'Natural directional lock' (NDL) castors make steering easyFallshaw '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 manoeuvred in any direction. There is no other similar product on the market. The castor design is patented (Patent number: AU2005237657). |
Benefit for customers: enhanced user-experience | |||||
|---|---|---|---|---|---|---|
Sometimes customers want to travel in a straight line(without having to 'crab-steer' or battle with the trolley). 4 swivel castors make this difficult (particularly when the trolley is full and on a slope in the car park). 
Sometimes customers want to travel sideways(particularly when moving aside for passing customers in narrow aisles). 2 fixed rear castors (which aide steering and are widely used in the USA and NZ) make this impossible. 
NDL castors enable both intuitively – without requiring instruction |

| How do they work? | ||||||
From a user-perspective none of this matters! The easy steer castor is intuitive to use - customers 'feel' how to use it without being taught. They naturally figure it out within about 30 seconds. And from then on the trolley is 'magically' easy to steer and push. |
