I bought this position and lock gate to keep my puppy from doing her business in a certain room. I followed the instructions on the packaging, "Push tab on gate latch and slide gate latch off the locking bar. Lift up on the locking bar. The gate latch doesn't move. I have strong hands yet no matter how much pressure I put on it it doesn't move and I don't want to use tools, and the packaging clearly says, "No tools required". I've squeezed it so hard with my hand that the latch is turning white, meaning it's going to break if I continue.
I don't recommend this to anyone.
