Bsc Preferred DIB55-1 Bathroom Sink Drain 1-1/4 Inch

Product Description

The BSC PREFERRED DIB55-1 is a one-piece lavatory drain designed for bathroom sink installations requiring a lift-and-lock closure mechanism. The unit features a plastic body with a stainless steel rim and stopper, providing a durable and corrosion-resistant finish at the drain opening. With a 1-1/4 inch inlet and an overall length of 5 inches, this drain is sized for standard lavatory applications. The lift-and-lock design allows the user to open and close the stopper without a separate linkage assembly, simplifying the installation and reducing points of failure. Licensed plumbers and experienced DIYers install this drain as part of sink rough-in or faucet replacement projects.

The DIB55-1 is intended for use in bathroom sinks equipped with an overflow port. It fits standard lavatory drain openings and is suited for residential bathroom installations. The stainless steel rim integrates with the sink basin surface for a clean finished appearance. This drain is sold individually and is appropriate for standard sink bowl configurations where a 1-1/4 inch inlet size is specified.

Installation Notes

Installation is performed by a licensed plumber or qualified DIYer following local plumbing codes such as the IPC. Shut off the water supply and clear the P-trap before removing or replacing the drain assembly. Apply plumber's putty or the gasket provided beneath the rim before seating the drain body. Do not overtighten the drain locknut, as this can crack a porcelain or composite sink basin.
