Stylish and strong, lockable cranked window handle for aluminium and uPVC espagnolette windows. Manufactured by industry leader Yale, and supplied with a 10-year mechanical and surface guarantee. Offset handles are available for use with left or right hand and are designed to provide more hand clearance when opening. They are made from tough die-cast zinc, with a durable powder-coated or plated finish to offer high corrosion resistance, impact strength and protection against abrasion. Espag handles feature a 7mm metal spindle that is fixed to the lever and runs through the handle backplate to fit into a lock mechanism within the sash. Turning the lever rotates the spindle and triggers the mechanism, which in turn locks or unlocks the window. The Yale Quartus Espag handles are also available as inline straight versions, which can be used on left, right or top opening windows.
