Power Pet Patio PX1-SRE Regular Review: Sliding Door Pick
Sep 25, 2026
In this power pet patio px1-sre regular review, the Power Pet Patio PX1-SRE is the best sliding glass dog door insert for renters in our guide of 9 electronic dog doors, where it ranks number 6 overall. It is a motorized panel made by High Tech Pet that drops into an existing patio track, so you get automatic pet access with no cutting and no contractor. The panel measures 2 by 16 by 40 inches and weighs 45 pounds, and it fits track openings from 75 to 80.25 inches tall. As a medium unit it suits cats and dogs up to 30 pounds, which means a beagle or a corgi rather than a retriever. It sells for $769.99 and holds 4.3 stars from 38 Amazon ratings.
Automatic access starts with the MS-5 ultrasonic collar. Performance warranty coverage applies only when the Power Pet Patio PX1-SRE runs with authentic High Tech Pet MS-5 transmitters, so third party collars can void it. Directional sensing is the smarter part: the panel opens when your pet walks straight at it, not when it naps beside the door. Four modes on the control panel (In Only, Out Only, In & Out, and Locked) let you house train a puppy, lock everything at night, or send the cat out while the dog stays inside. Once the panel closes, a steel dead bolt throws automatically to block strays and intruders. On top of that, the auto retract safety system reopens the door if it meets an obstruction, which protects tails and paws. The aluminum frame and ABS panel handle a maximum compatible thickness of 2.5 inches.
The $769.99 price is the real hurdle. By contrast, several wall mounted doors in this guide cost less and handle bigger dogs than this 30 pound medium unit. However, none of them install in a sliding glass track without cutting, which is why the Power Pet Patio PX1-SRE earns the renter pick at number 6. The 4.3 star average from 38 ratings points to satisfied owners, though a small sample can hide fit problems. Two limits decide it: your track must fall between 75 and 80.25 inches, and your pet must stay under 30 pounds. Also, every pet needs its own MS-5 collar, which adds cost in multi pet homes. Even so, if you rent and want a locking motorized door this weekend, this is the one to get.
