Bottom brackets, standard and flag brackets, low-headroom brackets, wall and bearing brackets, roller door mounting brackets in domestic and industrial sizes, plus the pressings, screws and U-bolts that hold the whole assembly to the building.
Bottom brackets are the highest-stress part on a sectional door β they anchor the lifting cable at the bottom of the door, which means they carry the full spring load. They are the one bracket that must never be unbolted while the door is under tension.
Bearing brackets carry the torsion shaft. A centre bearing bracket supports the middle of a wide door and end bearing brackets sit at each side; a dry or failed bearing announces itself as a squeal that rises with door speed.
Roller door mounting brackets come in domestic and industrial weights. The industrial version is heavier gauge for larger barrels and commercial door weights β worth matching properly, because an undersized bracket on a heavy door will eventually pull.
Angle and plate pressings are the mounting hardware for hanging motors and tracks off a ceiling. Note that longer pressings are pick-up only; they do not post.
Because the lifting cable anchors to it, the bottom bracket holds the full spring tension. Unbolting one on a closed door releases that load suddenly and is one of the most dangerous things you can do to a garage door.
Usually a dry or worn bearing in the centre or end bearing bracket. It typically gets louder as the door speeds up and is worth attending to before the shaft starts to wear.
Only if the door and barrel are commercial weight. For a standard domestic roller door the regular mounting brackets are correct; oversizing gains nothing.
