This was very easy to assemble and required you to mount the main mounting bar directly into studs with 4 1/4 inch wood screws. If you extend 6' you can run this main to full extension and it supports a lot of weight. It's handling a rack that went the full 10 feet of my closet with a 6 foot header and 4 hanging stations. Also keeps all of her Louie's on top of the unit in a nice storage area that extends about a foot to the ceiling. She is a brat so you don't have to own Louie's to do this :-)
