Installation Tip
Use on rainscreen and cladding installations with proper furring strips.
DeckWise® Hidden Siding Fasteners create an upscale, fastener-free appearance on hardwood rainscreen siding installations. Designed for 5/4" thick siding profiles, these marine-grade aluminum clips attach to furring strips behind the siding, completely concealing all fasteners from view. The system prevents cupping, twisting, and mold growth by allowing air circulation behind the siding and accommodating natural wood movement. Each clip spaces the siding from the wall for proper rainscreen drainage. 90-count kit for larger siding projects.

Why Choose Hidden Fasteners?
How Hidden Fasteners Work on Hardwood Decks
Pre-Groove the Boards
Hidden fasteners require a slot machined into the edge of each board. Most boards from Ipe Woods USA ship pre-grooved, or you can route the slot on-site with a 1/8″ slotting cutter.
Set the First Board
Secure your starter board to the joist with a face screw near the house-side edge. This first board anchors the rest of the field and will be covered by trim.
Clip, Screw, Slide
Insert the clip into the board groove, drive the supplied screw through the clip into the joist at roughly 45°, then slide the next board onto the exposed clip tab. The built-in spacer legs set the gap automatically.
Repeat Across the Deck
Continue across the deck, one board at a time. Each clip grips the outgoing board while spacing the incoming one — no measuring or shimming needed.
Pro Tip from Our Deck Specialists
In hot weather, tighten clips snugly but not crushing-tight. Exotic hardwoods expand and contract with moisture changes, and the clip must allow sideways movement to prevent buckling.
