Stainless

The Harken 234 is a 22 mm Micro block that attaches by shackle. Micro blocks are small and light and run freely. The side plates are stainless steel and the bearings are Delrin balls. The shackle pin is 3/16 inch in diameter. Harken lists it for cunninghams, outhauls, vangs, traveler controls and barberhaulers, among other light control jobs.

Our take

The shackle attachment on this 22 mm Micro block pairs with stainless side plates and Delrin ball bearings in a small free running body. Harken names cunninghams, outhauls, vangs and traveler controls as its jobs.

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.
