Ventlock for PVCu White and Chrome cover The high level of coverage that security issues are receiving in the media, for example Secured by Design in the window trade press, is proof that security remains a leading issue. This is why Mighton, the premium sash window hardware specialist, has launched its new PVC-U Ventlock to help customers offer the best possible security to homeowners. Customer feedback has shown that homeowners are buying windows not just for the style or finish but are considering security when making their purchase. Ventlock is discretely installed into the top sash window, six inches above the meeting rail. When deployed it prevents the bottom window from being opened further. Ventlock is quick and simple to install: Drill hole Insert Ventlock Drill rivet holes POP rivet Ventlock to the sash Conceal rivets with self adhesive trims As with all of Mighton's products, Ventlock is being tested to all relevant standards for window.
