Attempting to attach Hanging Tool Rack

Is the wall bare studs, plaster, wallboard, or what? I'd screw a wide plank to the wall, being careful to hit as many studs as possible, even if the plank has to be longer than the plastic rack, and screw the rack off to that. Plank will help on any wall, but especially on bare studs, since it will keep the plastic from rotating into the stud space if you hang a heavy tool in the middle. If it is a plaster or wallboard finished wall, don't forget to put something on the wall below it to protect against dings and splashes from wet tools. (You do hose your metal tools off versus putting them away muddy, right?)

I'm planning on doing a similar rack in my garage, once I get around to taping/mudding/painting the half-ass wallboard job the previous owner did. A long 2"x8" plank lagged off to several studs, and farmer-style galvanized steel implement hooks screwed off to those. Another plank, high up on another wall, with bike hooks, since the ceiling is too damn high to reach for that, like I had done in previous houses.
