The actual way to install this product is to remove the plastic latch from the cross bar, simply by moving the latch to the right. Next, make sure the rubber stoppers are firmly pressed against the surface(s) you are trying to block, such as the frame of a door. Next, without moving the gate from it's maximum stretch position, lift the cross bar so that the metal latch locks in place, then lower the cross bar and move the plastic latch back into place on the cross bar. If done correctly, the gate will not move from gently pulling and pushing it, and the cross bar will only move under pressure. I personally didn't like this product until I figured it out, mainly since the only instructions for the gate I have are in Portuguese on the official website.
