SureFlap Cat Door Tunnel Extender, White, Modular Extension for Thicker Installations

SureFlap Cat Door Tunnel Extender is a white accessory that adds tunnel depth to compatible cat doors, with a modular design for connecting multiple extenders.

• Fits SureFlap Cat Door Connect, SureFlap Cat Door and SureFlap DualScan Cat Door — match the extender to one of these door models.
• Designed for thicker installations — adds tunnel depth where the installation needs it.
• Multiple extenders connect together — supports a modular setup.
• One tunnel extender included — provides the component for extending a compatible door tunnel.
• White finish and durable construction — the extender is made for long-term use.

When a cat door installation needs more tunnel depth, this accessory provides an extension for select SureFlap models. It is intended for thicker installations and offers a modular option for setups that need more than one extender. The key buying check is compatibility: this extender is designed for three named SureFlap cat doors, rather than cat doors generally.

Which cat doors does the SureFlap Tunnel Extender fit?

It is compatible with the SureFlap Cat Door Connect, SureFlap Cat Door and SureFlap DualScan Cat Door. Compare the name of your cat door with this model list before choosing the extender. Its role is to extend the tunnel depth of a compatible door, making it suitable when the installation is thicker and needs additional tunnel depth.

• Compatible model: SureFlap Cat Door Connect.
• Compatible model: SureFlap Cat Door.
• Compatible model: SureFlap DualScan Cat Door.

Can I connect more than one extender?

Yes, the modular design allows multiple tunnel extenders to be connected. This gives you the option to build an extension using more than one extender for a custom installation. The product information identifies the compatible door models but does not give a specific extension depth, so choose based on your installation’s need for added tunnel depth.

• Connect multiple extenders for a modular setup.
• Designed to support custom installations.

What comes with the extender?

The package contains one SureFlap Cat Door Tunnel Extender in white. It is the tunnel-extension component for a compatible cat door, rather than a cat door itself. The stated purpose is to increase tunnel depth; no particular installation method or tools are specified.

• Quantity: one tunnel extender.
• Colour: white.
• Construction: described as durable and built for long-term use.

This extender suits owners fitting a SureFlap Cat Door Connect, SureFlap Cat Door or SureFlap DualScan Cat Door in a thicker installation, as well as custom setups that use connected extenders. Its specific function is to add tunnel depth to those compatible cat doors.
