This is a great system overall. I agree with the others that the length of the 48" rails do not work well with the the typical 16" stud spacing. You shouldn't have to angle the screws to hit the studs as the Rubbermaid representative as been saying in these comments. When I installed mine, i centered the rail on the middle of 3 studs, and screwed into the 3 studs. That left an 8" overhang beyond the studs on each end of the rail, for which I used 2 drywall anchors (one top and bottom) at the last holes at each end of the rail. I will not be hanging anywhere near the rated weight, so this configuration works very well. I ended up butting 2 or 3 of these rails end to end, and this configuration worked very well for that as well.
