Stair Parts & Custom Stair Components
Mason’s Mill & Lumber supplies custom stair parts and components for residential and commercial projects where detail, consistency, and fit matter.
From treads and risers to handrails, balusters, and newel posts, our stair parts are milled to specification using carefully selected hardwoods and proven production methods.
Stair Parts Custom Made in Mill 3
Balusters and Balustrade
Balusters are the vertical posts supporting the railing, working with the handrail to form the balustrade system. While three balusters per foot is standard, tighter spacing can add an elegant touch to your design.
Handrails
Handrails provide support and safety, resting horizontally or at an angle above the balusters. Smooth transitions in handrails are achieved using fittings like volutes, turnouts, or goosenecks, blending practicality with style.
Newel Posts
Newel posts are the larger vertical supports anchoring the balustrade system. Placed at key points—like the base, top, and turns of a staircase—they provide both structural support and a bold design element.
Treads and Risers
Treads are the horizontal steps you walk on, while risers are the vertical supports beneath them. For a sleek, modern look, risers can be omitted, creating an open tread design.
Nosing
The nosing is the edge of the tread or landing tread that extends beyond the riser, offering more walking surface and a polished appearance.
Fittings and Moldings
Fittings such as upeasings and goosenecks create smooth transitions when the handrail changes height or direction. Decorative moldings, like cove molding, enhance the design by covering joints between treads and risers.

Solid Hardwood Tambour Panels
Tambour panels are solid hardwood slat panels mounted on a flexible backing, which lets a single panel wrap curves, columns, and outside corners that rigid paneling cannot reach. White River mills its tambour in Fayetteville, Arkansas from North American hardwoods and ships it unfinished, ready for any paint or stain. It is the most specified architectural wall panel in the White River catalog - used on kitchen island waterfalls, curved reception desks, cabinetry faces, and full feature walls.
Companion product: Solid Wood Paneling (SWP) is tongue-and-groove hardwood paneling, 11/16 in. thick, and every SWP profile corresponds directly to a tambour style. Run SWP on the flat walls and tambour on the curves in the same room - same profile, same species, same finish, no visible transition.
