Adjustable system designed to hold an interior door cracked open just enough so that smaller pets such as cats can go in and out. (To access food or litter box) but larger pets and children cannot. Simply remove existing door strike plate from the door jam and install Door prop using existing screws.

Slide both pieces together then insert the bolts (M3x12mm) through both parts and put a nut (M3) on the back of each bolt.
