ABSTRACT:
A picture frame leveling tool includes an elongate, generally "L" shaped body formed with a horizontal and vertical defined leg defining a notch within the legs to accept a picture frame therewithin. Upper and lower visual level indicators enable alignment of the picture frame relative to a support wall surface. The organization optionally includes a friction cushion layer laminated to an interior surface of the horizontal leg to provide enhanced frictional engagement with the picture frame, and may further include capturing brackets slidably mounted to a rear vertical surface of the horizontal leg of the body to secure a picture frame within the notch during a leveling procedure.
