Comments about Ronstan Series 40 All-Purpose Single Block:

These blocks are smaller, lighter and less bulkier than my older blocks that needed replacing.

      Comments about Ronstan Series 40 All-Purpose Single Block:

      I'm using two of these, attached to eye-bolts under my targa bar, for lifting a dinghy. They work great, plenty strong so far in testing.
      Great product for the price.
