A rainscreen is a wall assembly.

Match the cladding profile, clip, fixing and support. A decking clip detail does not establish how siding attaches to a wall.

Four systems. Different details.

DeckWise 1X: aluminum standoff, direct to sheathing, perpendicular screw.
DeckWise 5/4: stainless clip on furring, primary angled screw plus a board attachment for specified orientations.
Original Viking: furring-based system; exact profile and fastener submittal needed.
VC2: separately described no-batten system; do not reuse the original Viking dimensions.

Connection anatomy

Follow the wall attachment

Horizontal field: the primary upper-hole screw fixes the clip into furring. Switch views to see the additional board attachment required for other orientations.

Read with the exact product instructions. Features are simplified for visibility; these are not production drawings or structural details.

Keep flashing, weather-barrier penetrations, drainage, ventilation and wall-load design in the project detail. A clip category alone establishes none of these.

DeckWise 1X Rainscreen

An aluminum standoff clip that attaches directly over structural wood sheathing.

Material scope: Product page names Ipe, Cumaru, Garapa and Western Red Cedar with the required siding profile.
First check: The product is described for 3/4-inch siding, but the linked cutter drawing labels .700-inch thickness. Confirm the approved supplied profile; do not reconcile these values by assumption.

DeckWise 5/4 Hidden Siding

A 304 stainless clip system on furring, with a separate through-board fixing for certain orientations.

Material scope: Hardwood siding with the specified 15/16-inch actual profile. A species-by-species approval list is not given on the reviewed product page.
First check: Do not substitute the aluminum 1X clip or its no-furring detail. Separate starter clips are used here.

Viking Clip — original

The original aluminum rainscreen clip works with vertical furring and a matching siding profile.

Material scope: System literature offers domestic and tropical species; those offerings are not approval of every board sold under the same name.
First check: The original Viking Clip needs furring. VC2 is the separately described no-batten option.

Viking Clip 2 / VC2

A distinct no-batten rainscreen option; original Viking dimensions and schedules cannot be transferred.

Material scope: A wood rainscreen system. Species-level VC2 approval and an exact profile match have not been established from a current technical submittal.
First check: The system owner distinguishes VC2 from the original clip by its no-batten mounting concept.

Read the fine print

Same wood. Different clip. Different answer.

DeckWise’s chart distinguishes species and drying condition. “Listed” is a conditional manufacturer listing, not approval of your supplied board or assembly.
