vessel sinks that do not have an overflow drain. The last photo shows this installed in a vessel sink. The top measures just under 3" in diameter with a built-in collar to raise your vessel sink 3/4" off of the counter it is mounted on. This was originally designed for mounting vessels on 12mm thick glass countertops, but it can be used on non-glass counters up to 3/4" with the removal of the rubber washer. Fits standard vessel sink openings (1-3/4" to 1-7/8"); the exact outer diameter at the threads is 1-5/8", but you will want some clearance around it. Includes gaskets and washers shown in photo - sink shown is not included. Decolav is known for its design innovation and theļæ½high quality of workmanship in its products. You can find Decolav products online, in high-end design shops, and in mass retailers such as Home Depot. Be wary of the manufacturers that you have never heard of peddling low cost knockoff designs - the quality does not compare.
