Low-friction bullet blocks lead control lines aft. They are compact and lightweight, with fast trim and release under high or low loads. A range of styles lets these blocks adapt to almost all control line applications.
This block was used in the past for the through-deck spinnaker pole downhaul system. If your boat is older, it may have two stacked on top of each other. We now use the 7/16 thru-deck bushing in the kit which eliminates the need to differentiate between newer and older boats. This is also now the standard on all new racing Flying Scots. We will continue to offer this part for replacement purposes.
