TL;DR
A winding cone is the cast fitting clamped into the free end of a garage door torsion spring, drilled with sockets where steel winding bars seat so a technician can add or release the spring's stored turns. Its partner cone at the other end anchors to the spring bracket, and set screws lock the winding end to the shaft once tension is correct, roughly one turn per foot of door height as a starting point.
What it means
A winding cone is the cast fitting clamped into the free end of a garage door torsion spring, drilled with sockets where steel winding bars seat so a technician can add or release the spring's stored turns. Its partner cone at the other end anchors to the spring bracket, and set screws lock the winding end to the shaft once tension is correct, roughly one turn per foot of door height as a starting point. Cones are wound-direction specific, red for right wind and black for left by convention, and improvised winding tools like screwdrivers in place of proper bars cause some of the trade's worst injuries.
