Series 57 blocks are available in numerous versions and are useful wherever a powerful compact multi-tackle is required.
The ball bearing Macro range are freer running and have black side plates and sheaves.
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.
