The Butterfly handle is a front-mounted fastener providing one lock point on a sliding sash. It is applied on the internai side of the sash and is compatible with virtually ail sliding profiles.
Butterfly has a snap-on fixing system: that is to say it closes automatically when the sash is brought up to the frame.
It is disengaged simply by pressing on the side of the hand grip.
Butterfly is supplied with two types of strikers in nylon for application on the frame according to requirements.
