Unique connectors specifically designed by Southeast Sailboats for securely connecting Harken Carbo soft-attach blocks together. The unique cross-over design of these Dyneema soft shackles ensures that there is no force pulling at the head of the block. We offer two connectors – one for attaching two 29mm blocks together and another for attaching an 18mm block below the 29mm block. Breaking load in excess of 400Kg (estimated). Available in black. Blocks are not included!
