It's a Must-Have
I had to install these twice, and here's why: My aluminum channel is from a different supplier and doesn't seem to offer enough of a "pinch" to keep the strap in tight. I installed the straps tight with about 6" left on each end, and they slid out from behind the spring wire after a few minutes. The fix was a matter of doubling the straps over the spring wire and installing an additional length of spring wire on top of that (as suggested by Tunnel Vision's experts). I also used a TEK screw on one that wasn't cooperating with me. I made sure to leave an extra foot or so on each end. I may end up trimming them all back, but we'll see. This product really makes a difference on my Solarig cover. I wouldn't install without them!
