The Navigator 42-inch rail kit brings something unique to Montana deck builders: a paintable acrylic cap on solid core composite construction. Built for commercial-height requirements, this 8-foot kit handles the 42-inch code demands of multi-family projects while offering customization that other composites can’t match.
Paintable Cap Technology Sets Navigator Apart
That paintable acrylic cap changes the game. While competitors lock you into factory colors, Navigator’s Satin White finish accepts paint for custom matching. The acrylic layer provides UV and impact protection while allowing contractors to match specific architectural requirements — critical for Montana’s resort communities where HOAs dictate exact color schemes.
The cap sits atop a solid core wood-plastic composite that resists moisture, rot, insects, and impact. This solid construction differs fundamentally from hollow-core competitors. No water pooling inside. No freeze expansion cracking the rails. The solid material throughout means consistent strength even after Montana’s temperature swings work their magic.

Commercial Height Requirements Drive the 42-Inch Design
The 42-inch height meets commercial building codes — not just a preference but a requirement for multi-family decks, commercial properties, and certain residential applications. Montana contractors working on apartment complexes, restaurants with deck seating, or any elevated commercial deck need this height to pass inspection.
The system includes hidden brackets that conceal fasteners for clean aesthetics. This hidden bracket system earned praise from users for both looks and function. Installation requires precision — a drill guide comes in the kit for proper bracket alignment. Smart contractors paint the rails before final assembly if custom colors are needed.
The kit includes four mounting brackets per 8-foot section, plus a drill guide for alignment. Posts aren’t included — they’re sold separately. The system works with Navigator composite posts or standard wood posts with sleeves.
Installation Details and Compatibility
Installation hits the moderate difficulty level. The process follows a logical sequence:
- Measure and cut posts
- Mark bracket locations using provided drill guide
- Install top and bottom beams
- Insert balusters and snap into place
- Apply top rail cover (acrylic cap)
The system accepts three infill options: 1-1/8 inch Square Vinyl Balusters (standard in kit), 3/4 inch Round Aluminum Balusters, or 1/8 inch Stainless Steel Cable. MoistureShield LED lighting accessories integrate with the system for those deck projects where evening ambiance matters.

Warranty and Long-Term Performance
MoistureShield backs the Navigator with a Transferable Limited Lifetime Warranty covering material defects, rot, decay, and insect damage. The company claims zero structural field failures for more than 30 years — a bold statement that matters when you’re building decks expected to handle snow loads and temperature extremes.
Users report the system feels “extremely sturdy” with “aesthetic flexibility.” The main complaint centers on premium pricing and the need for precise installation. Fair points. This isn’t the cheapest rail system. But for commercial projects where code compliance, customization, and long-term durability justify the investment, Navigator delivers what contractors need.
FAQ
Q: Can I use standard 36-inch rail heights for residential projects?
A: Navigator offers both 36” and 42” heights in 6’ or 8’ lengths. The 36-inch version works for standard residential applications. Choose 42-inch for commercial projects, multi-family buildings, or anywhere code requires the extra height.
Q: What makes the paintable cap different from regular composite?
A: The paintable acrylic cap accepts paint while providing UV and impact protection. Most composite rails come in fixed colors that can’t be painted. Navigator’s white cap lets contractors match exact architectural specifications — crucial for HOA compliance or commercial color schemes.
Q: How does solid core construction handle Montana winters?
A: Solid core means no hollow spaces for water to collect and freeze. The wood-plastic composite resists moisture, rot, and insects throughout the material. Unlike hollow rails that can trap water and crack during freeze-thaw cycles, solid core maintains consistent strength.
Q: Do I need special tools for installation?
A: The kit includes a drill guide for bracket alignment. Standard deck-building tools handle the rest. The hidden bracket system requires careful measurement but doesn’t demand specialized equipment beyond what contractors already own.
Q: What’s the actual coverage per kit?
A: Each kit covers 8 feet of railing at 42-inch height. Twenty balusters come standard. Calculate your linear footage and remember to order posts separately — they don’t come in the base kit.
