does it matter?
A neighbor recommended retract-a-gate but these are expensive and I think I want a pressure-mounted gate.
We have this one http://www.walmart.com/catalog/product.do?product_id=10741056&sourceid=1500000000000003260550&ci_src=14110944&ci_sku=10741056
My sister and BIL got it for their dog but he stopped needing it just before L needed some boundaries. It works great, it is a tension mount, and you do have a locking mechanism to help little hands stay out.
