Abstract: A modular panel mount strip for mounting a panel or piece of art to a wall comprising an elongate body and a magnet. The elongate body includes a magnet housing, a segmentation groove, and at least one interlocking feature. The magnet housing retains the magnet within the elongate body. The segmentation groove is located between a top edge of the elongate body and a bottom edge of the elongate body and can be structured and configured to be broken by human force without breaking other parts of the elongate body. The interlocking feature includes a hinged portion on a first end of the elongate body and/or a locking portion on an opposing end of the elongate body. The locking portion of a first modular panel mount strip can interlock with the hinged portion of a second modular panel mount strip, thereby creating an interlocking mechanism and lengthening the overall device.
