I have for sale a pair of Harken 75mm foot blocks, they have been fitted to the boat for less than 30 miles but decided they wanted the lock off version they were use to. They come with new pads as we reused to existing ones.
These are £118.05 each new and I'm looking for £90 for a pair of them, plus shipping cost and PayPal fees if necessary.
Below is the description from the Harken site, the sizes and working load is in the photograph (it's the 6092 line).
Harken Foot Block-75MM ESP 6092
Harken's ESP line (Elegant Simple Products) complements other Harken blocks in look and function but the blocks are simpler in design and construction.
Sheaves feature axle bearings to handle high static loads. Use ESP Footblocks for reef lines and genoa sheets where the angle is not extreme.
In a stacked configuration, the upper block will have a safe working load and breaking strength of 2/3 of a standalone single.
