Spring loaded arm for precise and reliable locking operation- the spring holds the arm in open or closed positions. Quick Lock function is intended for temporary use only, and does not replace a normal clutch or a cleat. Acetal sheave.  Torsionally rigid cheeks in glass fibre filled composite prevent jamming of the line. Radial loads are absorbed by a stainless strap inside the cheeks.
