This is a 45 degree mounting bracket and a 1/4 inch spacer plate for the Nest Hello doorbell. The mounting bracket is made in two parts. The flat base that is mounted on the wall or door frame, with holes for screws and cables.
The other part is the 45 degree part which has guides but no holes for mounting screws. There is also a hole for the cables which lines up with the base and the metal clamp.
The components must be assembled together with adhesive and the cable installation can be easier if the metal clamp is attached to the 45 degree adapter before assembly with the base.
