Abstract
A fenestration control includes a single loop cord in association with guide members and a drive pulley built into a generally channel-shaped framework and is specifically designed for use with pleated or cell-type shades. The entire shade assembly is capable of being removably installed within window openings and the like and may be operated manually, or by single or dual motor drives depending upon the size and load requirements of the shade.
