The Harmony Yoke and Thwart Hardware Kit contains the same hardware as used in the factory when canoes are assembled. The kit includes 4 sets of stainless steel screws, finish washers, flat washers, and lock nuts. Designed to install yokes without any tendency to "rock" or work loose. Appropriate for IQ2, IQ, aluminum (on Royalex) or wood rails.
Bought this to replace the thwart, yoke, and bow seat on an old Old Town Tripper. Comes with 2 sets of finish washers, although they are not that different from each other except for a slightly wider rim on one set. Instructions recommend installing 4 sets of screws on a yoke (2 per side, to minimize rocking), so buying just 1 set turned out to be insufficient for also installing the thwart. Fortunately I was able to buy equivalents at my local Ace Hardware for about the same price, and put the other set of finish screws to good use.
As described. Great service
