The clockwork mechanism is released by a thin rod that passes through the door to a bell push button on the outside. This rod is adjustable for different door thicknesses, but where doors are particularly thick, we can supply longer rods.
Wind it up.
When fully wound, the bell will ring for approximately 75 seconds, and since a typical visitor will press the bell push for between 2 and 3 seconds, the mechanism will support up to 30 rings.
Customise your windup doorbell with different button styles and material finishes.
