Product information

Description

Trixie 3870 is a tunnel element in white plastic designed as an accessory for compatible dog and cat doors. It functions as a connecting or extension part that increases the depth of a pet door installation by up to 25 mm per element, enabling a rigid, stable passage through doors, panels or frames. The component is intended for use with matching model series and fits where an added tunnel section is required to adapt to thicker doors or to create a defined opening for pet access.

Advantages

The accessory is made of durable white plastic that resists moisture and daily wear typical in household environments. Its modular design allows multiple elements to be combined to reach the required depth while maintaining a straight, stable tunnel for pets. The product is lightweight, easy to handle and can be integrated discreetly with compatible door systems to preserve the surrounding finish.

Suitable for

  • Extending the thickness of interior or exterior doors to accommodate a pet door
  • Creating a rigid tunnel section in doorframes, panels or walls
  • Adjusting installation depth when a single pet door element is not enough
  • Situations where a clean white finish is preferred to match door trim or interior décor

Key specifications

  • Material: white plastic
  • Depth extension: up to 25 mm per element
  • Designed for use as a tunnel/connecting element with compatible pet doors
  • Intended for indoor and doorframe installations

How to use

Measure the total door or panel thickness and determine how many tunnel elements are required to achieve a flush and secure installation. Fit the tunnel element between compatible pet door components according to the pet door manufacturer's assembly instructions, ensuring alignment and a continuous passage. Secure all parts with the recommended fasteners and check that the tunnel is stable and free from sharp edges before allowing pets to use the opening.

Usage recommendations

Use only with compatible Trixie pet door models or models specified by the manufacturer. Combine multiple elements when necessary to reach the needed depth, and inspect the assembled tunnel periodically for loose fittings or damage. Clean the plastic surface with a mild detergent and a soft cloth; avoid abrasive cleaners that could scratch the finish.
