Fits: Adapt to door frames about 188cm to 248.9cm high and 90.2cm to 95.6cm wide. Please measure it before you buy it. Effective for cats: Up to 188cm high gate can sufficiently stop jumper cats. Less than 3.6cm narrow bar spacing stops kittens from squeezing through. Two latches with secure locks could be clipped to different heights on the door; no smart kitties are able to figure all this out. Three support pillars: The second-generation upgrade has increased from two pillars to three support pillars and widened the support brace to solve the problem of being loose and easy to fall off. Greatly increase the stability. One-hand walkthrough: Double-acting doors swing in both directions. Latches are easy enough to operate with one hand on both sides. Hold & auto closed: Doors can stay opened when opened to 90 degrees, allowing going in and out freely. When opened less than 90 degrees, both doors swing back closed automatically to avoid careless moments. No drilling assembly: Pressure-mounted structure could tightly hold on to the door frame. Adjustable support poles could be flexibly lowered or raised to fit different high door frames. Blue Elephant Size: 250cm (222.8cm) H x 128.3cm W x 2.8cm D
