Tom, I looked into the Fernco model you
suggest.
But after speaking with an Ferno
engineer he suggested I use WC700-450 along
with part #
4.380-2.125 ( which is a bushing )
The top opening on the WC700-450 is 4
1/2 inches but the bushing will reduce
that opening
2.125" which is a much better fit for a 2 "
mast. than the 2.346" opening of the
P1056-42...
His reason for not using the P1056-42 is
when tightening the band on top , only the
immediate
area of the band (behind the band ) will
tighten to the mast leaving the area above to
bellow out.
Then if want to add caulking to this
open area with something good like silicone ,
he can't guarantee the effects of silicone
on the Ferno material.
The bushing is a very tight / snug fit
into the WC700-450 part.
