You'd like to install a pet door through your screen door but you have a protective grill in place! What to do? Ideal has created a pet door specifically for your situation. It's called the Ideal Screen-Guard Pet Door and it's just the ticket.
Available in white frame only and two sizes.
Note that Ideal's "XLarge" is really closer to what most would call a "large". See the size chart for specifics.
Incidentally, this pet door doesn't come with the screen guard! You provide that. But, once you have the guard, this is a pet door designed to go through it.
PLEASE NOTE: This product ships directly from the manufacturer and may take 1-3 business days before it actually ships.
