King Brothers Industries GDL-RFD-3500-Z Round Floor Drain Lock

Product Description

The KING BROTHERS INDUSTRIES GDL-RFD-3500-Z is a round floor drain lock designed to secure floor drain openings in commercial and industrial plumbing applications. This drain lock prevents unauthorized access, debris entry, and backflow intrusion at the drain grate level. It is typically installed by licensed plumbers or facility maintenance professionals during new construction or retrofit projects where drain security is required. The GDL-RFD-3500-Z is engineered specifically for compatibility with Zurn floor drain bodies, making it a direct-fit solution for facilities already equipped with Zurn drainage systems.

This floor drain lock is suited for use in commercial kitchens, mechanical rooms, warehouses, and other facilities where floor drains must be secured against tampering or contamination. The round profile matches standard round Zurn floor drain grate configurations. It is commonly specified in applications governed by plumbing codes that require drain protection in occupied or food-service environments.

Installation Notes

Installation is performed by a licensed plumber or qualified maintenance technician. Shut off any associated water supply and ensure the drain is clear and dry before installing the lock. Follow all applicable local plumbing codes and manufacturer guidelines during installation. Do not force-fit the lock onto a drain body it was not designed for, as this may damage the drain or the lock mechanism.
