Unrivalled 18:1 holding power Dual sided On-Off switch Low friction ball bearing system Lightweight Cheek cut-outs for easy bearing maintenance Lockable swivelling head post High strength forged shackle Multi-position cleat arm The patented extruded hole design, in conjunction with the groove profile of the sheave, provides a more powerful grip than conventional designs - up to 18:1 holding power. Unrivalled low weight is achieved by the use of a Torlon° ratchet pawl, high grade machined alloy sheave and black Acetal hubs and bearings.
On-Off switching knob is fitted to both sides of the swivel blocks (one can be removed if desired), and for foot blocks simply turn the sheave upside down before installation to change the sense of rotation. Unique On-Off switch mechanism can be operated under load. Ratchet blocks can be disassembled for servicing or customisation.Removable becket pins allow lines to be pliced prior to fitting.
Saddle on under side of cleat can be used as a becket take off point for the creation of a powerful 6:1 purchase system. A Triple Block can be attached to the saddle to increase this to 7:1.
