    Comments about Series 40 All-Purpose Blocks:

    I use the single block to run my furler line from the starboard deck into the cockpit. Cheaper than other brands but I can't see any difference in the quality. Only negative is the shackle requires a screwdriver, it has a screw head unlike other brands which can be tightened by hand.

      If you are a recreational sailor this product strikes the right balance between quality and price. I use several of them for control lines on my 25ft. Freedom.
