Brand new from Harken! Laser boom and traveler blocks made from stronger materials.

Package includes both boom blocks and traveler block. The traveler block is one piece - no more fussing with brummel hooks and shrink wrap! These new blocks have less friction allowing for faster mainsheet eases around the top mark.

In order to install the boom blocks, you will need to remove both eye straps holding your current blocks on by drilling out the rivets. Upon reinstalling the eye straps with the new Harken blocks, we suggest using our Throughbolt Kit for Laser® Boom Block Eyestraps. Reinstalling pop rivets is not recommended as the holes may be enlarged by the drilling out of the original rivets.

Kit includes stainless steel nuts, bolts and washers for eyestraps, replacement gooseneck end boom plug and rivet (you will usually destroy the old plug while trying to remove it - plus a new plug gives a tight fit on the gooseneck pin), and special small diameter waxed twine.
