DESC: ''Heightened'' security for fearless climbers. The Fort Knox of safety gates! This 41''H metal gate is about a foot taller than standard gates, thwarting even relentless explorers. Is it sturdy enough for stair tops? You bet! One-touch operation. Expands to fit doorways 29''-38½''W (with 6'' extension included). For wider openings, add one 4'' extension (secures up to 42½''W) or one 24'' extension (secures up to 62½''W).
