What Are Garage Door Bottom Bracket
You’ll usually spot garage door bottom brackets right at the bottom corners of your sectional garage door. They’re pretty important because they’re where the lift cables get attached. As the door opens and closes, the bottom brackets transfer the full weight of the door to the cable and spring system, making them one of the highest-load components in the entire door assembly.
All that constant strain? Bottom brackets need to be shaped just right, held on tight, and built tough enough to keep the cables from slipping around.Good bottom brackets are key for garage doors, whether for your home or a business. They make sure the door lifts evenly, glides smoothly, and stays safe for a long time.If you need help picking out the right bottom bracket or ensuring it fits your system, just get in touch with Gemax. We can give you technical support and product assistance.
