Laser boom and traveler blocks made by Harken from stronger materials and ball bearings where needed. Available in a kit or individually.

The boom blocks and upper traveler block feature ball bearings allowing for faster mainsheet eases around the top mark. The traveler block is one piece - no more fussing with brummel hooks and shrink wrap!

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 you will need to do a little work.

We suggest using our Throughbolt Kit for Laser® Boom, which is available below and comes with plug kit and 5 fasteners (APS346). 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.
