DeckWise Short Clips will work on any board, but some people choose to use the tall clips.
DeckWise Short Clips will work on any board thickness, but the tall clips are ordered for what the industry describes as "5/4 Board", which means any board thickness exceeding 1".
DeckWise Extreme Clips or DeckWise Extreme4 Clips work on all hardwoods. However, the DeckWise ExtremeKD Clip is typically used on composite decking because it provides the 1/4" gap spacing that many composite boards require.
DeckWise Tall Clips are available for Extreme and Standard Ipe Clips. *Tall Clips are not available in Extreme 4 or Extreme KD.
