The TC-G butt seam clip has been specifically designed for butt seam applications when building with the TC-G hidden fastening system. This clip has been designed as a mirror image of the TC-G clip allowing an installer to install two clips per joist at the butt seams. This eliminates the need for additional joists and creates a much stronger connection. The clip 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.
