Stair Trim Components

Stairs

• Knowing correct stair terminology helps you understand how stair trim components fit into a stairway. The vertical height of a stairway is called "rise," and its horizontal footprint is called "run." The horizontal surface of each step is known as the "tread," and the vertical pieces that fill in the space between treads are known as "risers." The edge of each tread that overhangs the riser is called "nosing." These parts comprise the components of a stairway.

Newel

• The newel is the vertical post that starts the stair trim structure at the bottom of the staircase. The newel serves to anchor the handrail. It is often the largest, sturdiest and most substantial piece of trim on the entire staircase. A "newel cap" is an optional decorative trim piece that tops the newel, much like a finial on a lamp. Interior decorators use the newel post to tie the stairway

Handrail

• The handrail helps you, your family and your guests use your stairway safely. A handrail should be wide enough to provide support but not so wide that a person cannot easily grasp it to prevent a fall down the stairs. The handrail should be smooth and polished so that it does not splinter or snag skin or fabric. Handrails are often made of wood that has been stained or painted to match the rest of the staircase trim.

Balusters

• Balusters are the trim that fills the space between the handrail and the tread. Balusters can help prevent a small child -- or anyone who has lost her balance -- from falling sideways off the stairway. A traditional stairway uses round wood balusters, while modern stairways use taut steel cables installed parallel to the railing in lieu of balusters. Stairways in homes built in the Tuscan or Spanish style often feature ornate, wrought iron balusters that complement the architecture of the home.
