Ideal for using Master handles on both the sliding systems as well as on tilt and turn and casement systems.Shark unidirectional mechanism and Bing bi-directional mechanism were designed to further simplify and accelerate the work of every window maker. Shark is a unidirectional mechanism with a reduced size that snaps into place on the profile and is completed by two simple self-drilling screws, in order to guarantee resistance over time. Furthermore, this system also facilitates transporting the sashes, since the handle can be installed directly on site.On the WEEN tilt and turn, with a capacity of up to 160 kg, it is possible to associate both the version with the anti-false maneuver (with lever made of friction-proof and scratch-proof material, in order to prevent damage to the sash while handled) as well as the version without, in combination to the WEEN kit with upper anti-false maneuver mechanism.Bing, however, is the new bidirectional mechanism, designated for both casement systems that open internally, as well for those that open externally, adjustable from 15 to 35 mm, thanks to a new spring system with reference guides and the returned output mechanism of the handle movement (patented), which can be installed also on larger profiles or insulated ones. An outer casing covers the sliding levers of the movement system, ensuring the safety of the accessory, as well as a better aesthetic quality for the frame.Available on the market since November 2014, both for R40 profiles, as well as for Camera Europea, Shark and Bing are Masters’ solutions allowing all of its handles, from the Italia line to the Comfort line (also in the new version with lock), to be applied to all types of opening mechanisms.
