Install undermount sinks quickly and securely with a fully adjustable support system that eliminates wood blocking, shims, and custom brackets.

Looking for a Faster, Stronger Undermount Sink Support System?

The Vance Industries Sink Undermounter is a professional undermount sink bracket system designed to simplify sink installation while providing long-lasting support for granite, quartz, marble, engineered stone, and solid surface countertops. Installation typically takes just minutes, eliminating the need for wood blocking, shimming, or custom-built support frames inside the cabinet.

Designed to fit 25", 36", and 50" cabinets, each bracket can be trimmed to fit virtually any cabinet width. The fully adjustable design accommodates different sink depths and countertop thicknesses while allowing installation either side-to-side or front-to-back depending on cabinet configuration.

The Sink Undermounter also meets Caesarstone® requirements for undermount sink installation and can even be used to install round and oval sinks by using two bracket sets.

How It Works

Each bracket mounts securely inside the cabinet using standard screws. The adjustable support arms accommodate different sink sizes and countertop thicknesses, while the included leveling bolts allow precise height adjustment so the sink rim fits tightly against the underside of the countertop. For round and oval sinks, two Sink Undermounter sets can be installed perpendicular to one another for complete support.

Why Choose Sink Undermounters?

Traditional undermount sink installations often require time-consuming wood blocking, shims, or custom-built support systems that add labor and can shift over time. Sink Undermounters eliminate these extra steps by providing a fully adjustable mechanical support system that installs quickly and delivers dependable long-term performance.

The trim-to-fit design offers outstanding flexibility across multiple cabinet sizes, while the included leveling bolts allow installers to achieve precise sink alignment with minimal effort. Its compatibility with virtually every major countertop material also makes it an excellent solution for fabrication shops, installers, and remodeling contractors.

Whether you're installing a stainless steel, composite, porcelain, or cast iron undermount sink, Sink Undermounters provide the strength, adjustability, and simplicity professionals rely on.
