Better measurements. Cleaner installs. Happier pets.
Start with the sizing guide, verify the technical opening, follow the model-specific manual and introduce the new door at the pet's pace.
Move from the pet to the product in four verified steps.
Each step answers a different question. Keep the outputs together so an installer, glass professional or future service person can follow the same record.
Measure the pet
Record shoulder height, body width and a comfortable step-over for every animal using the opening. Breed and weight ranges are a shortlist, not the final dimension.
Choose the model family
Door, wall, screen, in-glass, kennel and pass-through products are built for different surfaces. Select that family before finish or accessories.
Verify the building opening
Compare flap opening, rough opening and outer frame. Add wall depth, door construction, screen support or professional glass fabrication information.
Save the exact configuration
Record the final SKU, named size, finish, flap package, orientation and installation documents. That information is the key to future replacement parts.
Use the guide for the decision in front of you.

Use these answers to choose the right guide for sizing, installation, service parts or support.
Which guide should I read first?+
Start with the sizing guide, then open the installation guide for the surface you are cutting. Product-specific instructions should be checked again before installation.
Are the sizing guide and breed guide the same thing?+
No. Breed guidance helps shortlist likely sizes, but the sizing guide explains how to measure the individual pet and compare the actual flap opening.
Where do I find door, wall, glass and screen installation details?+
Use the surface-specific installation guides. Door, wall, glass and screen projects each have different pre-cut checks and risk points.
Do replacement flaps need a guide?+
Yes. Replacement flaps should match the installed model, named size, flap count and hardware relationship rather than only the visible opening.
Should I use guides before contacting support?+
The guides help collect better measurements and photos. If the opening is unusual, support can use that information to give a clearer recommendation.
Do these guides replace installer judgment?+
No. They help prepare the project, but hidden utilities, structural issues, glass requirements and local site conditions still need qualified review.
