This Harken ESP 57 mm footblock with cam cleat is a simple and robust block for sailboats where lines need to be led securely and locked when necessary.
The ESP series was developed as a functional supplement to Harken's other block series and combines a simple design with reliable construction for practical use onboard.
The sheave runs on Carbon Delrin ball bearings under lighter loads, while high static loads are handled by the large stainless steel center sleeve bearing.
