Identical to the pulleys used in the YakGear Deluxe Anchor Trolley Kit, these Harken 290 pulleys are the perfect replacement part for any DIY project. The 2" x 1" x .5" pulleys are reinforced by long glass fibers for the realization of a compact pulley with a high strength/weight ratio. The sheaves spin bearings at high resistance with paths adjusted for a minimum coefficient of friction. The ball bearings, the sheaves, and the cheeks are treated with black carbon for superior UV resistance. The pulleys are sold in quantities of two. As always, the pulleys come complete with 4 (four) stainless steel 1-1/4" Pan Head Phillips screws and 4 (four) 5/8" wellnuts for paddlesport installation.
