PetSafe Staywell 940 Tunnel Extension for 919 Cat Flap

The PetSafe Staywell 940 Tunnel Extension is a genuine extension section designed specifically for the PetSafe Staywell 919 Classic Cat Flap.

Each tunnel extension adds approximately 18mm (¾") to the installation depth, making it useful when fitting the Staywell 919 into thicker doors, panels or walls.

Multiple 940 tunnel sections can be connected together, allowing you to build up the tunnel to suit the depth of your installation while creating a much neater enclosed passage through the door or wall.

Designed for the Staywell 919 Classic Cat Flap

The Staywell 940 is manufactured specifically as a tunnel extension for the Staywell 919 Cat Flap.

• Compatible Model: Staywell 919 Classic Cat Flap
• Tunnel Model: Staywell 940
• Additional Depth: Approximately 18mm per section
• Colour: White
• Quantity: 1 tunnel extension

Please check that your existing cat flap is a Staywell 919 before ordering. Staywell has produced many different cat flap models and tunnel extensions are not interchangeable across the complete range.

Adds 18mm of Tunnel Depth

Each Staywell 940 extension adds approximately 18mm (¾") to the tunnel length.

If additional depth is required, several sections can be connected together:

• 1 tunnel extension: approximately 18mm additional depth
• 2 tunnel extensions: approximately 36mm additional depth
• 3 tunnel extensions: approximately 54mm additional depth
• 4 tunnel extensions: approximately 72mm additional depth
• 5 tunnel extensions: approximately 90mm additional depth

You only need to use the number of extensions required for the thickness of your particular installation.

Ideal for Thicker Doors and Panels

The Staywell 940 tunnel extension is particularly useful where the standard tunnel of the 919 does not completely cover the depth of the material into which the cat flap is being installed.

Typical applications can include:

• Thicker timber doors
• uPVC door panels
• Composite panels
• Wall installations
• Other deep openings suitable for the Staywell 919

Neater Wall Installations

When a cat flap is installed through a wall, leaving the inside of the opening exposed can result in visible brickwork, blockwork or other building materials.

Using the correct tunnel sections creates a smooth plastic-lined passage through the opening and gives the installation a considerably cleaner finished appearance.

The tunnel also helps prevent your cat coming into direct contact with rough edges and exposed materials inside the opening.

Connect Multiple Staywell 940 Tunnels

The extensions are designed so that multiple sections can be joined together when greater depth is required.

This makes the system flexible because you can build the tunnel to approximately the depth needed rather than having one fixed-length extension.

How Many Staywell 940 Tunnel Extensions Do I Need?

First measure the total depth of the door, panel or wall where the Staywell 919 is being installed.

Then determine how much additional tunnel length is required beyond the tunnel already provided by the cat flap. Allow approximately 18mm for each Staywell 940 extension.

For example, if you need approximately 54mm of additional tunnel length, you would normally require three 940 tunnel extensions.
