About this product

The DeckWise 5/4 Hidden Siding Fastener Kit is a specialized rainscreen attachment system designed to provide a fastener-free surface for thick tropical hardwood cladding. It eliminates the need for face-screwing, solving the problem of visible screw heads and potential water intrusion points in premium exterior siding. This kit is specifically engineered for contractors and homeowners installing 5/4 (actual 15/16") thickness profiles in high-density species.

Constructed from solid 304-grade stainless steel to resist rust and chemical corrosion in exterior environments.

Features a dual-hole design that allows for secure 45-degree screw penetration, essential for vertical and overhead applications.

Includes a complete installation package with starter clips and T15 star-drive stainless steel trim-head screws.

Engineered to facilitate a rainscreen air gap, significantly reducing the risk of cupping and mold growth in dense hardwoods.

Protected under U.S. Patent No. D663,612 S.

Best used for

1Residential Ipe or Cumaru rainscreen siding where a sleek, fastener-free aesthetic is required for modern architectural designs.
2Vertical cladding installations using Tigerwood or Garapa, utilizing the secondary affixing hole to prevent board slip or sagging.
3Soffit and overhead porch ceilings where face-fastening Massaranduba or Red Balau would be aesthetically disruptive or difficult to execute.
4Commercial building envelopes where long-term durability and resistance to cupping are required for thick hardwood profiles.

Pro tips for dense hardwoods

Always pre-drill pilot holes through the tropical hardwood at a 45-degree angle to prevent splitting the board edge or snapping the stainless steel screws.
Apply a high-quality end-grain sealer to all fresh cuts immediately to prevent end-checking, which is common in high-density species like Ipe and Cumaru.
Ensure siding boards have acclimated to the local environment for at least 7–14 days before installation to minimize post-install movement.
When installing butt joints, use two fasteners (one on each board end) to ensure the joint remains tight and flush over time.
