I lost the parts to my KidCo fireplace baby gate and made my own. These wall plate is designed to be screwed into the wall to securely attach the baby gate. The PivotPin is designed to slot into the two gate pieces to allow them to rotate with pressure greater than that of a toddler while still holding the gate pieces together.
Note on assembly: It's best to position the gate where you want it and then insert the PivotPin. It will allow it to pivot with enough force but the more you try to bend the gate with the PivotPin in then the more wear it will accumulate. In my experience, it applies more resistance to bending the gate then the default parts so it should resist a kid bending the gate by default.
