Overview
This is a pet door insert built for sliding glass doors, not a gate despite how it's filed. The panel adjusts from roughly 75 4/5 inches to 80 3/10 inches tall and is rated for dogs up to 75 pounds in the size L option.
Sliding door inserts like this fit into the track in place of a door screen, so the panel height range is the number that matters most: measure your actual door opening before ordering. No further spec sheet or seller copy was provided beyond the title itself.
- Sliding glass door insert, size L
- Adjustable 75 4/5" to 80 3/10" height
- Rated for dogs up to 75 lbs
- Model BSYTYMN01LW2
Who it's for
Households with a sliding glass door and a dog up to 75 pounds who want door access without cutting a permanent hole in a wall or door.
Strengths and trade-offs
Drawn from this product's published specifications.
- Adjustable height fits a range of sliding door openings
- Rated for dogs up to 75 pounds
- No cutting or permanent installation implied by the insert design
- No material, weatherproofing, or flap detail provided
- Fit is limited to doors within the stated height range
Performance notes
The insert's adjustable panel is meant to slot into an existing sliding door track, letting the door itself still open and close normally around it. Fit depends entirely on matching your door's height to the stated adjustment range.
