The LARSEN SUPPLY COMPANY LAR03-4629 is a lavatory pop-up drain assembly finished in oil rubbed bronze. It provides the mechanical linkage and drain stopper needed to control water retention in a bathroom sink basin. The assembly includes the drain body, lift rod, pivot rod, clevis strap, and stopper — the complete set of components a plumber needs to finish a lavatory rough-in or replace a worn drain mechanism. The oil rubbed bronze finish coordinates with matching faucet and fixture hardware in the same family.
This drain assembly is used in residential bathroom sink installations, including vanity lavatories in new construction and remodel applications. It is suited for situations where an existing pop-up drain has failed, corroded, or where a finish upgrade is needed to match new fixtures. A plumber or experienced DIYer can complete the installation during a faucet replacement or as a standalone drain service call.
Designed as an OEM-style replacement for standard residential lavatory pop-up drain assemblies. Verify drain opening diameter on the sink before installation.
Installation is performed by a licensed plumber or qualified DIYer. Shut off the water supply and clear the P-trap before removing the existing drain assembly. Hand-tighten the drain body locknut and use pliers only to snug — overtightening can crack porcelain or composite sink basins. Adjust the clevis strap and pivot rod position to set the desired stopper travel before completing the job.
