Once upon a time, opening a fly screen required concentration and attention. If the handle accidentally slipped out of your hand, the rewinding spring in the box would “retract” the screen abruptly, creating loud and annoying noise.
BAZAR fly screens incorporate a mechanism that slows down the fly screen opening action to eliminate this possibility. Once the handle has been unhooked, the upward rewinding (for vertical fly screens) or sideways rewinding (for horizontal fly screens) takes place automatically in a slow and controlled manner.
