QUICK LOCK

Techical features

• Spring loaded arm for precise and reliable locking operation. The spring holds the arm in open or closed positions.
• The Quick Lock function is intended for temporary use only, and does not replace a normal clutch or a cleat.
• Acetal sheave (PBB 60).
• Glass fibre reinforced sheave with polymer bushing (PBB 80).
• Torsionally rigid cheeks in glass fibre filled composite prevent jamming of the line.
• Radial loads are absorbed by a stainless strap inside the cheeks. A safety feature quite typical for Seldén products.
