I’ve used them before. Super handy, but if you apply too much pressure it has the power to cause the bedside to deflect, especially if you place it high in the bed.
Doesn’t work with the cover I bought
I use mine with a retrax cover and factory bed rails. I trimmed the divider rails at the back, close to the retrax box.
That one wouldn't work with my cover either so I ended up going with this set up. It folds down flat quite easily so you can use the whole bed without removing it if you need to. It's called Truck Bed Slide Stop. I just got it so will see how it works out.
I have been using them for the last few years in my trucks. If you are going to get the bar type then that is the only brand worth buying in my opinion. Very stout and does its job very well.
Ah that sucks! What cover are you using?
I know this wasn't directed to me but it didn't work with my cover either which is the Undercover Amorflex.

Trucker's call them load-locks. Practically every single enclosed semi-trailer you've ever seen on the road is running some variation of them for securing freight. They work great, as long as you find the sweet spot in between too loose to secure your cargo, and too tight resulting in bed damage. Only downside in my opinion, is they are bulky to store when not in use.
