Cat Mate Microchip Cat Flap Wall Kit – 6 Tunnels & Wall Adaptor | Up to 370mm

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, blockwork and other deep masonry openings.

This kit includes 6 x 50mm Cat Mate tunnel extensions, giving 300mm of additional tunnel length. Combined with the approximately 70mm tunnel supplied as part of the Cat Mate cat flap, the system provides a fully lined passage of approximately 370mm.

A matching Cat Mate installation adaptor is also included. This provides a much neater finish around the wall opening and helps conceal the cut edges of brickwork, blockwork or masonry around the cat flap.

Complete Cat Mate Wall Installation Kit

Everything has been brought together into one package to make fitting a Cat Mate microchip cat flap through a thick external wall easier and neater.

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

Approximately 370mm of Fully Lined Tunnel

Each Cat Mate tunnel extension adds approximately 50mm to the total installation depth.

• 6 tunnel extensions: 300mm
• Cat flap integral tunnel: approximately 70mm
• Total available lined depth: approximately 370mm

You do not have to use all six tunnel sections. Use only the number required to suit the actual thickness of your wall.

Neat Finish Around the Brickwork

Cutting an opening through a brick or block wall can leave visible and uneven edges around the installation. The included Cat Mate installation adaptor provides a larger finishing surround around the cat flap.

This helps cover the cut edges of the brickwork or masonry and gives the finished installation a cleaner, more professional appearance.

Fully Enclosed Wall Tunnel

The tunnel extensions connect to the tunnel supplied with the Cat Mate cat flap, creating a smooth and enclosed passage through the wall.

This means your cat passes through a proper plastic-lined tunnel rather than coming into contact with:

• Cut brickwork
• Blockwork
• Cavity insulation
• Rough masonry edges
• Internal wall materials

The result is a cleaner, safer and more professional wall installation.

Suitable for Thick Walls

This wall kit is particularly useful for installations through:

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

Microchip-Controlled Entry

The Cat Mate Microchip Cat Flap is designed to recognise compatible registered microchips, allowing authorised pets to enter while helping keep neighbouring cats and unwanted animals outside.

This provides more control than a standard unrestricted cat flap and means a compatible microchipped cat does not normally need to wear a special collar key.

Ideal for Multi-Cat Households

Depending on the Cat Mate microchip model supplied with the kit, multiple pets can be registered to use the cat flap.

This makes the system suitable for both single-cat and multi-cat households where selective entry is required.

Manual Access Control

The Cat Mate microchip cat flap also provides manual access control, allowing you to restrict your cat's movements when required.

Depending on the model, access settings may include:

• Normal Access – allows everyday entry and exit
• In Only – allows your cat to enter but prevents them leaving
• Out Only – allows your cat to leave but prevents normal re-entry
• Locked – prevents access in either direction

Technical Information

How Many Tunnel Extensions Do I Need?

Each extension adds approximately 50mm of extra depth.

• 1 extension: 50mm
• 2 extensions: 100mm
• 3 extensions: 150mm
• 4 extensions: 200mm
• 5 extensions: 250mm
• 6 extensions: 300mm

Add this to the approximately 70mm tunnel already supplied with the Cat Mate cat flap when calculating the total installation depth.

Important Installation Information

Before cutting through any wall, check carefully for hidden services and structural components.

• Electrical cables
• Water pipes
• Gas pipes
• Structural supports
• Damp-proof membranes
• Insulation

For cavity walls, the tunnel should be kept level and securely supported so the tunnel sections remain correctly aligned.

Microchip Performance in Walls

Metal reinforcement, foil-backed insulation and some construction materials can interfere with microchip scanning performance.

Where possible, avoid positioning the microchip reader directly against large metal components or foil-backed materials and follow the Cat Mate fitting instructions carefully.

Can I Add More Tunnel Extensions?

Yes. Additional compatible Cat Mate 50mm tunnel extensions can be added if your wall is deeper than the capacity provided by the six sections included in this kit.

Can I Use Fewer Than Six Extensions?

Yes. You only need to install the number of tunnel sections required for your particular wall thickness.

Frequently Asked Questions

Can I add extra Cat Mate tunnel sections?

Will the wall opening be fully lined?

Yes. The tunnel sections join to the tunnel supplied with the cat flap to create an enclosed passage through the wall, helping cover exposed masonry, insulation and rough cut edges.

Why Choose the Cat Mate 370mm Wall Kit?

The Cat Mate Microchip Cat Flap Wall Kit with six 50mm tunnel extensions and installation adaptor takes much of the guesswork out of installing a microchip cat flap through a thick external wall.

The six tunnels and integral cat flap section provide approximately 370mm of fully lined depth, while the supplied adaptor helps hide cut masonry and gives the finished installation a much neater appearance.

For brick, cavity and insulated wall installations, it provides a practical combination of microchip-controlled access, a properly lined tunnel and a professional-looking finish.
