Meh . . , bought to keep our adventurous new kitty out of the food cabinets in our rented townhome. Because of the distance between the knobs, they don’t tighten up enough to be cat-proof, but with the addition of a few thick rubber bands, they help do the trick. Will seek a more effective solution. Luckily they are inexpensive so not a big deal.
