ABSTRACT:
A ladder for horizontal blinds is provided having a drawstring pre-threaded through a plurality of loops on at least a first leg. A second drawstring pre-threaded through a plurality of loops on a second leg may also be provided. When assembling horizontal blinds using the ladder, a pull cord is easily threaded through the loops by securing it to the drawstring and pulling the drawstring/pull cord junction through each of the loops. Manufacturing costs associated with assembling horizontal blinds are thus reduced by eliminating the labor-intensive step of individually hand threading a pull cord through each loop.
