Overview

This is an aluminum-framed dog door insert that fits into an existing sliding glass door track, adjustable in height from about 75 3/5 to 80 inches. It's rated for large dogs up to 75 pounds and uses a magnetic closure flap.

Insert-style doors like this replace one panel of a sliding glass door rather than requiring a cut into a wall or door, which makes it a reversible option for renters or anyone who doesn't want to permanently modify a door. The height range means it's built for a specific span of sliding door openings, so measuring the actual opening height before ordering matters more than with a wall-mounted flap door.

  • Height adjustable 75 3/5" to 80"
  • Aluminum frame construction
  • Max 1.5" frame thickness
  • Rated for dogs up to 75 lbs

Who it's for

Owners of large dogs, up to 75 pounds, who have a sliding glass door opening between roughly 75 3/5 and 80 inches tall and want a pet door without cutting into the wall or door itself. It won't fit doors shorter or taller than that range, or frames thicker than 1.5 inches.

Strengths and trade-offs

  • Adjustable height range fits a range of sliding door openings
  • Rated for large dogs up to 75 pounds
  • Magnetic closure flap

  • No reviews yet on flap durability

Performance notes

The insert slides into the existing door track in place of one panel, with the aluminum frame adjustable across the 75 3/5 to 80 inch height range to fit slightly different sliding door openings. The flap closes magnetically, and the frame is rated to fit door frames up to 1.5 inches thick, so measuring the frame thickness beforehand avoids a mismatch.
