The installation manual is very brief and unclear. We were not able to install it at the bottom of our stairs. Screw holes are designed so they are not secure with the screws attached to the knobs. They are seemingly stripped, so any time we tighten/adjust the knobs the right side the left slides out of its place and vice versa. Therefore, the opening of the gate will not narrow enough to activate the magnetic feature. I would return this product, but the store I purchased from went out of business.
