Harken Laser Aft Boom Block with Becket from Laser Performance.
Laser Performance has brought us a great Harken upgrade with these Laser blocks. The boom blocks and upper traveler block feature ball bearings - 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. When reinstalling the eye straps, they may either be riveted back in place - or to make installation a breeze, check out the APS Throughbolt Kit.
