Sea Sure 25mm Single and Becket 00-11

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 00-11 features a becket at one end and a clevis pin attachment at the other so this block could be used for creating a purchase system and easily attached to a fixing point with the clevis pin attachment.
