Abstract
A between-the-glass slatted blind operator includes an enclosure having a housing and a bottom wall. All of the gears are contained in the housing and the bottom wall is placed over the top of the gears when the operator is being assembled and being locked in place by inwardly deflected tabs on the housing side walls. The bottom wall has upwardly extending gear supports which oppose the gear supports in the housing. The bottom wall is unexposed to view when the operator is in its position of use.
