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.

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.

Vertical Grain Pine — Cutek Extreme Clear Finish
Vertical Grain (VG) Pine is a premium cut of pine milled specifically so that the growth rings run perpendicular to the face of the board — typically at 60° to 90° to the surface. This "quartersawn" or "rift-sawn" orientation produces a board with a tight, straight, pinstripe-like grain pattern that is dramatically more stable and refined than standard flat-sawn (plain-sawn) pine. Because the growth rings are oriented vertically, VG boards resist the cupping, twisting, and cathedral-pattern grain shifts that flat-sawn lumber is prone to, and they wear more evenly over time — which is why vertical grain has been the traditional choice for high-end architectural applications like porch flooring, exterior siding, boat decks, and fine millwork.
The visual character of VG Pine is one of its biggest selling points: consistent, linear grain lines with minimal figure or knots, producing a clean, understated appearance that reads as more formal and architectural than character-grade pine. This makes it particularly well-suited to applications where the wood is a design feature rather than a background material — traditional porch ceilings, Craftsman and coastal-style siding, wainscoting, and interior paneling.
Each board is finished with Cutek Extreme Clear, a penetrating oil engineered to stabilize exterior wood from the inside out. Rather than forming a surface film like paint or varnish, Cutek carries its oils deep into the wood fibers, where they work continuously to slow moisture movement — the primary driver of cupping, checking, and end-splitting. This is especially valuable for pine, which is more naturally susceptible to moisture-related movement than denser hardwoods; Cutek's stabilizing action significantly extends the board's dimensional life outdoors. Because the finish penetrates rather than coats, it cannot peel or flake, and maintenance requires no sanding or stripping — just clean the surface and reapply when it looks dry. The clear formulation adds no pigment, allowing the natural honey-gold tone of the pine to show through initially before gradually silvering to a soft gray patina if left unmaintained with a colortone.
Ideal for porch ceilings, tongue-and-groove soffits, traditional lap or shiplap siding, wainscoting, interior paneling, and any application where a refined, straight-grained wood aesthetic is desired.
