Extended Sink Flange

This Extended Sink Flange is made only for Speed Master Threaded Flange systems. It is not a universal sink flange and is not intended for standard non-threaded sink flange mounts.

The extended design is approximately 3/4" taller than a standard sink flange, giving extra reach for installations where a regular flange is too short.

Customers typically need an extended sink flange when installing into thicker sink materials or deeper mounting surfaces, such as:

• Extra-thick kitchen sinks
• Fireclay sinks
• Farmhouse sinks
• Cast iron sinks
• Granite, quartz, or composite sinks
• Any installation where the standard Speed Master threaded flange does not provide enough thread engagement

A standard flange may not extend far enough through thicker sink material for the mounting hardware to tighten properly. This extended flange provides the added length needed to help the threaded mount catch securely and tighten as intended.

Important: This part is designed specifically for Speed Master Threaded Flanges only. Please confirm that your existing setup uses the Speed Master threaded mounting style before ordering.
