4840 Roller Blind System is a wall, ceiling or recessed mounted, endless chain operated roller blind designed for very heavy duty contract applications, for left or right hand operation. It is made to measure and supplied ready assembled.

Headrail support tubes options:

  • Ref 4901: Dimensions – 80 mm diameter; maximum 4000 mm wide.
  • Ref 4957: Dimensions – 110 mm diameter; for systems over 4000 mm wide.

For systems under 4000 mm wide, on-site adjustment of the headrail is available to prevent rolling-off caused by minor fabric problems. An automatic end-of-travel brake is fitted and optional side guide wires are available as an option.

The blinds incorporate an adjustable stainless steel bracket set with vertical adjustment facility. Pre-fitted hook-on stainless steel plates take the weight of the blind whilst the fitters carry out final positioning of the brackets. The latter are each adjustable sideways by up to 18 mm. The blind is then conventionally fitted from below (especially important in a blind box situation).
