Mommy's Helper Safe-Lok Cabinet and Drawer Lock Ouch! And your child starts crying. We all know children like to explore places, but when a little finger gets pinched in a drawer there's trouble. You can now prevent this with the Safe-Lok Cabinet and Drawer Lock by Mommy's Helper. This patented cabinet and drawer lock prevents children from getting into places that they shouldn't - such as the silverware/knives drawer - and keeps their fingers from getting smashed. A patented design allows the cabinet or drawer to open 1 inch and locks it there, so that little hands can't get slammed in between. Easy to install and very practical.
