25mm Single Fixed Head Wire Block With Becket And Hook. Specifically intended for use where wire or rope lines are subjected to low running speeds and higher static loads.Becket РThis block has a becket to make tieing off easier. The becket also helps keep the load central and allows the block to be used in a purchase system.Hook Ð The hook is formed around the body so cannot be removed.Body Ð Formed in stainless steel for a lightweight yet robust frame.Bearings Ð A single row of spaced stainless steel ball bearings run on a stainless steel axle. This allows the width of the block to be as narrow as possible whilst still offering excellent rolling speeds and high working loads. For faster running, lower loaded control lines consider the dynamic range.
