ABSTRACT:
A hands-free level for gauging structural-member orientation. The level includes an elongate frame with two side-faces and at least one main reference surface extending therealong and having a mainwidth, a level indicator secured to the frame, and a support arm to facilitate holding of the reference surface against the stud. The support arm has a proximal end and extends to a free distal end which includes an end member. The proximal end is pivotably secured to the frame about a pivot axis such that the distal end and end member are movable between a storage position along one of the side-faces and a use position beyond the reference surface and stud. A coil spring is about the pivot axis biases the distal end and end member to the storage position. The end member extends from the distal end and terminates in a stud-engaging portion. When the reference surface is against a stud surface, the stud-engaging portion engages the stud for hands-free holding of the level thereagainst.
