Product Features

Not only aesthetically pleasing but also combines ventilation, mosquito protection, and anti-theft functions. The product design utilizes indoor-outdoor air pressure and temperature differences to create convection. Even when the door is closed, it maintains ventilation while retaining anti-theft functionality, with ventilation capacity up to 1/2 of the total door area. U-shaped steel cable transmission reduces opening force and noise, extending product lifespan. Inner frame structure uses embedded design for robust construction and deformation resistance.
