There is a pair of brackets at the top inside corners of most overhead residential doors. They can work loose over time. Their function is to hold the top roller carrying fixture in
place.
On the bottom of your door is another pair of brackets.
They can become damaged with time as well.
If the door is left open frequently, they may be exposed to the elements and become rusted.
Their purpose is to support the bottom roller and help to hold the cables in place.
There are specialty brackets for doors with low headroom. They are durable and long- lasting but could need to be replaced if the door is getting older. In additions to the brackets, there are bearing plates that can work loose or suffer from wear and tear. Most brackets (other than the center bracket) and bearing plates are sold in pairs by garage door specialists. Home improvement stores sometimes sell a single bracket or plate. Replacing only one bracket is unwise. If one has become cracked or broken, the other one is likely to go soon.
The brackets are relatively inexpensive. If they fail the door could be irreparably
damaged. Remember that this door is one of the things that keep your house secure. Always look to the real experts for advice, before listening to a self-trained handyman.
