• ANDO™ manual chain winders come in a large range of standard and special powder coat finishes.
• The corrosion resisting stainless steel chain and Polesium™ winder base protect not only the winder but also the window sash and sill. If a winder should corrode the window will almost certainly be damaged.
• Chain winder can be key locked. 
• Chain winder available control knob can be folded down.
• The length of the chain can be reduced on heavy sashes. This reduces the chance of damaging the projecting chain under high wind loads when sash is in the open position.
• Winder fixed to reinforced (thickened) sections on sash and frame to ensure fixing screws don't come loose.
