Plexidor Security Pet Door frames are constructed with thick anodized aluminum that will not warp, bend, crack or rust. They are so durable that they are just about indestructible.
At the same time, precision engineering provides "gentler" benefits. These are quiet pet doors that will not bang shut, and they are easy to open with just a gentle nudge from even the tiniest pet. This is due to heavy-duty springs that are concealed within the frame.
