Cat Mate Microchip Cat Flap Wall Kit – 5 Tunnels & Wall Adaptor | Up to 320mm

The Cat Mate Microchip Cat Flap Wall Kit is a complete solution for installing a microchip-operated cat flap through brick walls, cavity walls, insulated walls and deep masonry openings.

This kit includes 5 × 50mm Cat Mate tunnel extensions, providing 250mm of additional tunnel length. Combined with the approximately 70mm integral tunnel supplied as part of the Cat Mate cat flap, the complete system provides a fully lined passage of approximately 320mm.

A matching Cat Mate installation adaptor is also included. This provides a larger finishing surround around the cat flap, helping to conceal the cut edges of brickwork, blockwork or masonry and create a much neater finished installation.

Complete Cat Mate Wall Installation Kit

Everything required for a professional Cat Mate microchip cat flap wall installation has been brought together into one convenient package.

• 1 × Cat Mate Microchip Cat Flap
• 5 × 50mm Cat Mate Tunnel Extensions
• 1 × Cat Mate Wall Installation Adaptor
• Installation components supplied with the cat flap
• Cutting template where supplied
• Installation instructions

Suitable for Walls up to Approximately 320mm Thick

Each Cat Mate tunnel extension adds approximately 50mm to the available tunnel length.

• 5 × 50mm tunnel extensions: 250mm
• Cat flap integral tunnel: approximately 70mm
• Total available lined depth: approximately 320mm

You do not have to use all five tunnel extensions. The number of sections can be adjusted to suit the actual thickness of your wall.

Fully Lined Tunnel Through the Wall

Rather than leaving the inside of the wall opening exposed, the Cat Mate tunnel extensions join together with the cat flap's integral tunnel to create a smooth, enclosed passage through the wall.

This helps prevent your cat from coming into contact with:

• Cut brickwork
• Rough blockwork
• Cavity insulation
• Sharp masonry edges
• Internal wall materials

The result is a cleaner and more professional installation with a proper plastic-lined route through the wall.

Wall Adaptor for a Neater Finish

Cutting a cat flap opening through brick or blockwork can leave rough or uneven edges around the opening. This kit includes a Cat Mate wall installation adaptor to provide a larger finishing surround around the cat flap.

The adaptor helps hide the cut edges of the brickwork or masonry, giving the installation a much cleaner appearance and reducing the amount of visible making-good required around the opening.

Microchip-Controlled Entry

The Cat Mate Microchip Cat Flap is designed to recognise your cat's compatible implanted microchip, allowing authorised cats to enter while helping to prevent neighbouring cats and other unwanted animals from gaining access to your home.

This provides your cat with independent access without requiring a collar or conventional magnetic key where a compatible implanted microchip is used.

Ideal for Brick, Cavity & Insulated Walls

The 320mm wall kit is particularly useful where a standard cat flap tunnel is nowhere near deep enough to span the complete wall.

Suitable applications include:

• Brick external walls
• Blockwork walls
• Cavity walls
• Insulated cavity walls
• Timber-framed walls
• Rendered walls
• Deep masonry openings

Important Installation Information

Before ordering, measure the complete finished wall thickness carefully. The approximately 320mm maximum lined depth is based on the five 50mm extensions plus approximately 70mm provided by the cat flap's integral tunnel.

Before cutting into any wall, always check for concealed electrical cables, water pipes, gas pipes, structural supports, insulation and damp-proof materials.

The tunnel should be installed level and securely supported so that all sections remain correctly aligned and provide a smooth passage for your cat.

Frequently Asked Questions

How thick a wall will this Cat Mate kit fit?

The five 50mm tunnel extensions provide 250mm of additional depth. Combined with the approximately 70mm integral tunnel on the cat flap, the kit provides approximately 320mm of total lined tunnel depth.

Do I have to use all five tunnel extensions?

No. Use only the number of 50mm tunnel sections required for your particular wall thickness.

What does the wall adaptor do?

The installation adaptor provides a larger finishing surround around the cat flap. It helps conceal the rough or cut edges of the brickwork or masonry and gives the completed installation a much neater appearance.

Does the tunnel cover the inside of the wall opening?

Yes. The tunnel extensions connect together to create a smooth plastic-lined passage, helping prevent your cat from coming into contact with exposed brickwork, insulation and other materials inside the wall.

Can this kit be used in a cavity wall?

Yes. The kit is particularly useful for cavity and insulated wall installations where a longer enclosed tunnel is required.

What if my wall is thicker than 320mm?

A kit with 6 × 50mm tunnel extensions is available for deeper walls, providing approximately 370mm of total lined depth.
