The Nautos HT92210 is a single block with a swivel head and a 57mm sheave. The cheeks and axle are 316 stainless, and the maker lists acetal resin and high load aluminium for the rest. It takes line up to 12mm. The listed safe working load is 210 kg and the break load is 1080 kg. The block weighs 125 g.
Our take
A 210 kg working load against a 1080 kg break load tells you how much margin the maker allows, and the 316 stainless axle and cheeks are listed outright. Keep line to the 12mm maximum on the 57mm sheave.
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.
