MoistureShield Navigator Stair Rail Kit - 36″ Height

The Navigator series delivers the only composite stair rail kit with silent operation engineering and a paintable acrylic cap for customization. This 36-inch height option meets residential code requirements while eliminating the squeaks and rattles that plague standard composite railings.

Hidden Brackets and Silent Operation

Hidden bracket system (concealed fasteners) for a clean look sets Navigator apart from visible-fastener systems. More importantly, Silent operation: engineered for no squeaks or rattles addresses a real jobsite complaint. Standard composite railings develop noise over time as materials expand and contract. Navigator’s engineering prevents this.

The concealed mounting system does more than hide screws. Brackets are concealed behind the rail for a seamless appearance. This matters for stairways where railings get inspected up close every day.

True-to-length panels for easier planning/installation means contractors get what they measure. No surprises on cut day.

Specifications and Code Compliance

The Code compliant for safety and security in residential and commercial applications certification matters for permit approval. Having that PFS-TECO report number ready saves contractors time at the building department.

Three infill options provide flexibility:

• Square Vinyl/Composite: 1-1/8”
• Round Aluminum: 3/4”
• Stainless Steel Cable: 1/8”

Material Quality and Customization

Solid Core™ composite with paintable acrylic cap stock differentiates Navigator from vinyl-capped competitors. Acrylic takes paint better than vinyl. The Satin White (looks/feels like real wood) finish provides a quality starting point, but contractors can match any trim color the homeowner wants.

Architectural detailing on posts and balusters adds visual interest beyond basic composite profiles. Superior moisture resistance: will not rot, splinter, warp, or stain — standard for MoistureShield but worth noting for Montana’s freeze-thaw cycles.

The Navigator is premium with a satin acrylic finish compared to Discovery’s glossy vinyl cap. That acrylic material choice enables the paintability that sets this system apart.

Installation Process

Installation follows a straightforward sequence:

1. Measure stair stringer angle and distance between posts.
2. Cut top beam and bottom beam cover to length (specific angles for Contempo/Capital).
3. Mount hidden brackets to posts using supplied fasteners.
4. Install chosen infill (balusters or cable) into brackets.
5. Secure top rail cover (sold separately) over the top beam.
6. Verify rail height of 36” and gap spacing to ensure code compliance.

Full installation instructions available at the manufacturer’s website provide detailed diagrams for each top rail style.

The Bottom Line

Navigator stair rail kits solve real problems — squeaky railings and limited customization options. The hidden bracket system with silent operation engineering works. The paintable acrylic cap beats vinyl for contractors who need color matching. At 36 inches, this kit meets residential code while offering three infill styles for design flexibility.

Transferable Limited Lifetime Warranty; Covers rot, splintering, warping, and staining under normal use. Transferable to subsequent owners. That transferability adds value for resale.

For Montana contractors dealing with freeze-thaw cycles and homeowners who want railings that match their trim color, Navigator delivers. The silent operation alone justifies the premium over standard composite systems. Add the IRC/IBC compliance documentation and Made in USA designation, and you’ve got a system that works for both permitted jobs and quality-focused installations.

Frequently Asked Questions

What makes the Navigator series “silent” compared to other composite railings?

The hidden bracket system and engineering prevent the squeaks and rattles that develop in standard composite railings as materials expand and contract. Concealed fasteners eliminate metal-on-metal contact points.

Can I really paint the acrylic cap?

Yes. The acrylic cap stock takes paint better than vinyl caps. Start with the satin white finish and apply quality exterior paint designed for plastics. This sets Navigator apart from vinyl-capped systems that don’t hold paint well.

What’s the actual code height requirement for residential stairs in Montana?

Montana follows IRC, which requires 34 inches minimum measured vertically from the nose of the stair tread. The 36-inch Navigator kit provides 2 inches of safety margin above code minimum.

Do I need to buy posts separately?

Yes. Posts, post sleeves, and post caps are sold separately. The kit includes rails, brackets, fasteners, and balusters (for square baluster version only).

Which infill option works best for Montana weather?

All three options handle Montana conditions. Square composite balusters match the rail material. Aluminum balusters offer a modern look with no maintenance. Cable provides maximum visibility but requires proper tensioning.

How does Navigator compare to MoistureShield’s Discovery series?

Navigator features a satin finish with paintable acrylic cap versus Discovery’s glossy vinyl cap. Navigator offers more architectural top rail styles and focuses on premium aesthetics with silent operation.
