Harken Carbo Ratchet Block

From the Harken Carbo range the ratchet block is a highly popular and successful piece of kit. Providing extra purchase and precision control, it is an ideal main sheet block. The 57mm block has 10:1 holding power which reduces effort required for the end user. The ratchet can be turned off from either side of the block and, like the rest of the Harken Carbo range, the block has been designed to produce high strength and low weight at a sensible price.  The Harken Carbo range of blocks claim to be 60% stronger and 30% lighter than the classic Harken block.

The high load 57mm ball bearing block not only looks the part but has been designed with strength and longevity in mind. Nylon resin side plates use a system of densely packed long glass fibres for a high strength to weight ratio. The sheave spins on high-load ball bearings with fitted braces for low-friction use and the sideplates have been UV stabilised for added protection.
