The Wall Liner for Cat Mate
Is Used to "Frame Out" a Wall For a Cat Mate Cat Door Models 234 and 235.
In a wall pet door installation, it's vital that the wall be framed out and this is an easy way to get it done. Wall liners join together in sections to form a tunnel. Each wall liner section adds 2" to the over-all tunnel length. Purchase only enough to reach within 2" of the complete thickness of the wall as the cat door itself will add 0" to 2" to make a tight fit.
Please note that all wall liners come in white only. They can be painted if desired.
We've noted elsewhere that installation of a pet door through a wall is not a trivial task. We think a licensed contractor is the safest method to avoid injury and prevent water leaking into the wall.
Cat Mate is also Marketed as 'Pet Mate' and 'Ani-Mate'.
