Kappa is a retractable flyscreen with magnetic lock system, made of fibreglass mesh without PVC strip and pins. Its overall dimensions are very small. The double door version is fitted with a special mechanism that allows you to open and close the bolts locking one of the leaves without having to bend down. For installation, use the adjusting profiles already included with the product. The bracket and the support spring make it easy to install on the construction site or directly on the door frame during manufacture.
