Rackarms are one of the most appropriate blind types for rooflights and sharply sloping glazing, particularly suited to conservatory roofs. These non-retractable blind systems were originally designed over 30 years ago for use on rooflights in museums and art galleries as a cost effective and maintenance free solution to controlling light. The timber or aluminium slats are rigidly supported by aluminum racks via articulated arms, eliminating the problem of sagging which can occur with fabric roof blinds.

Gear operated -A gearbox is fitted to the tilt shaft, and is turned by a detachable crank rod, this is suitable foruse on large and high level blinds.

Motorised Operation -A tubular motor drives a gearbox that is connected to the tilt shaft. Useful for blinds where access is difficult and group contrtol is required. Another useful feature with motorised operation is the option for automatic control, solar sensors can be added to open and close louvres at selectred external light levels. A timer control can be also be incorporated to provide automated control of blinds at chosen times.
