Overview
This is a large plastic dog door from PETCOMING (model FKSJDD2), rated for pets up to 100 lbs, with double magnetic flaps and an included closing panel, designed to install in interior or exterior doors or a wall.
The double magnetic flap is the main functional detail here, meant to help the door reseal after a pet passes through, and the closing panel lets an owner block the opening entirely when needed. Compatibility depends on door thickness: the listing specifies a fit range of about 1.02 to 2.36 inches, so it is worth measuring the door before installing.
- Large size, up to 100 lb pets
- Double magnetic flaps
- Includes slide-in closing panel
- Fits door thickness 1.02 to 2.36 inches
Who it's for
Well suited to owners of large dogs, up to 100 lbs, who want a plastic rather than aluminum door that fits a standard interior or exterior door within the 1.02 to 2.36 inch thickness range. Not a fit for unusually thick doors or walls outside that range, or for anyone wanting a metal frame.
Strengths and trade-offs
Drawn from this product's published specifications.
- Rated for pets up to 100 lbs
- Double magnetic flaps for a tighter reseal
- Includes a slide-in closing panel to block the opening
- Installs in interior or exterior doors or a wall
- Only fits doors between about 1.02 and 2.36 inches thick
- Plastic frame rather than metal
Performance notes
The double magnetic flaps work together to reseal the opening after the pet passes through, cutting down on draft compared to a single flap design, while the slide-in closing panel lets the opening be fully blocked when the door is not in use.
