Amazing. These make securing your sleds extremely fast.
I purchased two of these for my new inline trailer that did not have tie down points. I added sections of Supertac through bolted and the entire system is great. I can tie down both sleds in a matter of seconds. And the sleds don't move an inch. They are expensive, but very much worth the investment.
The Super clamp II Tiedown is a great addition to my trailer, very handy and nice. I certainly like the way it works. I also must compliment Dennis Kirk on the great service. I ordered it at around 5 PM and had it the next day. Not the first thing I have bought from them but just saying the service is awesome.
I bought two of these. They work really well. I used to hate spinning the screw-in type ski holders, especially when it was cold out. After you get these set up, takes seconds to put them on. Musch faster than what came on my Karavan trailer.
