These fittings can be universally applied to any European-style casement system that has a frame with a minimum height of 40 mm on the interior side. Within the Innaltech systems, these fittings are standard applications in the Alfil 45 (PF43), Practic 45 RPT (PT45), and Practic 54 RPT (PT54) series.
Woorbel, the manufacturing and accessory development division of Grifell Pons SL, offers specific fittings for the fabrication of European-style folding systems. These can also be universally applied to any European casement system with an interior frame height of at least 40 mm.
The system is suspended from the top track by trolleys with four wheels each, equipped with 6 mm stainless steel needle bearings. These trolleys glide smoothly inside a double raceway track that guarantees complete absence of wobbling. The bottom track can be surface-mounted or recessed. The recessed option, available in the Practic 54 RPT, is compatible with the use of a threshold, which is an optimal application as it combines the practicality of the folding system, its high watertightness, and the absence of lower obstacles on the floor.
It is a versatile system, easy to install and providing excellent watertightness, ideal for open spaces that alternate between different uses depending on the season or prevailing weather conditions. Perfect for terraces, porches, gardens, pools, etc. Without a doubt, the folding system is a closure system that supports many applications and enables spaces with otherwise incompatible uses.
