Struggling with messy under-mount sink drain installations? Our Top-Mount Sink Drain Flange turns plumbing hassles into simple fixes—designed explicitly for 3.5-inch sink openings. Unlike traditional under-mount systems that require drilling or fixture adjustments, this flange sits neatly atop your sink deck, making installation quick and stress-free for both DIYers and pros.
At its core lies a robust 4.5-inch brass flange—corrosion-resistant and built to last—providing a solid base for secure connections. Pair it with our included brass strainer and basket: this dual-layer system traps hair, soap scum, and debris before they clog pipes, keeping drains clear and reducing clog-related repairs.
For reliable performance, the flange features 1-1/2″ x 11-1/2″ NPSM threads that fit most standard sink fixtures—no custom threading needed. The polypropylene drain housing adds durability without added weight; it withstands impact (so no cracking) and resists harsh cleaning chemicals (safely handle bleach or abrasive sponges).
We’ve simplified things further with manufacturer-supplied installation guides and a full specification sheet (right here on the page)—so you’ll have all the info you need without extra searches. Whether you’re replacing an old drain or installing a new one, this flange delivers leak-proof performance, durability you can trust, and the convenience of pre-packaged components. Upgrade your sink setup with a solution that saves time, prevents headaches, and keeps water flowing smoothly.
