For use with constant force balance systems, the Jamma Lamma is a jamb pocket-mounted component that holds either a vent stop or window opening control device. The stop or WOCD is first snapped into the unit. Then, the unit is inserted into the jamb pocket, while the tension bow that holds it in position is adjusted and screwed into the desired position. From Lawrence Industries, the component allows for normal sash tilting and can be installed at the factory or in the field as an aftermarket product. The Jamma Lamma can be used to add a vent stop on a single-hung window, when internal components such as foam or reinforcements prevent the insertion of a normal vent stop. The unit can also be used to add additional vent stops for security.
