I have these sliders as well.
Originally I mounted them incorrectly (the upper bracket bolt). The true mounting location is at the front LOWER location (Picture a Reversed capital "L" and mount at the 90 degree bend). There is an Allen bolt on the right side and a normal hex head on the left. You must remove your side panels to get access to these locations.
And FYI, while I was burning the tire off this weekend (in prep for the new one today), I found out they work rather well when I dropped the bike on the right side....cases didn't even come close to the ground......
By the way. That picture shows the incorrect mounting location. From that spot, they will protect very little and probably break the brackets on impact.
