What the manufacturer actually lists
Air-dried or kiln-dried hardwood, composite and PVC are listed categories.
Named species / categories
No species-specific listing established for this exact record. The material category above is not blanket approval.
Explicit exclusions
No exhaustive exclusion list found. Absence of a prohibition is not approval.
Conditions that change the answer
- 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.
- Board thickness 1-1/2 inch or more may require a longer screw. The product page calls for at least 1-1/2-inch thickness at widths of 8 inches or more.
- 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.

Sources, confidence and reconstructed details
Current Extreme-S product views and published gap. The legacy Extreme4 drawing is supplementary visual context, not a current dimensional approval.

Reference-inferred or illustrative features
- Body envelope, opening, molded transitions and spacer shape are reference reconstructed
- No inherited Extreme4 species approval or current manufacturing dimensions
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.

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 |
|---|---|---|---|
| Installed gap | 0.15625 | 3.969 | Use the matching spacing tools. |
| Required groove cut | 0.15625 | 3.969 | Manufacturer interface requirement, not clip thickness. |
| Required groove depth | 0.5 | 12.7 | Centered vertically: lower edge = (actual thickness − cut) ÷ 2. |
| Current clip envelope / tolerances | Unverified | — | Needs Verification; legacy Extreme4 dimensions are not assigned to Extreme-S. |
Metric values are calculated conversions, not added manufacturing precision.
The screw is part of the system
Published kit: #8 × 2-inch stainless T15. Confirm exact alloy, length and substrate configuration.
Installation sequence
Establish the starter-board face attachment and plug detail. Verify the selected board and kit before routing.
For the documented Ipe Clip interface, center a 5/32-inch cut, 1/2 inch deep. Check the actual supplied groove.
Hardwood: predrill a 1/8-inch pilot through the board at approximately 45°. Drive the screw through clip, board and into the joist.
Seat the next board on the exposed clip wing. Fasten its opposite edge; do not screw both boards through the same clip. Avoid overdriving.
Composite/PVC uses the manufacturer’s vertical screw path instead. Check the decking brand’s own instructions and kit. Resolve ends, perimeter and board joints separately.
