  • KR20 Sidewinder

  • Part No KR20
  • The YewdaleKestrel KR20 sidewinder roller blind incorporating Slipstream┬« Technology (patent pending) has a metal control chain as standard. White metal universal brackets are fitted to a white aluminium back bar for face, top or side fixing, and with 32mm, 40mm or 45mm grooved aluminium barrel, depending on blind size and fabric weight. The fabric is locked into a groove in the barrel, and features white plastic bottom bar as standard. The bottom bar is fabric covered at the front. This system uses magnetic wall-fix or top-fix brackets. This ensures that, under excess load, the back bar separates from the bracket leaving no remaining points of ligature.

O+M Guidance

It is an NHS Estates requirement that items suspended on load-release support systems should be maintained and load-tested in accordance with the manufacturer’s instructions on an annual basis. The YewdaleKestrel® system is maintenance free and its performance remains constant even after repeated use. It is a requirement, however, to carry out a physical inspection of YewdaleKestrel® fittings to identify any possible damage or evidence of tampering.

Safety Note

Sensitive electronic equipment may be damaged by proximity to a magnetic field and should not come within 150mm of the underside of the brackets. Any load-release device, by its nature, may cause damage when operated. Articles suspended from the YewdaleKestrel® magnetic anti-ligature system will come down when pulled.

YewdaleKestrel® products are designed as standalone products only. Care should be taken when assessing or arranging a room to ensure that YewdaleKestrel® products cannot be misused in conjunction with any other item, furniture or fixings in the room. It is the responsibility of the end user or client to ensure the product is suitable for the environment it is being installed in. YewdaleKestrel® products must be fitted by a qualified professional following the manufacturer’s instructions. Failure to do so could jeopardise the product’s effectiveness as an anti-ligature system.
