InSinkErator Extended Sink Flange

Got the insinkerator kit for a customer but the flange didn’t fit in the Belfast sink so had to get the longer one. Worked fantastic

To fit Insinkerator to Belfast sink you will need this flange extension. Delivered quickly and worked as described.

The part arrived well packed and early to the advertised date. It is of the same quality as the standard part that comes with the unit originally. It does seem expensive for what it is but if you must have this extended version to suit your sink you have no choice.

Necessary for a ceramic sink, excessive price

Fast delivery. Great product. This flange works very well when you use a Belfast sink. The only think you have to bear in mind is that you don't normal have the ability to use the overflow of the sink when you use the insinkerator, but my builder made a hole in the flange which makes the overflow useable again.

Perfect for ceramic sink. Replaces shallow flange, did the job perfectly

Serves its purpose but disgusting price after you’ve just spent £££ on a waste disposal. Should come as standard.

Expensive product but good quality. Needed for Belfast sinks etc. Would be nice to have the choice to have this size rather than the standard size that comes with your new insinkerator when ordering.

La mia cucina ha un piano lavoro in ecotek e lo spessore per la piletta è di 2 cm. L’originale non ci stava perché poco profondo, invece con questo ho speso due minuti ed ho installato tutto. Fantastico se consideriamo che avrei dovuto limare lo spessore e non sarebbe venuto bene sicuramente… un po’ caro a mio avviso. Forse vi stava se includevano anche le guarnizioni e tutto il resto per installare. Ma ora sono a posto!

Con questo articolo ho risolto il mio problema

La misura e' compatibile con alcuni tritarifiuti cinesi di prezzo moderato. Io l'ho comprato per poter installare un tritarifiuti che ho pagato 85 euro qui su Amazon. A 35-55 Euro ( a seconda del venditore, credo) questo adattatore e' un furto, oltretutto la qualita' e' inferiore alla flangia di serie del tritarifiuti che ho acquistato. Comunque fa' il suo lavoro e mi ha evitato di acquistare un tritarifiuti di costo triplo. Quindi 3 stelle anziche' una !

If you are trying to install an Insinkerator disposal unit (or even another brand) and have a Farmhouse sink you’ll need this Deep Sink Flange. The standard flange is 1-1/2 inches deep and it does not leave enough room for the thickness of a farmhouse sink. Here is the rest of the story... I go to my daughter's house to install a new dishwasher and end up installing a new disposal unit as well. She has a farmhouse sink and the plumber (or the person impersonating a plumber) installed the disposal on a 1” thick farmhouse sink with the standard flange. He did not use the backup flange and just had the screws directly contacting her expensive sink so the whole disposal unit was putting pressure on three screws. It was leaking badly, stinking badly and damaged the cabinet. [see graphic with screw indents in the sink] If your sink is thicker than ¾ of an inch you need this Deep Sink Flange but if your sink is between ¾” and 1” insinkerator does not have the full solution. There are two screw lengths they provide with the standard flange that comes with the new disposal unit which are the H1 which is 1-1/2 inches and H2 which is 1-1/8 inches. Now if you install a 1” sink in the Deep Sink Flange which is 3-1/2 inches deep that means you have about 2-1/2 more inches of flange. Of course, there is the snap ring which does take up some depth but the problem is that Insinkerator does not have screws long enough for a 1” sink and definitely not a ¾ inch sink. My solution was to add a second [see graphic] backup flange (kind of a kludge) and if it does NOT hold, I will obtain some longer stainless-steel screws. They should be called Insinkerator H3 screws and would be a 5/16-18 [18 threads per inch] and 1-3/4 inches long and the end should be flat so as to have better pressure on the back flange. Last comment – yes at $50 this deep flange is a rip-off and if it came with the 1-3/4 screws it would still be a rip-off but at least you could install your disposal unit.
