16-gauge junior adjustable top fixture with a black powder coat finish. This bracket goes at the very top of the door's top section and holds the top roller that guides the panel into the track. it is adjustable so you can tweak the alignment where the door meets the header and weatherstrip. When your top bracket is beat up, bent, or wallowed out, the door will rub the header or leave a gap at the top. This product is the black coated version. Check that the bolt pattern matches your existing hardware and that the roller stem fits the bracket slot.
