EXTRA HEAVY model
EXTRA HEAVY Frate Precision, is made up
in two threaded parts for a perfect coupling.
The booster of the new EXTRA HEAVY model, without O-ring
as with traditional models, adds weight without blocking the backbore.
The threads unite the two parts near the mouthpiece throat and cup,
thereby leaving the shank free to vibrate.
EXTRA HEAVY mouthpiece price complete with booster,
Euro 190.00 silverplated, Euro 220.00 gold plated.
EXTRA HEAVY mouthpiece price without booster,
Euro 160.00 silverplated, Euro 190.00 gold plated.
P.S. The EXTRA HEAVY threaded booster is only compatible
with the EXTRA HEAVY threaded mouthpiece.
