Abstract: An adhesive interlocking mounting track for removably securing a sheet of semi-rigid or rigid material to a building structure. The mounting track is comprised of a base member and a locking member that snap together. When the two pieces are in engagement a retention channel is formed between then, for holding a relatively flat sheet of material. The mounting track is secured to the interior of a window or doorframe via a coat of adhesive on the back of an attachment plate portion of the base member. Thus the device is an easy to install material retention means. Additionally, it can be applied to the interior of a frame to recess the retained sheet of material and reduce its exposure to the environment.
