An adjustable depth electrical wall mount ring can include a base ring and a finishing ring. The base ring can be configured to be attached to a junction box. The finishing ring can be configured to be adjusted relative to a ring portion of the base ring to extend away from the junction box through a wall layer. Adjusting the finishing ring can cause one or more outward extensions on the finishing ring to bear on an exterior surface of a wall layer and thereby urge the junction box towards the wall layer.
