The Nautos 92440 is a set of back to back blocks with a 1.10 in (28 mm) sheave. The working load is 310 lb (140.61 kg) and the breaking load is 2000 lb (907.18 kg). The length is 3.94 in (100 mm), rope up to 5 in (127 mm) is listed, and the weight is 0.10 lb (45.36 g). Those working and breaking figures are the ones to check against your line before choosing it.
Our take
A 28 mm sheave with a 310 lb working load and a 2000 lb breaking load describes a small block, so match your line's loads to the 310 lb working figure before you rely on it.
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.
