Box Newel Post:
An oversized square newel that is usually hollow and is used in a post-to-post balustrade system.
Bullnose Starting Step or Tread:
A starting tread that has one or both ends rounded to a semi-circle and projects beyond the face of the stair stringer.
The part of the fitting that accepts the newel post; used in conjunction with a pin top newel in an over-the-post balustrade system.
False Tread Caps:
A piece attached to the end of a rough tread to simulate solid wood treads, usually with a carpet runner down the steps.
A thin strip that is usually flat on one side and fits into the plow of a piece of handrail.
A fitting that is used in the transition of a handrail to a landing or balcony; compensates for the change in the rise of the stair and may make a change in direction.
The top rail used in a balustrade system; provides a gripping surface for added support.
A part used in a balustrade to compensate for a change in direction. Handrail fittings can be used in both post-to-post and over-the-post balustrade systems.
The vertical distance between the upper surface of the top rail and the leading edge of the tread or the finished floor.
A horizontal platform at the end of a flight or between two flights of stairs, usually used to make a change in direction.
A post used on an intermediate or second floor (balcony); generally used where there is a change in direction or where a rake rail meets a level rail.
A part used as the tread on a landing that forms a level surface with the finished floor on the second floor (balcony). Also used as a level surface to attach balusters.
A large vertical column or post to which the handrail is attached. Newels provide structural support for the balustrade.
The part of a tread that extends beyond the riser; can also extend beyond the fascia on a balcony.
A stair that is open on one or both sides, thus allowing riser and treads to be visible.
A convex rail fitting used to transition from a rake rail to a level rail.
A balustrade system in which the handrail runs over the post and is continuous (uninterrupted).
A recessed area in the bottom of a handrail or in the top of a shoe rail; the square top and bottom of a baluster is designed to fit into the plow.
A balustrade system in which the handrail runs between the newel post, with the top of the post projecting above the rail.
A rail fitting that makes a 90 degree or right angle turn.
Quarter Turn Cap:
A quarter turn cap is made to mount on top of a pin top newel in an over-the-post rail system.
The angle or slope of a stairway that is determined by the rise and run.
Rail section that runs parallel to the slope of the stairs.
The vertical distance from one tread in a stair to the next.
The vertical face of a stair step.
A decorative trim part used where railing runs directly into a wall; provides a surface for anchoring.
The horizontal width of a tread between the faces of adjacent risers.
The molding on top of a stair stringer upon which the balusters rest.

The fitting at the bottom of a stair.
The newel post used at the beginning of the balustrade railing.
The first tread and riser of a staircase.
A rail fitting used to make a break in a straight rail section to allow attachment of a newel.

The concave rail fitting that is used to make the transition from a rake rail to the horizontal piece of a gooseneck fitting or starting fitting.
The spiral starting of the handrail at the foot of a staircase.
A tread that is wide at one end and narrow at the other and is used for carrying stairs around curves or angles, as on a spiral staircase.
