These issues must be communicated to your installer and/or the fastener company. Movement of Boards due to fastener failure is not covered by Gossen's Warranty.

Gossen fastener Deckmaster clip Important Considerations When Selecting a Hidden Fastener
  • Fasteners must hold Board securely to the joist (do not use fasteners that allow for Board movement of any kind).
  • Groove dimensions: 5/32" wide x 3/8" deep (0.420" profile)
  • Hidden fasteners are not recommended for installations above 6,500 feet.
  • For greater rigidity, consider 12"-on-center joist spacing, especially when using hidden fasteners.
  • To prevent movement, face-screw or toe-screw at butt joints.
  • Grabber Deckmaster G5 clips have been tested and approved for use with Gossen Kerfed Decking. Other hidden fastening systems not mentioned have not been third party tested. Therefore, Gossen does not recommend them.
