Double-Decker Closet Rod
All you need to gain a lot of hanging space in your closet is two metal closet brackets and a length of closet rod. If your existing closet rod is at least 66 in. from the floor, there's enough space to add a second rod below it and still hang shirts and slacks. We placed the top of the rod 35 in. from the floor, which allowed just enough room to hang two levels of pants.
Locate studs on the back wall of the closet with a stud finder. Then attach metal brackets to the studs. Use a level to align the brackets along the top. Space the brackets no more than 32 in. apart.
