This Hauck Safety Gate is designed for stairs and doors, with a width of 84 to 89 cm, making your home child-friendly. The gate is easy to install without drilling, using four adjusting screws to clamp it between door frames or stairs. It features a one-handed, double-sided opening mechanism, allowing you to lift the door and push the lock back in both directions. Additional extensions (9 cm or 21 cm) and a Y-spindle for stair railings are available separately. The self-adjusting baby mesh protector straightens as you tighten the screws, ensuring a secure and parallel fixation.
