Stairparts
We have a wide range of stock and custom stair parts to meet your projects requirements.
Stairparts
Whether you are building a stair, or replacing parts on an existing stair, most of our stairs are constructed on-site at our manufacturing facility in Somerset, MA. We offer the largest variety of in-stock and special order stair parts in the region, or we can custom build parts to your exact specifications. The quality of our stairparts is unmatched.
You can find drawings for our most popular stair layouts in our Stairs CAD Library as well as drawings for balusters, posts and handrails.
In addition to our own line of stairparts, we are also a dealer for Fitts, House of Forgings, Prestige Metal, and Custom Iron.

Large Selection of Handrail and Fittings
Handrail and fittings
A perfectly designed handrail profile strikes a delicate balance between form and function. A safe handrail must be easy to grasp by any size hand. A beautiful handrail mirrors the other architectural elements of the home and looks stunning from both above and below. We are proud to offer handrail from Fitts as well as our customer Cooper Stair parts handrail. All Cooper handrail and fittings are made in our own shop and available in many wood species.

Large Selection of Box Newels
Box Newels

Fasteners and Accessories
Zipbolts Fasteners
The ZIPBOLT™ UT Rail Bolt uses the same hole boring configuration as traditional rail bolts, but its ease of installation makes it very different. The ZIPBOLT™ UT one-piece totally integrated gear head replaces the old nut and washer making it quick and simple to join stair parts together using common bits and drivers. Instead of trying to fit a nut and wrench into a 1″ hole, the installer easily tightens the bolt with a hex driver bit and an adjustable torque drill or ratcheting screwdriver, or a simple allen wrench can be used.
Accessories
Plugs, fasteners, brackets – we have everything you need for clean installation.
