Several of the earlier door lock plate keeps included a small grub screw bolt and nut that allowed the keep to be adjusted so that the opening sash could be dragged into the outside frame as needed. This upvc door latch keep bolt becomes loose over time as the door is opened and closed, and the nut goes down inside the upvc system, and the small bolt falls out, never to be seen again. These bolts were found specifically for such scenarios in order to restore the entire length of the keep plate.
