Description
Classic Sea Sure designed 25mm blocks. An inexpensive range of lead blocks. Manufactured in the UK from guaranteed 316 Stainless steel. The plain bearing and tough Arnite sheave means they just keep on going. Many blocks from this range can still be found on many many Olympic class masts – because they simply work and are virtually indestructible!
The 00-13 has a becket attachment to splice or tie off to as well as a V Jammer. This block could be used to create a 2:1 purchase system for lifting that can be easily locked off on the V Jammer.
