B&D Worm Gear Kit Features

The B&D Control-A-Door 4 drive gear and worm kit will allow you to be able to engineer a DIY-able fix for when your white drive cog breaks. A common reason behind the gear 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. A complete installation guide comes with this kit, which will help you replace ytour old, broken garage door opener part. You will require some basic tools, such as a ladder, screwdriver, socket wrench and assorted sockets.
