Query: I HAVE A QUESTION BUT DON'T KNOW WHO TO ASK!

WELL, THIS SOUNDS LIKE A GREAT PRODUCT, AND I AM NOT A PRO AT INSTALLING THINGS BUT, DOES ANYONE KNOW WHO I WOULD ASK THE QUESTION "CAN IT BE MOUNTED ON THE RAFTERS OF THE GARAGE IF THEY ARE SLANTED? AND WILL THE RACK THEN BE LEVEL TO HOLD STUFF? I DON'T KNOW IF THE CABLES ARE SELF-LEVELING OR NOT. HELP/ RUSSRacor Pro HeavyLift 4-by-4-Foot Cable-Lifted Storage Rack #PHL-1R
