How it works

The parts of a stair railing and the parts of a deck railing, in two drawings. The stair railing is the kind whose handrail runs over its posts, so it shows the fittings: volute, gooseneck and rosette.

Parts of a staircase railing, from the first step up

The handrail starts in a volute over the starting newel, climbs over the balusters, and turns up at the gooseneck to reach the landing newel. Along the landing the balusters stand in a shoe rail, with a fillet between each pair, and the rail ends at a rosette on the wall.

A deck railing

Two rail posts carry a top rail and a bottom rail, and the balusters are fastened between the two. A cap rail lies flat on top, and a post cap covers the top of each post.

  • Shopping for the parts of a handrail? Volutes and goosenecks are sold as fittings, separate from the straight rail.
  • Balustrade is the name for the whole system of handrail and balusters.

Questions and answers

What are the vertical parts of a railing called?

Balusters. They are the slim uprights that hold up the handrail, and they are also called spindles; deck builders sometimes say pickets. The thicker posts at the ends are newels on a staircase and rail posts on a deck.

What are the parts of a banister?

Banister can mean the handrail alone or the handrail with its balusters. The whole system of rail and balusters is a balustrade, and the large posts that anchor it are newels.

What is the curled end of a handrail called?

A volute. The handrail curves inward like a spiral and sits over the starting newel on the first step. A turnout is a simpler fitting that swings the rail to one side without the full spiral.

What is a gooseneck on a stair railing?

The upright piece of handrail at the top of a flight. It joins the sloping rail to the higher, level rail on the landing or balcony.
