We have a Ring Video Doorbell 4 and which was mounted on a corner plate.
The doorbell comes different screws originally, and in screw pack “C” there are 4 short screws to fix the doorbell to a corner plate.
We moved house a few weeks ago and have lost these 4 screws. Unfortunately, none of the Ring spare parts kits seem to contain these 4 screws (which, to repeat, are ONLY to attach the doorbell to a corner plate) and I wondered if anybody had any idea where we can buy some?
