This part is to replace the brackets that come with a dog/child gate that I purchased. The one I purchased is called Regalo 192-Inch Super Wide Gate and Play Yard, White.

This brackets are designed to easily remove and replace the gate. I used this to remove our gate that prevented the dogs from going into the kitchen when we had guests or moving large objects between the kitchen/dining area to the other side.

The holes are designed for a #6 x 1in flathead screw and use the appropriate drywall anchors.
