Trailer Slides

[Zom]

I'm looking for the low profile trailer slides for a 12' trailer. I did a search & saw the suggestions for using an old bed liner, but I think I want to spend the money & get the low profile ones. I would prefer a 1 piece unit per ski, or a 10' section with a 2' section at the end. I don't want to tack a bunch of 5' sections together.

Does anybody here sell them? I would prefer to support members from the forum before buying from some internet store.

Thanks
