Threshold Meaning
When discussing vertical platform lifts, the word ‘threshold’ is used to describe the area directly below a lift door or gate. In the home, a door-threshold will be a piece of wood or stone that is referred to as a doorsill and forms a small step designed to halt the ingress of water or drafts. However, in the Platform Lift industry, the word threshold is used much more generally, to simply describe the general area where a vertical face (wall) meets a horizontal plain (floor).
