The pleated insect screen (mosquito net) without threshold is the ideal mosquito system for structures with large openings. A feature of this mosquito net is the absence of a threshold. However, there is a 3 mm high guide bar. Pleated anti-mosquito systems allow installation on all types of windows and doors.
This anti-mosquito system is especially popular with villa owners in Bali as the absence of a threshold makes it a bit more convenient.
The rest of the advantages of this system are the same as the net with the threshold. This is a large size of the protected opening (up to 3×6 m), the absence of complexed wearing-off equipment (springs, levers, etc.) and ease of use due to a folding accordion mesh.
