The WATCO 38610-cp is a 3/8 inch pin brass drain stopper finished in polished chrome. It is designed for heavy-duty commercial and residential drain applications where durability and security are priorities. The stopper features a replaceable Buna-N rubber seal that provides a reliable, drip-proof closure, and a theft-resistant pin design that discourages unauthorized removal. Licensed plumbers and facility maintenance technicians typically install this stopper in lavatory or basin drain assemblies requiring a pinned stopper configuration.
This stopper is suited for installations in public restrooms, hospitality facilities, and commercial washrooms where theft-resistant drain hardware is required. The polished chrome finish matches standard chrome trim packages and withstands daily use in wet environments. Its heavy-duty construction makes it appropriate for high-traffic applications where standard stoppers wear prematurely.
Designed as an OEM-style replacement or upgrade stopper for lavatory and basin drains accepting a 3/8 inch pin stopper configuration.
Installation is typically performed by a licensed plumber. Shut off water supply and clear the drain area before beginning work. Standard hand tools are sufficient for most pin stopper installations. Follow applicable IPC guidelines for drain fitting and stopper replacement.
