What the manufacturer actually lists
Ipe and other exotic hardwoods, redwood and cedar. Premium wood kits are distinct from original composite kits.
Named species / categories
Ipe · Redwood · Cedar
Explicit exclusions
No exhaustive exclusion list found. Absence of a prohibition is not approval.
Conditions that change the answer
- 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.
- WP kits with 1-5/8-inch screws are specifically for roof decks on 1-inch sleepers. They are not the default substitute for WD kits.
- C-F-2025 describes kiln-dried as generally ≤19% moisture and air-dried as generally >19%; this convention differs from DeckWise’s chart. Do not combine their thresholds.
- A species name alone does not approve the supplied profile, moisture condition, screw or exposure.
- For saltwater, pool chemicals or treated substrates, verify the complete metal combination and manufacturer corrosion guidance. A stainless insert is not a blanket marine approval.

Reference-inferred or illustrative features
- Arc curvature, chamfer and central reinforcement outline reconstructed from orthographic views
- Current US model equivalence remains pending
- Screw shape illustrative; use exact current US kit evidence separately
Supplied production fit: pending. A recognizable model does not change the compatibility result. The board shown explains a manufacturer interface, not approved Ipe Woods milling.
A · Verified technical model — Geometry from approved CAD or dimensional drawings; only verified dimensions are displayed.
B · Reference reconstructed — Source-faithful visual model. Inferred details are recorded and unverified manufacturing dimensions are withheld.

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.

- Published screw configuration
- WD: #7 × 2-1/4-inch trim-head, Type 305 or 316 by SKU. WP: #7 × 1-5/8-inch Type 316 for the stated sleeper application. Clip reinforcement is Type 300 series, not a claim that the whole assembly is 316.

Manufacturer installation evidence, manufacturer geometry and supplied production fit are independent verification states. No generated image establishes any of them.
Dimensions belong to different parts
Installed gap, clip size, board thickness and groove cut are separate measurements. Mill tolerances and the sold accessory match remain separate approvals.
| Measurement | Inches | Millimeters | Applies to / limitation |
|---|---|---|---|
| EB332W gap | 0.09375 | 2.381 | Air-dried wood series. |
| EB316W gap | 0.1875 | 4.762 | Kiln-dried wood series. |
| EB14W gap | 0.25 | 6.35 | Kiln-dried wood series. |
| Minimum listed board thickness | 0.75 | 19.05 | Maximum 1-1/2 inch; choose the exact series. |
| Clip envelope / groove tolerance | Unverified | — | Not established by the reviewed catalog. Use the actual biscuit/profile specification; do not copy Ipe Clip groove values. |
Metric values are calculated conversions, not added manufacturing precision.
The screw is part of the system
WD: #7 × 2-1/4-inch trim-head, Type 305 or 316 by SKU. WP: #7 × 1-5/8-inch Type 316 for the stated sleeper application. Clip reinforcement is Type 300 series, not a claim that the whole assembly is 316.
Installation sequence
Identify the exact EB332W, EB316W or EB14W kit and supplied board groove. Establish the starter and last-board face attachment.
Use the EB-GUIDE and 1/8-inch pilot bit for the manufacturer’s angled attachment.
Seat the biscuit in the groove. Drive the matching screw through the biscuit and the first board into the joist.
Slide the next board onto the remaining radius wing. This edge engages the biscuit without a second screw through it.
Resolve joint support, edge details and any adhesive requirement with the current installation instructions for the kit.
