No. The two choices you have for rubber manufacturers to use in a Sorbo channel are Sorbo (the rubber u have and do not like) or Black Diamond - Flat Top.
Basically Sorbo made their rubber a
different shape (profile) so that u would have to use their rubber with their channels.
All the other channel manufactures (Ettore, Unger, Pulex) use a round top profile rubber that can be used with other squeegee brands.
Black Diamond (Rubber Company)
Is providing a bridge so u can choose to use their rubber instead of Sorbo.
It is cheaper than Ettore/Sorbo and supposed to be fairly good as I said I am waiting for some to arrive and will post a honest critical review ASAP.
