Adding Carriage-Style Garage Doors

Two steel cables transfer the springs' tension to the door. We hook one end of each cable to a bracket at the bottom corner of the door and pull it up to a sheave attached to the upper track. The cable then loops around the sheave on the spring and hooks to the brackets anchoring the curved track sections. We remove the C-clamps. When balanced, a door will need the same force to slide it up and down.
