Zurn ZB415-3NH-7N Cast Iron Floor Drain 7in Round Bronze

Product Description

The ZURN ZB415-3NH-7N is a cast iron floor drain engineered for commercial and residential flooring applications where reliable drainage and long-term corrosion resistance are required. The body features a Dura-Coated cast iron construction with a bottom outlet configuration. It includes a combination invertible membrane clamp and adjustable collar with seepage slots, paired with a Type N D.C.C.I. light-duty strainer and a deep flanged 7-inch round grate finished in polished bronze. Licensed plumbers install this drain as part of a below-slab or surface-set drainage assembly.

This drain is suited for floor and shower drain applications in both light commercial and residential construction. The adjustable collar allows for precise finished-floor height alignment during installation. The polished bronze finish on the 7-inch round grate makes it appropriate for visible installations in bathrooms, locker rooms, utility spaces, and similar wet areas where aesthetics and function both matter.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local authority having jurisdiction. Power down or shut off water supply to the affected drainage system before beginning work. The invertible membrane clamp must be properly seated against the waterproofing membrane before securing the clamping ring. Do not overtighten the clamping ring bolts, and verify the adjustable collar is set flush with the finished floor surface before final grouting or setting material is applied.
