It seems that my down haul cleat slides up and down the luff track in the main without any difficulty. I've been trying my best to downhaul and cleat on the main halyard cleat, but you know that doesn't work very well.

I thought I would post here (searched, but found no topic on this) to see if there was some good solution to fixing this problem. I haven't looked at it too closely because I was short on time when I noticed it and had to get on the water.

Is it riveted or screwed into the mast? I have a 1980 vintage 16. Thanks for any help.
