Maybe you'll have better luck than I did, but I wasn't happy with mine and ended up ripping it off and throwing mine away after a few years. The tracks kept jamming up and parts would break. The customer support was subpar at best. Even though it was broken after the first 7 months..... Seem to remember something about "Limited Warranty" even though a year or more was stated.
I should have just stuck with the Undercover Liner that I bought for my 2005 Tundra, but I thought the Roll N Lock would give me better access for taller loads that wouldn't require removal of the tonneau for my newer Tundra.
After I chucked the Roll N Lock I bought some other flip type I can't even remember the name of for my 2010 Tundra (The blue truck pictured). It's okay and does the job, but it's heavy and You don't want to have to remove it, or reinstall it. It also only opens as far as shown so you lose three feet of cargo if wanting to haul something taller than the cover.
The Undercover (Red truck pictured) is made of heavy duty ABS plastic that I can walk on top of at 250 lbs, but I can easily lift it off the bed by myself if I need to remove it because it's light, though a little awkward due to size. I can remove the cover in about 2 minutes easily with the quick disconnect gas shocks and clips at the hinges next to the truck cab. I'm sure they've made improvements in design since I've bought mine in 2006, but I wouldn't know for sure. The only issue I've had was the gas springs wore out about four years ago and it wouldn't stay up on its own. I seem to remember it costing about $75.00 to replace them with shipping.
It also was the most economically priced of the three I've bought!

Don't know about this company, but it had the best picture to give you an idea.
