The Markilux 710 and 810 are identical save the shape of the cassettes being either round or square profiles. Stainless-steel cables are affixed to the wall parallel to the drop of the blind down which the lead bar runs. Gravity reliant, this awning will not retain tautness as there is no additional tension. Either manually operated by means of a universally jointed coupling and bayonet fitting or electrically operated by a tubular motor housed in the cassette. The Markilux 750 and 850 share the same specification other than the guides are stainless steel rods, not cables.
