UBI Maior ULTRA- Mastbase - tulip sheave -high load - 1,8t MWL
The RT ULTRA line originates as a custom product for TP52 yachts and was tested on the C.C.Aniene 1a Classe (the European and Italian winner of ORC 2012).
This Racing range is an evolution of the of the RT REGATA line, but its elements are lighter, smaller and can bear much higher loads thanks to textile attachments that are centralised in relation to the load.
Thanks to their special design, the blocks can also be used as a becket. The trellis geometry makes the passage of the fixing loop easier, so the head is completely released, while the lateral openings allow for loop binding.
The Torlon rollers and silver ion oxidized aluminum sheave guarantee smooth running and maximum longevity. Two holding cages for the balls on Derlin absorb lateral weight loads.
As in the RT REGATA range, in RT ULTRA blocks the two cheeks are internally interlocked so that they release the fixing screws and assure resilience and duration beyond all expectations.
