ABSTRACT:
An indexed limit stop for mounting on the headrail of a covering for architectural openings is easily connected to the headrail in overlying relationship with shade material wrapped on a roller in the headrail and has two elements that are pivotally interconnected and movable between selected fixed positions. The second element includes an abutment stop for engagement with the bottom rail of the shade material when the covering is fully retracted and can be positioned such that the abutment stop is spaced from the outer wrap of shade material to avoid damage to the shade material while being desirably positioned for intercepting movement of the bottom rail to limit retracting movement of the roller.
