Blanco 240334 – Frequently Asked Questions
1) Will the Blanco 240334 disposal flange fit a standard 3-1/2 inch sink drain opening?
Yes. The Blanco 240334 waste flange is made for standard 3.5 inch drain openings, which is the normal opening on a kitchen sink cut for a garbage disposal. If your sink bowl is drilled for a basket strainer rather than a disposal, measure the opening first, since the flange only suits the 3.5 inch disposal size.
2) Does the Blanco 240334 flange work with an InSinkErator garbage disposal?
It's designed to work with most InSinkErator garbage disposals, mounting into the standard 3.5 inch drain opening the disposal mount sits in. It's the visible flange ring at the sink deck, not the disposal mounting assembly itself.
3) What color is the Blanco 240334 and what sinks does it match?
The 240334 is the Cinder finish. Blanco color-coordinates these flanges to match the full SILGRANIT sink range, so a Cinder sink gets a flange in the same color instead of a contrasting chrome ring. If your sink is a different SILGRANIT color, order the matching color-coded flange rather than this one.
4) I'm replacing a worn chrome disposal ring on a Blanco SILGRANIT sink. Is the 240334 the right part?
If the sink is Cinder, yes. The 240334 is the Cinder color-matched metal flange for a 3.5 inch disposal opening, so it swaps in for the stock metal ring and gives a color-matched look instead of chrome. Part number to quote is Blanco 240334.
5) Is the Blanco 240334 metal or plastic?
It's a metal disposal flange, finished in Cinder to match the sink color. That matters for a rental or commercial kitchen where a plastic ring gets chipped or stained at the disposal opening.
6) Does this Blanco flange let water drain through, or does it seal the opening completely?
Both, depending on how you set it. The flange seats to create a tight seal that keeps food and debris out of the pipes, and it can also be positioned to let water drain through, which is what you want during food prep at the sink.
7) Does the Blanco 240334 include the disposal mounting hardware or a stopper?
It's the disposal flange itself. Plan on using the mount assembly that comes with your garbage disposal, and order a separate strainer or stopper if you need one for the other bowl.
