No its not a guillotine, its a simple door!
Though it may operate like one, this is actually one of our most simplistic pet doors around. Operating off of 4 aluminum extruded channels, this door simply glides up and down as you need it to. The door itself is made of a high density polypropylene that makes this door waterproof and extremely durable. This is the same material that is found in laboratory and medical equipment due to its high heat tolerance and strength under pressure. This is a professional grade model for anyone looking for a simple and strong door.

Sizes:

• Regular: 14"W x 20"H
• Large: 18"W x 28"H

Installation is easy!

• Step 1: Place panel against wall as a template. Install each channel so the panel slides in its grooved track.
• Step 2: Drill hole or install a eye hook in panel. Install two pulleys to ceiling and attach a cable/rope to the 3/8" polypropylene panel.
• Step 3: Slide polypropylene panel in channels as needed.
