ESP (Elegant Simple Products) is a line of hardware that complements our existing blocks in looks and function, but is simpler in design and construction.
These simple blocks with plastic sleeve bearings are perfect for high static loads. Their side load ball bearings deal with any misaligned loads and aluminium cheeks make them both strong and hard wearing. The swivel headpost lets block swivel to stop line from twisting. Harken pulleys can be proof tested and marked with safe working loads and serial numbers on request.
