Also Using Bottom Risers?

Bottom Risers are designed to raise the flap height for taller pets, making it easier for them to comfortably use the Mesh Patio Pet Door.

Because a Bottom Riser sits beneath the pet door, it also increases the overall installed height by 75 mm (3"). If you plan to use one or two Bottom Risers, remember to include this additional height when checking whether your sliding door opening is suitable.
