You had an upgraded steel bearing. Also, the painted red screws are intended for the bottom bracket. This is where the cables attach to. They are red to warn you not to remove the bottom bracket while the springs are holding tension. This can cause injury and at the least scare the .... out of you. Very nice job on the installation. Clopay makes a very good product, just always be careful with the spring tension!

Help we don't have the v-shape top hinge. It's flat.
