This stainless steel protector wraps around the eject hole and protects the rear edge of the drop target slot.
We ship these with the screw tabs unbent. This means that the installation can be done without removing the drop targets. If you need the screw tabs for an installation, bend them carefully with wide-nosed pliers to an angle just a little greater than 90 degrees.
