OKNOPLUS equips all their windows with original, brand name fittings manufactured by a German company called WINKHAUS. Two kinds of fittings are installed depending on customers needs: turn only and tilt-turn fittings, both characterized by easy use and horizontal and vertical adjustment, as well as easy adjustment of the amount of force applied to press the sash down, e.g. tightening of the window for the winter season can be done manually by changing the position of the regulating rollers.
Fittings are small components that could be compared to Lego blocks that are joined in line at variable combinations. A fitting combination that is too simplified even if made by the best manufacturer will not ensure correct operation, sealing strength and safety.
