The Harken Carbo T2 Loop Block Single is an extremely lightweight block that is used wherever maximum performance and minimum weight are required. The low weight with high load capacity is achieved by dispensing with metal shackles or rivets and the consistent use of fibre-reinforced carbon composite. Delrin® ball bearings in the curved bearing shell ensure even dissipation of forces and maximum load capacity with minimal friction. The loop stop through the centre of the block directs forces directly to the disc, relieving the load on the cheeks and increasing the load capacity of the block. The loop, made of SK75 Dyneema® as an "endless construction", is pulled through the head of the block and threaded onto the anchor pin. Neither knots nor splices are necessary for installation and removal.
