Base rail 

This is the rail that rests on the string and beneath the balusters.

Closed or cut string staircase  

The sides that hold the treads and risers are known as the strings on a staircase. The borders of the stairs are disguised in a closed string staircase. The side profile of the stairs will be visible or may even overflow the string in a cut or open string staircase.
