This box helps protect your little one's fingers even without the lid. The box makes it hard to touch the metal plug if the cord gets pulled. The lid for the box fits tight and fits the diameter of a power strip cord to help hold it tight on the wall. Squeeze the sides of the box to remove lid.
Disclaimer: This does not replace common sense or good parenting. Before you install the box turn the power off at the breaker. Don't come screaming at me when you jam the screwdriver in the outlet. Remove the faceplate screw. Center the box over the screw hole and use the screw to secure the box to the faceplate. I'm sure if it gets hit hard enough the box will probably break being that it is only held on by one screw. This is also no guarantee that your kid is safe but every little bit helps.
