Eight connected panels form an octagon-shaped safety fence that expands from 34.5-154 in to block wide openings, section off a room, or create a contained area for pets or children ages 1-3. Each 24.6 x 29.13 in panel joins with 270-degree rotatable joints, so you can angle the barrier along walls or around fireplaces and windows. The metal frame with nylon, PP and ABS components stands 29.13-in tall to help limit climbing or jumping. A built-in gate with a 16.5 x 28.5 in opening uses a double locking system to reduce accidental escapes and folds to 29.13 x 26 x 8 in for storage.
