Some doorways are irregularly shaped and does not allow for a traditional pet gate to reach both sides. This Richel Freestanding Pet Gate is a great solution because this pet gate stands up on its own without having to clamp or use any tools. It is also a very luxurious hardwood finish and even folds up completely flat for storage and transport. Another great feature is that this gate is a little shorter - specially designed for smaller dogs so you can walk over it easily. There is a larger version available. $120. BUY.
