Pet Door Trixie TRIXIE 3869 — Plastic Flap, White, Battery-Powered, Fits 1–3.5 cm Wall/Window

Trixie TRIXIE 3869 is a battery-powered plastic pet flap in white, designed for cats and small dogs. The unit is made for retrofit installation in doors, walls or windows with a compartment depth between 1 and 3.5 cm. It features a transparent, quietly operating flap with special sealing and a magnetic lock, a collar magnet for selective access and a safety lock. The set includes a tunnel element and is compact in size for straightforward mounting in existing openings.

Advantages

The lightweight plastic construction simplifies handling and installation while the transparent flap reduces visual obstruction. Magnetic locking combined with the collar magnet helps keep unfamiliar animals outside and permits controlled entry for pets wearing the magnet. The silent-action flap and special sealing reduce drafts and noise. The included tunnel element and the possibility to extend with additional tunnel elements allow flexible adjustment to wall or door thicknesses within the specified depth range.

How to use

Prepare an opening matching the specified cut-out dimensions and insert the tunnel element to achieve the correct depth. Fit the outer and inner frames and secure according to the mounting instructions. Install a 9 V battery in the compartment to power the magnetic lock mechanism. Attach the collar magnet to your pet’s collar so the magnetic lock recognises authorized animals. Use the safety lock when you want to prevent any entry or exit. Check the flap operation and sealing after installation to ensure smooth, quiet movement and proper closure.

Usage recommendations

For reliable operation, use a fresh 9 V battery and inspect the sealing regularly for wear. When installing in exterior doors, ensure the surrounding structure is weatherproofed to prevent drafts. If wall or door thickness exceeds the included tunnel length, add compatible tunnel elements to maintain proper fit. Periodically clean the transparent flap and check the collar magnet positioning to maintain selective entry function.
