Features

The B&D Control-A-Door 4 replacement worm gear kit will allow you to be able to engineer a DIY-able fix for when your sprocket breaks. A common reason behind the sprocket breaking is that the smaller cog on the dual sprocket was used, which places immense strain on the unit for the sake of a 1.5 second faster opening speed. This can cause either the shaft to break, or the gear to shred under pressure.
