Csb International Products 521SNBN Waste Arm 1-1/2 in Brass

Product Description

The CSB INTERNATIONAL PRODUCTS 521SNBN is a 1-1/2 inch nominal waste arm constructed from 20-gauge brass with a polished chrome finish. A waste arm connects a sink drain to the drain trap or branch drain, carrying wastewater away from the fixture. This fitting is a standard component in residential and light commercial sink drain assemblies. Licensed plumbers and experienced DIYers install this part during new construction, remodel work, or drain system repairs. The polished chrome finish suits exposed drain installations where appearance matters.

This waste arm is suited for residential and light commercial sink drain applications where a 1-1/2 inch nominal fitting is required. It is a common choice for kitchen and bathroom sink installations where the drain piping is visible under the sink and a finished look is desired. The brass construction provides durability in wet plumbing environments.

Key Features

• 1-1/2 inch nominal size fits standard residential sink drain configurations

Installation Notes

Installation is typically performed by a licensed plumber or qualified tradesperson following local plumbing code requirements. Shut off the water supply and confirm the drain is clear before beginning work. Hand-tighten slip-joint fittings first, then snug with slip-joint pliers — do not overtighten brass fittings, as this can crack slip nuts or deform sealing surfaces. Inspect the assembly for leaks after restoring water service.
