Detailed explanation

1. The manual roll-down blind uses 28mm or 38mm diameter aluminum alloy round tubes to achieve the lifting and lowering function of the fabric through the pull beads. 2. The system is equipped with built-in deceleration devices, which have anti-skid and self-locking functions. The pull beads have a small friction coefficient, which makes operation flexible, smooth, and easy, and is less prone to damage. 3. The heads and parts are made of high-quality imported engineering plastics, which are wear-resistant, anti-aging, and less prone to deformation, ensuring the strength and service life of the product. 4. The pull-string roll-up blinds are characterized by their simple and convenient installation, long service life, high strength, minimal environmental impact, and a minimalist, elegant, and fashionable appearance. Widely used in offices, schools, hospitals, and other venues.
