This safety gate is being used to span an area between a kitchen counter island and a wall. There is 41.5 inches between the two and I worried I would need an extension. But it fits perfectly, is sturdy, and keeps my dogs away from me while I am working. Although just 12 and 7 lbs each, these pups were able to Houdini through just about every other gate I had tried in this strange area. But not this one! Very well-pleased.
