The Mechanical Lock allows the release of hydraulic pressure on the backstay cylinder while maintaining tension. However, there is no relief valve protection, as backstay tension is mechanically locked, not hydraulically controlled. This is useful for extended passages.
Due to the wide variety of Upper Ends Fittings commonly used, A260 Mechanical Lock Cylinders are sold without them. Upper End Fitting Options include the Standard Aluminum Jaw Ass’y (A251-01-A), SS Jaw Ass’ys (H120), Lashing Eyes for Spectra Line (G703), Adjustable SS Turnbuckle Eyes (D540), Adjustable SS Turnbuckle Eyes w/ Toggle (D530), as well as a variety of Custom Options.
