If anybody, like me on my 2009 Beneteau Oceanis 31, was thinking of fitting the Barton 32mm track cleats amidships, I'm sorry to say they won't fit the Lewmar track as supplied by Beneteau. My excitement at tracking down a Barton cleat didn't last long when I found that the slot, although the correct size for purely the track, does not have enough clearance over the non-flush track bolts. What a pity Barton haven't oversized the slot and fitted nylon sleeves like the Lewmar cars. Grinding out a 2mm relief might work but will conflict with the plunger, and increasing the slot depth might also work but would allow the cleat to rattle.
