Series 45 Blocks are available in numerous versions including a matching ratchet block.
The ball bearing Macro range are freer running and have black sideplates and sheaves whilst the plain bearing Nova Blocks are two-tone dark grey and take higher loads. The multiple head units are shown in more detail on Block Features page together with technical information on how to choose blocks for your application.
They are ideal for mainsheeting on dinghies and dayboats and general sheeting on smaller cruisers. The Cam arms have good adjustment for optimum cleating angle whilst all beckets have removable pins to make rope takeoff attachment easy.
The Snapshackle unit R7475 fits any of the 10mm pillar blocks to convert them to a one-handed operation swivel block.
