The Sea Sure "00" range offers an unparalleled range of control line configuration opportunities. Their classic design has stood the test of time.
Many blocks from this range can still be found on Olympic class masts - because they simply work and are virtually indestructable!
The high strength to weight ratio and simple construction gives years of trouble free service.
You will often find them in use after more than 30 years!
They feature hollow rivets for lightness and tough plastic sheaves that provide a good bearing surface allowing easy rotation under a range of load conditions.
The robust electro-polished 316 stainless steel construction also gives a high chafe resistance should any feed or take-off misalignment occur.
