This is a single swivel ratchet block from the Nautos Carbon Light line, fitted with an aluminum sheave. The sheave is 57 mm (2.24 in) across and the whole block weighs 107 g (0.24 lb). Its working load is 550 lb (249.4 kg) and its breaking load is 1200 lb (544.3 kg).
Our take
At 107 g with a 57 mm aluminum sheave, this is a light ratchet block, and its 249.4 kg working load against a 544.3 kg breaking load tells you what it is sized for. The swivel lets the block turn to follow the sheet.
From our buying guide
Ball-bearing blocks give the lowest friction on lines running under moderate loads. Plain bearings have more friction, but handle very high and static loads.
Check before you buy:
- A ratchet block is rated for the full sheet load.
- Any becket's load limit suits the job, since a becket can be rated below the block itself.
- A soft-attach block will be looked after, since Harken warns soft attachments are prone to wear and recommends them only for regularly maintained race boats.
