Give your pet convenient indoor and outdoor access with the Hakuna Pets Medium Glass Patio Pet Door, a sliding door insert featuring an adjustable frame height from 77.2 in. to 83.5 in. for compatibility with many patio doorways. The pet flap measures approximately 8.9 in. wide by 12.4 in. high and includes a magnetic centering catch that helps the flap close after each use, while the included locking panel lets you restrict pet access when needed. Crystal-clear tempered glass panels preserve outdoor visibility, and the lightweight, rust-resistant aluminum frame provides durable everyday performance. A spring-jack mechanism allows pressure mounting without permanent modifications, making it suitable for rentals, while the included mounting components also support a more permanent installation. Adhesive weather seals are included to help provide additional protection from the elements.
