Flap Type


Door-mounted pet door that installs into standard doors for easy everyday access, combining a lightweight flap, clean and clear appearance, and reliable function for most climates.

The Liberty Pet Door for Doors is designed for simple, reliable access through a standard door. It creates a permanent opening for your pet while maintaining a clean, finished look on both sides of the door.

Built to Last Aluminum Framing
The frame mounts directly through the door, clamping securely between the interior and exterior sides. Once installed, it becomes a fixed part of the door, offering a stable and dependable solution for daily use.

Clear, Lightweight Pet Access
The lightweight flap is easy for most pets to push open, which is especially helpful for smaller dogs, cats, or pets that are hesitant with heavier doors. A magnetic closure helps guide the flap back into position after each use, supporting consistent alignment without added effort.

A slide-in locking cover gives you control when needed, allowing you to close off access at night or when leaving home.

This model prioritizes ease of use and accessibility over maximum insulation. It performs well in moderate conditions, but homes exposed to strong wind, extreme temperatures, or heavy weather may benefit from a more insulated upgrade.

Installation & Fit

  • Fits into most standard wood, metal, or hollow core doors with a cutout opening
  • Mounts through the door using an interior and exterior frame that clamps together
  • Secures with screws that fasten the frame tightly against both sides of the door
  • Includes a closing cover that slides into place to block access when needed
  • Requires basic cutting tools to create the opening in the door panel
  • Versatile design fits interior/exterior doors 1 1/8" to 1-3/4" thick

Best Suited For

Ideal for:

  • Homeowners looking for a permanent pet door installed directly into a door.
  • Interior or exterior doors where a clean, built-in look is preferred.
  • Mild to moderate climates where extreme wind resistance is not required.
  • Pets that benefit from a transparent, lighter, easy-to-push flap.
  • Households wanting a straightforward and cost-effective pet door solution.
  • Customers replacing an older or basic door-mounted pet door.
