Whitco Winder Lockable Chain - 5 Disc Finish-Gun-Metal-Grey Inspired by classic Victorian designThe Whitco 5 Disc Lockable Chain Winder is the go to solution for awning and casement windows the kind that crank open rather than slide. It replaces your existing winder while adding a proper key lock, giving you both smooth operation and genuine security in one unit. It's a particularly common upgrade in homes where the existing winders have aged, corroded or no longer lock properly. It also directly retrofits over older MK7 and MK8 Whitco chain
