Abstract
A window covering for a fenestration product includes a top rail, a bottom rail, and a shade extending between the top rail and the bottom rail. A shade mechanism includes a rotatable lift shaft, a lift spool having a cylinder operably connected to the top rail for raising and lowering the top rail, and a resilient member operably connected between the lift shaft and the lift spool. The resilient member allows the lift shaft to over-rotate with respect to the lift spool.
