RailFX RFX100 Round Top Rail - Picket Rail System

RailFX’s RFX100 Round Top Rail is a high-grade aluminum railing system with a 2-inch diameter graspable round profile specifically designed for stair applications. The system offers contractors an all-in-one solution with pre-drilled components and on-site trimmable rails. For Montana contractors dealing with freeze-thaw cycles and temperature extremes, aluminum’s rust-free properties solve the corrosion problems that plague steel railings.

Installation Speed and Code Compliance

The RFX100 cuts installation time through smart engineering. Pre-drilled components hide hardware and fasteners, eliminating the tedious layout and drilling that eats up labor hours. The on-site trimmable top rail means contractors don’t need exact measurements before ordering — they can cut to fit on location.

The 2-inch diameter round graspable profile meets ADA/Code requirements for stair handrails. Montana contractors working on both residential and commercial projects get one system that satisfies IBC and IRC compliance. The system offers 36-inch and 42-inch rail height options to meet different code requirements.

Weather Resistance for Montana Conditions

High-grade extruded aluminum that never rusts addresses Montana’s moisture challenges head-on. Spring snowmelt, summer thunderstorms, and winter freeze-thaw cycles can’t touch aluminum the way they destroy steel components. The AAMA 2604 certified powder coating adds another layer of protection.

The finish warranty backs up the durability claims. The coating is guaranteed against cracking, chipping, blistering, or peeling per AAMA 2604 standards. RailFX provides a Limited Lifetime Warranty on structural integrity and finish, plus a 4 Year Prorated Limited Labor Warranty.

The system offers multiple finish options including Textured Black, White, Bronze, Silver, and Custom Powder Coat Colors. The textured black and bronze finishes blend naturally with Montana’s landscape aesthetics while hiding the dust and pollen that shows on glossy surfaces.

The mounting options adapt to different deck configurations: Surface Mounting uses 2-inch case hardened screws for post-to-deck attachment, Fascia Mounting offers side-mount brackets or direct-to-rim joist connection, and Core Mounting sets posts in concrete with non-shrinking grout.

The Contractor’s Take

Homeowners frequently mention the value of the ‘all-in-one’ kit approach which simplifies ordering. No chasing down compatible components or discovering missing pieces mid-installation. The system’s compatibility extends to Picket, Cable, and Glass infill systems, giving contractors flexibility to match different architectural styles.

The 6-foot post spacing capability reduces material costs on large deck projects — a real advantage when bidding Montana’s sprawling residential decks. Fewer posts mean less drilling, less concrete, and faster installation.

Testimonials highlight high satisfaction with the ‘professional’ appearance and ‘easy-to-install’ nature of the system. For contractors who understand that callbacks kill profits, a system that installs cleanly and stays looking good matters more than superior performance at higher initial investment.

FAQ

What tools do I need to install the RFX100 system?

Installation requires a miter saw with aluminum blade, drill and bits, measuring tape, rubber mallet, and level. Standard contractor tools handle the job — no specialty equipment needed.

Can this system work with wood posts?

Yes. The RFX100 is compatible with wood posts using post-to-post rail installation, though most installations use 3-inch aluminum posts for consistency and durability.

Is this specifically a stair rail or can it work on level decks?

While the graspable round profile is specifically designed for stair applications, the system handles residential decks, balconies, and patios equally well. The round profile just happens to meet stair handrail code requirements.

How does the finish hold up near water?

The aluminum construction makes it suitable for waterfront and coastal installations. Unlike steel systems that rust from the inside out, aluminum stays structurally sound even with constant moisture exposure.
