TC-120 Grooved Board Hidden Deck Fastener for Hardwood

The Tiger Claw TC-120 is the fastest, easiest way to hide fasteners in hardwood decking. The clip has been specifically designed to install 3/4” x 4” or 6” decking that is pre-grooved or grooved with the TC-120 slot cutter. TC-120 is made of 304 grade stainless steel and is approved for use in saltwater applications and ACQ or chemically treated lumber for long-term performance. The clip’s sharp prongs embed into the upper portion of the groove for strong holding power. The stainless steel screw ensures a lasting connection between decking board and joist.

Design features include:

  • Includes #6 x 1 5/8" stainless steel screws
  • Spacer tabs on the clip automatically gap the decking 1/8th to 3/16ths for a consistent look
  • TC-120 reduces wood splitting, wood rot and board cupping. Comes with a 25 year warranty.
  • Can be used with dassoXTR boards.
