XLarge Openable Pet Door for Sliding Glass Doors, Adjustable

The Verdict

If you’ve priced out a professional sliding glass door pet door installation, you already know it’s a $500-plus job. This XLarge openable panel from the folks at PetSafe-adjacent budget territory comes in at a fraction of that, and it solves the biggest problem with traditional pet doors: it doesn’t require cutting a hole in your actual door. But a 3.6-star average across 180 ratings tells you this isn’t a slam dunk. Here’s what you need to know before you buy.

What You Actually Get

The package includes the main aluminum frame panel with a center flap, two telescoping side panels to adjust width, weatherstripping strips, and mounting screws. The flap itself is a thick, flexible vinyl that hangs from a top hinge with magnetic strips along the bottom edge to keep it sealed when not in use.

The “openable” feature is the headline: the entire center section swings open on a side hinge, so you can walk through with groceries, let a delivery person in, or move furniture without stepping over the flap. That’s genuinely useful and something most fixed pet doors don’t offer.

Real-World Performance

The install is straightforward — you slide the assembled unit into your existing door track, tighten the tension screws, and close your glass door against it. No drilling into the glass door itself, no permanent modification. Most buyers report 20-30 minutes to install. As one verified buyer put it: “Took me longer to get it out of the box than to put it in the track. Fits perfectly in my standard sliding door.”

The flap works well for medium and large dogs. The magnetic closure keeps it sealed against wind and most weather, though it’s not fully airtight. The XLarge opening is roughly 12 x 17 inches of flap space — plenty for a 70-80 pound dog. The adjustable width is the real selling point here, accommodating tracks from about 26 to 38 inches wide.

Where It Falls Short — Read This Before Buying

The 3.6-star rating is earned. The most common complaints cluster around three issues:

The threshold lip is a genuine problem. The bottom frame sits about 2 inches above your floor level. That’s a real hurdle for senior dogs, arthritic pups, or short-legged breeds like Corgis and Dachshunds. Multiple reviews mention their older dogs simply refusing to use it. One reviewer noted: “My 12-year-old Lab can’t clear the lip. She just stands at the door and whines until someone opens it for her.”

Frame edges are sharp. The aluminum panels join with visible seams that have unfinished edges. Several buyers report cutting their hands during assembly. This is a design flaw that should’ve been caught in quality control.

Fit isn’t universal despite the “adjustable” claim. Track depth varies between manufacturers, and this panel is built for standard 1-inch to 1.75-inch deep tracks. If you have a non-standard track, you’ll find the tension screws don’t seat properly, and the panel wobbles or gaps at the bottom.

Who Should Buy This

Buy it if: You have a large, healthy dog (40+ pounds), a standard sliding glass door track, and you want a reversible pet door solution that doesn’t damage your property. Renters especially benefit — you can remove it and leave no trace when you move.

Skip it if: You have a senior dog, a small/arthritic breed, or a non-standard door track. Also skip if you live in extreme climates — this panel provides minimal insulation compared to a professionally installed door with a sealed frame.

FAQ

Q: Will this work on a 3-panel sliding door? A: No. This is designed for standard 2-panel sliding doors only. The telescoping panels adjust width, not the number of tracks.

Q: Can I lock it so my dog can’t go out at night? A: The flap itself doesn’t lock, but the entire center panel can be closed and latched, effectively sealing the opening. You just can’t lock just the flap.

Q: Does it come with a cover for when the door isn’t in use? A: No. If you remove the panel, the glass door slides directly into the track as normal. There’s no separate cover piece.

The Verdict

Rating: 3.7/5 — A solid budget solution for the right dog and the right door.

The XLarge Openable Pet Door delivers exactly what it promises for a specific use case: a large dog, a standard sliding door, and a renter who can’t modify their property. The openable center panel is a genuinely thoughtful feature. But the raised threshold, sharp edges, and inconsistent fit for non-standard tracks drag it down. If your dog is young, large, and agile, and your track is standard, this is a smart buy. If any of those conditions don’t apply, keep shopping — or budget for a professional install.

Price check: This typically runs $80-$120 depending on current Amazon pricing. Given the quality and the 3.6-star track record, that’s a fair price for what you get — but not a steal.
