This Nautos 92637 is a triple fixed block with a cam, a becket and an aluminum central sheave. It has a ball bearing ratchet that can be switched on and off while the block is loaded. The sheave is 75 mm across and the block takes line up to 12 mm. Working load is 748.43 kg and breaking load is 1360.78 kg. The block weighs 816.47 g.
Our take
A 12 mm maximum line size is the first figure to check on this triple block against your line. The ratchet can be switched on and off while the block is loaded, so it can be engaged or released without taking the load off.
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.
