Abstract
A window opening control devices in the nature of a modified vent stop includes a housing having a peripheral flange defining an opening and a body depending from the peripheral flange and further includes a butterfly shaped stop block mounted within the body of the housing for rocking motion about a generally centrally located pivot point between an open position, wherein a first wing of the stop block extends beyond the housing flange, and a closed position wherein the first wing is retracted into the housing. Movement of the stop block between the open and closed positions is effected by pressing on either the first wing of the butterfly shaped stop block or a second wing, and is preferably accomplished without the use of springs or other biasing assistance. The stop block is preferably provided with a pair of ridge projections that cooperate with spring legs located on the interior of the housing to form a detent to maintain the stop block in the closed position.
