Hi Joe!
We once carried front sections for the Junior series. When we went to reorder, they changed the pricing to be nearly as much as ordering the entire kit.
So, we instead purchase from Berea. Which turns out to be a "godsend", since other manufacturers seem to be "screwing with the thread size" (so to speak). Because of these deviations, we are planning to market the front sections as "Berea specific".
Will they actually work for "kitless"? Of course they will. But, since I don't have the expertise to advise on kitless production, I will leave that to those who do.
IF anyone is certain of the correct answer for these questions, please chime in---my best answer is "I don't know". I know they fit Berea's triton, atrax, baron and sedona. That is another GOOD reason to build your product line around Berea's offerings----they are consistent. Right now, they seem to be the ONLY ones with that characteristic.
Again, if anyone KNOWS the correct answer to the size and pitch of these threads, please feel free to give it.
Thanks,
Ed
