We bought a T.V. armoire that matches our bedroom group. We would like to put a clothes rod inside for extra closet space.

any that regire no hammer or screws? Also my old closet rod I still have up the hook (thing you slide the rod onto)

I have 2 bedroom closets that each have a slanted ceiling on one end. As you look into the the clostet, the slant is on the left. I want to install a clothes rod in each, but on the left/slanted side, there isn't anything to screw the rod holder end into. What can be done on the left/slanted side of the closet, so I can screw the rod holder in?
