The Harken 2169 is a Power3 ratchet block with a shackle head and the silver 2x grip, rated at 20:1 holding power. The on/off switch works from both sides. It carries a 500 lb (227 kg) maximum working load and a 2000 lb (907 kg) breaking load, takes line up to 3/8 inch (10 mm) and weighs 3.0 oz (85 g). The maker points this grade at strong, steady wind.
Our take
The 20:1 holding power is double a standard ratchet, and the maker points it at strong, steady breeze. The on/off switch can be reached from either side of the block, so you can turn the ratchet off without hunting for the right face.
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.
