Bottom Bracket Garage Door Bracket

You install this garage door bottom bracket at the very bottom of the last panel on your garage door. This bracket holds the final roller as well as the extension or torsion cable. This particular bottom bracet is compatible with most residential garage doors as well as most light commercial doors too. This is the most common of the garage door bottom braces available. There are a number of reasons why the bracket may need to be replaced, but the main reason is because the bracket and track rubs together and a groove rubs into the bracket. Eventually bends occur and the bracket is not as secure as it used to be. While you could have a professional change out the bracket, it is a simple do it yourself task, so why not do it yourself? All you need is a common screwdriver and a few minutes of your time. Check out our video below for more information.
