Works great on my ‘84 Hunter, 25.5’ sail boat. Correctly fits the slot in the mast. This item was not on the boat when I purchased it used and I must say, it is a game changer for keeping the sliders in the slot when raising the main sail. Highly recommend.

I ordered the wrong size so I ordered another smaller one. Although I made a mistake, the quality is good and I will keep the large one. I say large would fit a boat 30+ and I have a 25 foot sailboat so I will try again with a small one. Good product!

Perfect! Works just fine

Fits my C 30 perfectly and cheaper than Catalina Direct.

I have a 38' sailboat and it worked perfectly, I boat 2 as I know the first one will end up overboard like the original.
