MoistureShield Navigator Solid Core Composite Railing - Cable Infill

MoistureShield’s Navigator cable railing combines the unobstructed views of stainless steel cable with the durability of solid composite posts and rails. The system uses 1/8-inch 316 stainless steel cable infill with Solid Core™ cell-filled polymer composite structural components, delivering mountain views without the maintenance headaches of wood or the cold industrial feel of aluminum.

For Montana contractors building decks where the view matters as much as the structure, this railing system offers a genuine alternative to traditional balusters. The cable provides the most open view compared to square vinyl or round aluminum balusters, while the solid core construction handles freeze-thaw cycles better than hollow alternatives.

Core Technology and Construction

The Navigator’s strength comes from its Solid Core™ Technology: Dense core resists rot, insects, warp, and moisture intrusion. This isn’t hollow composite that can trap water and crack during Montana’s temperature swings. Higher density and lower water absorption due to Solid Core technology means the material won’t degrade from the inside out when moisture inevitably finds its way into fastener holes.

The acrylic cap protects against impact and scratching and is paintable for color matching, while the TruTexture™ Surface mimics real wood look and feel. That paintable cap matters when homeowners want to match existing trim colors or change their minds five years down the road.

Key Specifications

Specification	Value
Cable Material	1/8-inch 316 Stainless Steel Cable

The true-to-length panels minimize field trimming and waste — sections arrive at actual 6 or 8 feet, not the nominal measurements that leave contractors cutting every piece.

Installation Reality

Hidden bracket system provides concealed fasteners for a clean, craftsman-like appearance. The installation sequence runs straightforward: Install 5x5 post sleeves over structural posts. Attach concealed brackets to posts at the correct height. Mount top and bottom beams onto the brackets. Thread 1/8” stainless steel cable through pre-drilled holes in the beams. Tension the cable using supplied fittings to meet local code (typically 3” maximum spacing). Apply top rail cover and post caps for a finished look.

The system is designed for MoistureShield 5x5 post sleeves but remains compatible with 4x4 wood posts using inserts. This flexibility matters when retrofitting existing decks or working with code-required post sizes.

For commercial projects, IBC compliance requires an IBC Stiffener for 42” height spans over 91” — a critical detail for multi-family projects or elevated commercial decks.

What’s Included vs. What You’ll Buy Separately

Brackets are supplied in kits; cable infill and top rail covers are often sold as separate components. The cable comes in 100 ft or 500 ft cable reels with cable fittings (tensioners and end caps) and a cable release key.

Where It Works Best

Superior resistance to rot and insects with no annual sanding or staining required makes this system practical for Montana’s short building season. While designed to match MoistureShield composite decking lines (Vision, Elevate, Meridian), it’s compatible with other decking systems.

The cable infill excels on elevated decks where views justify the investment, lakefront properties where reflection off water matters, and modern mountain homes where traditional balusters would block the scenery. MoistureShield brand sentiment is generally positive for product durability and industry-leading moisture protection, backed by their claim of zero structural field failures for more than 30 years.

Frequently Asked Questions

Q: What’s the actual spacing between cables to meet code? Tension the cable using supplied fittings to meet local code (typically 3” maximum spacing). Most jurisdictions require the 4-inch sphere test — cables must be close enough that a 4-inch ball can’t pass through.

Q: Can this system handle Montana snow loads on elevated decks? The Solid Core™ cell-filled polymer composite construction provides higher density than hollow railings. The system meets both IRC and IBC code requirements, though elevated commercial applications need additional stiffeners for longer spans.

Q: How does cable tensioning hold up through freeze-thaw cycles? 316 stainless steel cable handles temperature swings without the expansion issues of cheaper materials. The system includes a cable release key for adjustments when needed.

Q: Is the white color stable or will it yellow? The acrylic cap provides UV protection, and it’s paintable for color matching if preferences change. Only 2 colors are available from the factory.

Q: What’s the real difference between this and aluminum cable railing? Quieter under foot traffic; no corrosion; maintains a warmer, wood-like aesthetic. The composite posts and rails don’t conduct cold like aluminum, making winter handrail contact less jarring.
