Device promises art will be hung straight.

Need help in hanging those pictures just so?

The folks at Under the Roof Decorating say they have a tool that will come in handy.

The Hang & Level picture-hanging tool "ensures perfectly straight positioning each and every time, with absolutely no measuring or calculating involved," says a release from Under the Roof.

The tool has a "built-in level system" that ensures art will be straight, as well as rubber cushions designed to protect walls from scratches and nicks, the release says.

"That means no after-hanging hole patching or paint touch-ups are required. In addition, it works with all types of hanging hardware and allows decorators to use it by themselves."

The Hang & Level tool retails for $19.99, and is available at Home Depot, Canadian Tire, Lowe's and Bed Bath & Beyond. For more information, visit www.UTRdecorating.com.
