The design allows for relatively easy removal and installation, offering convenience in maintenance and seasonal adjustments. These screens are often found in older window models, though variations are still manufactured.
The significance of this screen type lies in its functionality and adaptability. Its relatively simple design often translates to a cost-effective solution for maintaining insect protection.
