Lockable Security Cover for Dog Doors and Pet Doors

To help us guide you to the right pet door and flap size, please include the following details in your message:

• A clear photo of the proposed installation area.
• Whether the door will be installed in glass, a timber door, weatherboard or a brick wall with a wall liner.
• The available space around the proposed opening, including any existing cut-out measurements if applicable.
• Your pet’s breed and, where possible, chest width, body depth, belly height and shoulder height.
• Whether you prefer an underbelly flap or a standard flap.
• For glass enquiries, tell us whether you know the glass type and thickness share a photo of the panel.

The more detail you provide, the easier it is for us to help you select an appropriate flap size and installation approach.

Glass pet door projects need to be assessed before a flap is selected. If your proposed location is a sliding glass door, fixed glass panel, window or double-glazed unit, send us a photo. Toughened glass and existing double-glazed units generally cannot be cut after they have been manufactured; the installation approach may depend on the glass type and the available panel space. 

Our Perspex pet doors includes spacers for your glass thickness.

Please do not arrange an opening in glass until the installation details and required flap size have been confirmed.

A suitable pet door is about usable flap space, not breed name alone. Measure your pet and compare those measurements with the flap dimensions below before choosing a size. If your pet has a broad chest, deeper body shape or a low underbelly, include those details in your enquiry so we can help you consider the available opening and flap style.

Our range includes both standard flaps with a square bottom and underbelly flaps with a rounded bottom. We also list specialist flap formats for Greyhounds, Whippets and Hungarian Vizslas. These names identify flap styles in our range; please use your pet’s actual measurements and the intended installation location when selecting a door.
