TECHNICAL MODEL / VERIFICATION GATE

Manufacturer evidence & supplied-fit review

Reference reconstructions explain the documented mechanism. Their inferred details are labeled separately; matching the actual supplied board, accessory SKU and current instructions remains a separate review.

Exact system: Ipe Clip Extreme
Manufacturer / system record: DeckWise
Application: Decking
Installation reference: Published documents linked below; these do not verify the supplied board profile.
Geometry status: Reference reconstruction where available; current production geometry remains unverified
Production groove / profile: Verification pending — nominal size does not establish engagement.
Published screw configuration: #8 × 2-inch stainless T15 is a published kit configuration. Other lengths/alloys exist; match the supplied kit and joist. Do not treat all stainless screws as interchangeable.

Ipe Clip Extreme

The 3/32-inch gap model, with an angled through-board attachment for hardwood.

Material scope: Air-dried hardwood; the product page also lists composite/PVC. Consult the species chart before choosing the gap.
First check: The linked Ipe Clip warranty requires authorized-dealer purchase and registration within 45 days, excludes improper installation, and does not pay removal/reinstallation costs. Read the current terms.

Ipe Clip Extreme-S

A 5/32-inch spacing system for the material categories named by DeckWise.

Material scope: Air-dried or kiln-dried hardwood, composite and PVC are listed categories.
First check: The current page uses Extreme-S; older tables use Extreme4. Do not transfer a species-specific Extreme4 result to an Extreme-S kit without manufacturer confirmation.

Ipe Clip ExtremeKD

A 1/4-inch spacing model. Larger spacing does not make every species suitable.

Material scope: Kiln-dried wood, composite and PVC categories; consult drying-specific results.
First check: In the species chart, kiln-dried Massaranduba is listed for ExtremeKD but rejected for Extreme and Extreme4. Do not collapse the three models into a single “Ipe Clip compatible” label.

EB-TY Premium

A reinforced biscuit system that fastens through the wood into the joist.

Material scope: Ipe and other exotic hardwoods, redwood and cedar. Premium wood kits are distinct from original composite kits.
First check: EB332W: 3/32-inch gap for air-dried decking. EB316W: 3/16 inch and EB14W: 1/4 inch for kiln-dried decking; the catalog gives 3/4–1-1/2-inch board thickness.

EB-TY Original — composite kits

The composite listings are original EB-TY, not steel-reinforced EB-TY Premium.

Material scope: Composite decking category; exact decking-brand approval still needs confirmation.
First check: C-F-2025 identifies 175-EBTYP and 175-EB TT as original products without a steel reinforcement plate.

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.

DeckWise chart: exact model names retained
Species / condition	Extreme	Extreme4 (legacy)	ExtremeKD
Ipe · air-dried 16–20%	Listed	Listed	Rejected: excessive gap after shrinkage
Pine · air- or kiln-dried	Rejected	Rejected	Rejected
Tigerwood · kiln-dried	Rejected	Listed	Listed
