These stylish channel outdoor curtains are aesthetically pleasing as the powder coated aluminium channels at the sides of the curtain  cover the edges of the mesh/PVC.  Gearbox channels are operated using a winder handle.  The spring loaded option however is operated by simply lifting the curtain up and down using the bottom bar once the side release mechanism has been activated.  Both options can be stopped at the required height and made to be motorised if required.
