Stair Parts

A Coordinated System— From Stringer to Cap

Stairs set the tone of a home. Cox Interior engineers wood stair parts as a unified system—stair treads, risers, skirts, handrails, fittings, newels, and balusters—so geometry, code, and design read as one continuous line. Because we manufacture regionally and package for the field, every component arrives labeled, protected, and sequenced to your plan set. The result: faster staging, cleaner installs, and fewer punch-list surprises.

Why Builders Choose Cox Interior for Moulding and Shiplap

Integrated manufacturing (knife grinding, moulders, S4S, fittings) under one roof
Kiln-tuned stability for tight joints after HVAC startup
Knife-true edges and finish-ready faces that paint or stain cleanly
Jobsite-ready packaging with room/run labels and clear manifests
Builder-focused support: proactive dates, small fills, quick clarifications

Complete Stair Solutions

Stair Treads & Landings

Solid hardwood and engineered stair treads in white oak, maple, walnut, cherry (others on request). Return nosings, closed/open tread options, and mitered landings are sized to your rise/run. Faces are sanded to finish-ready grit; edges stay crisp for clean stain lines. Paint- or stain-grade risers coordinate with the spec.

Handrails & Stair Railings

Comfortable grasp profiles sized to code, with eased edges and smooth transitions across changes in pitch. Our stair railings include volutes, over-eases, goosenecks, and returned ends; choose post-to-post or over-the-post paths to match layout, code, and style.

Newels

Box newels with Craftsman, Shaker, or paneled details; turned newels for traditional entries. We right-size cap and shaft dimensions to ceiling height and stair width so proportions feel balanced in both foyers and open galleries.

Balusters

Paint- or stain-grade wood balusters, or iron patterns with matching shoes/knuckles—kitted by run for quick spacing and inspection. Alternating single/double knuckle or basket rhythms create visual interest without clutter.

Style Families That Scale Correctly

Classic Craftsman:

square newels, square balusters, eased-edge rail; honest joinery with calm lines

Transitional:

box newels with subtle reveals; square or tapered balusters; streamlined fittings

Traditional:

turned newels/balusters; rail profiles that echo crown/base vocabulary

Modern Minimal:

low-profile rail, square newels, slim iron lines that keep sightlines open

Materials & Finish Performance

Stain-Grade Warmth

White oak, maple, walnut, cherry—selected for color/figure continuity. Knife-true edges and properly prepped end grain help stain lay evenly and wear beautifully.

Paint-Grade Precision

Poplar/MDF placed where each performs best for crisp profiles and minimal telegraphing on risers, skirts, and box newel faces.

Kiln-Dried Stability

Moisture programs tuned for interior conditions common to our markets. Stable stock keeps nosings tight, rail joints quiet, and long skirt runs clean through seasonal swings.

Code-Smart by Design

We plan compliance into the package so field time is installation—not improvisation:

Handrail height and graspability for stair railings
Guard height on balconies and overlooks
4-inch sphere spacing at balusters
Proper rail returns at terminations
Clearances to walls, doors, and landings

We’ll flag stair-to-door headroom conflicts, landing depth, and newel locations early so framing, drywall, and inspections stay coordinated.

Built for the Jobsite—Not the Warehouse

Room/Run Labels:

Each flight, landing, and balcony keyed to your plan

Protected Faces & Edges:

Rail sleeves, corner shields, and nosing protection reduce touch-ups

Kitted Hardware & Fittings:

Shoes, knuckles, and fasteners bagged by run

Clear Manifests:

Pick lists mirror your takeoff so installers grab-and-go

Drivers coordinate realistic windows and stage where work begins, cutting walking, handling, and setup time on tight finish schedules.

Options & Upgrades

ADA-friendly grasp profiles and concealed brackets
Iron/wood hybrid systems for a thinner visual line
Acoustic details (adhesives, screw patterns) for quieter stairs
Prefit rails/fittings for complex balconies and switchbacks
Prefinish options (by scope/lead time) with coordinated field touch-up plans

A Simple, Predictable Process

1) Consult

Share plans, finish targets, species, geometry, and dates. We confirm rail path, newel positions, and baluster pattern, then align on code details.

2) Takeoff

Counts by flight/landing/balcony with fittings, returns, and terminations called out. Long-lead items (special fittings, iron patterns) flagged early.

3) Estimate & Dates

Transparent pricing plus realistic windows you can schedule around. If timelines tighten, we’ll suggest alternates that protect both look and schedule.

4) Production & QC

Knife grinding, rail/fitting fabrication, tread/landing builds, dry-fit of critical joints, verification of pitch blocks and finish prep.

5) Delivery & Field Support

Jobsite-ready bundles staged where work begins. Need a small fill to keep momentum? We turn it fast and coordinate with the superintendent.

Installation Tips for Cleaner Results

Acclimate wood stair parts in conditioned space prior to install
Verify true framing and consistent rise/run before finish work
Glue + screw nosings; pre-drill for clean edges and quiet steps
Use pitch blocks to align rail transitions and maintain continuous height
Seal end grain (including under stair treads) before finish for uniform color and durability
