Series 57 blocks are available in numerous versions and are useful wherever a powerful compact multi-tackle is required.

The plain bearing Nova Blocks are two tone dark grey and take higher loads.

They are ideal for mainsheets up to 8.5m (28ft) yachts and smaller multihulls. The Cam arms have good adjustment for optimum cleating angle, whilst all beckets have removable pins to make rope take-off attachment easy.
