BUILT-IN CHAIN OPERATED FLYSCREEN 50 MM WITH CLIC-CLAK®
SIGMA is a chain operated flyscreen made of fibreglass mesh, fitted with the unique clic-clak® system, an International Bettio Patent that allows opening and closing the flyscreen by simply pulling the chain. The perfect combination between the chain drive system and the advantages of the spring system makes it an ideal product, characterised by smooth operation and perfectly stretched mesh at any time. Sigma is a built-in flyscreen that vanishes completely in the window frame. For installation, use the adjusting profiles already included with the product. Standard control is on the right. The standard bracket and support spring make it easy to install on the construction site or directly on the window frame during manufacture.
