Trex 16' Select Saddle Grooved Deck Board

Trex Select Saddle is a 16-foot grooved composite deck board that solves the two biggest Montana deck problems: constant maintenance and unprofessional fastener appearance. The grooved edge profile works with Trex’s Hideaway Hidden Fastening System, giving you a clean deck surface without visible screws. At 5.5 inches actual width and 0.82 inches thick, it’s built for contractors who want efficiency and homeowners who want durability.

Worth it for decks where appearance matters and maintenance doesn’t. The 35-year limited residential warranty backs up the performance claims. Skip it if you’re building a utility deck where nobody sees the fasteners anyway. Standard face-screwed boards cost less and install faster for those applications.

Hidden Fastener System and Installation Efficiency

The grooved edge design specifically accommodates the Trex Hideaway Hidden Fastening System. This isn’t just marketing fluff about aesthetics. Hidden fasteners eliminate the biggest composite decking complaint: mushroomed screw holes that collect dirt and look terrible after two seasons.

Each board runs 16 feet long. That’s 33% fewer seams compared to 12-foot boards. Fewer seams means faster installation and cleaner sight lines down the deck. During Montana’s compressed building season, that efficiency translates directly to labor savings.

The groove profile does more than hide fasteners. It speeds installation because you’re not pre-drilling or countersinking hundreds of face screws. Clip in, move on. The system pulls boards tight and maintains consistent gaps for drainage and expansion.

Weather Performance and Material Specifications

Trex Select uses a high-performance composite blend of wood fibers and recycled plastic. The material composition includes 95% recycled content, which matters more for meeting green building requirements than for performance.

The high-performance shell resists mold, staining, and fading. In Montana’s climate zones, that mold resistance matters. Spring snowmelt keeps decks damp for weeks. Wood needs annual staining to fight mold. This doesn’t.

The Saddle color provides a sunny medium brown tone that hides dirt better than lighter colors. Dark composites get scorching hot in summer sun at elevation. This mid-tone brown balances heat absorption with dirt concealment.

Contractor and Homeowner Reviews

Real-world performance backs up the specs. Reviews average 4.2 stars at Home Depot (160 reviews), 4.3 at Lowe’s (142 reviews), 4.8 at DecksDirect (44 reviews), and 4.4 at The Deck Store (201 reviews). That consistency across retailers suggests genuine satisfaction, not cherry-picked testimonials.

Contractors highlight the high-performance shell’s resistance to weather, stains, and mold, making it suitable for high-traffic outdoor areas. The natural wood-like appearance with a soft, splinter-free finish enhances comfort underfoot.

FAQ

Does the grooved edge work with any hidden fastener system? The grooved profile is specifically designed for the Trex Hideaway Hidden Fastening System. Other clip systems might work, but Trex engineered this groove geometry for their clips. Using off-brand fasteners risks spacing issues and potential warranty problems.

What’s the actual thickness for joist span calculations? The actual thickness is 7/8 inch or 0.82 inches. Don’t use the nominal 1-inch dimension for structural calculations. Follow Trex span tables based on the actual 0.82-inch thickness.

How does Select compare to other Trex lines? Trex Enhance Basics costs less but has a simpler grain pattern. Trex Transcend offers enhanced durability and more color options. Select sits in the middle - better than Basics, more affordable than Transcend.

What about fade resistance in Montana’s UV exposure? The 35-year warranty covers the product, and fade and stain resistance is often included in that coverage for the Select line. Elevation means more UV exposure, but the warranty suggests confidence in long-term color retention.
