Fallshaw 'Natural Directional Lock' (NDL) castors are designed specifically to resolve hard-to-steer trolleys and eradicate confusing directional lock systems.
The NDL caster intuitively locks the castor from swivelling when travelling in a forward motion. A simple motion (reversing by a few millimetres – something that people do intuitively) then releases the swivel lock allowing the trolley to be fully manoeuvered in any direction. There is no other similar product on the market.
The castor design is patented (Patent number: AU2005237657).
