Designed as an expandable 6-panel pet safety gate, this metal-framed barrier stretches from 34.5 to 154 in to enclose stairways, doorways, fireplaces, and play zones. The 270 degree rotating hinges let you shape it straight, L-shaped, U-shaped, or into a 43.3 x 41.33 x 29.13 in hexagonal playpen. An auto-close 16.5 x 28.5 in door stays open at 90 degrees for foot traffic and re-locks automatically. Reinforced metal panels with 10 extension tubes and mounting hardware deliver lasting strength for active homes with dogs and other pets.
