Side cheeks are made from marine grade aluminium grey anodised for durability.
The sheaves are precision turned from solid aluminium bar silver anodised and run on nylon bearings to reduce friction under load. Rivets are 316 grade stainless steel.
A simillar pulley in this range has a break load of 1750kg but the strength of this block will depend on its fixings. For maximum strength fixings should pass through the hollow centres of the rivets.
