Privacy with a dual purpose.
Color: Black, Size: 6 Panel-132'' Wide
While temporarily staying with family or friends, this portable wall offers some privacy and separation of personal space. It is easy to assemble and adjusts to different sizes by ordering different numbers of panels. While it provides a wall on one side, it serves as a place to add a little design and color to the inner space, as it is strong enough to hang a small quilt using clamps on the top rails. It also serves as a great hat rack for my husband’s many ball caps. I plan to continue to use it as a room decider, and to hide stored items from view. It truly makes the most of a small space.

Versatile!
Color: Grey, Size: 8 Panel-176'' Wide
Screen is more flexible than photo but folding it flat is challenging because of the supporting feet. I like the length of the screen; it divides a room in two, providing privacy and a walkway to back door. The screen can also be wrapped around the foot and one side of a queen size bed for privacy.
