Overview
A telescoping frame carries the plastic flap and slides to match the thickness of the door it goes into. The two frame halves clamp together around the cutout, and the flap swings on its hinge for the pet to pass. A lock-out slide drops over the opening when the door needs to stay closed.
Large breeds get a wide flap and a frame that adjusts to fit doors of several thicknesses, so the same unit covers more installations. The slide gives you a way to shut the opening without removing the door. What limits it is the fixed flap size: a pet that outgrows the opening needs a different model, and the plastic build suits indoor doors rather than heavy exterior use.
Who it's for
Homes with a big dog that needs to come and go, or mixed households where a cat and a dog both use the same opening. Measure the widest part of the pet before ordering, since the flap size is fixed. Buyers wanting a metal frame or a door thicker than the stated range should look elsewhere.
Pros and cons
- Telescoping frame spans two door thicknesses
- Lock-out slide secures the opening
- Rated for large dogs up to the stated limit
- Works for cats and dogs together
- Flap size is fixed with no larger option
- Plastic frame is not a metal build
- Cutout template not listed
Performance notes
The flap swings on its hinge and returns to center after the pet passes, so the seal depends on the frame sitting square in the cutout. Telescoping halves need to be tightened evenly; an uneven clamp leaves a gap at the edge and the flap can drag. The lock-out slide is a cover, not a lock, so it stops the pet rather than a person.

Frequently asked questions
How do I know the extra large flap suits my dog?
The flap measures 10.5 by 15 inches and the door is rated for pets up to 90 pounds. Measure your dog at the shoulder and across the chest, then compare those numbers with the flap opening. A pet that measures near the flap size may still fit through but will have little clearance.
What door thickness does the Ideal Pet Products Designer Series door fit?
The telescoping frame is made for doors from 1.25 to 2 inches thick. The two halves slide against each other and clamp around the cutout, so the same unit covers that whole range. A door outside those thicknesses needs a different frame.
Does the lock-out slide keep the door shut?
The slide covers the flap opening so the pet cannot push through. It is a closure panel, not a locking mechanism, so it does not secure the door against a person. Remove or open the slide when the pet needs access.
Can a cat use this door if a large dog also uses it?
The listing covers both cats and dogs, and the flap is sized for large breeds. A cat can pass through the same opening, though the flap may need a push for a smaller animal. The lock-out slide lets you close the door when the cat should stay in.
What material is the Ideal Pet Products Designer Series pet door made of?
The frame and the flap are plastic, finished in white. The telescoping halves are part of that same plastic frame. The unit weighs 3 pounds and carries a one year warranty against manufacturer defects.
