Tiger Claw TC-3S for Composites - Bucket of 900 - With Screws and 4 Installation Block Tools has been developed specifically for use with composite or synthetic decking materials and some medium density hardwoods.

The TC-3 will work with composite and synthetic decking lumber varieties such as Boardwalk, ChoiceDek, Elements, EverGrain, EverX, Fiberon, GeoDeck, Green Tree (2x4 hollow), LakeShore, Latitude, Monarch, Nexwood, Portico, ProCell, TimberTech (5/4 planking), Trex, UltraDeck, Veka, Weather Best, and WeatherShield.

TC-3 will work with medium density hardwood decking lumber varieties such as Cambara and Meranti.

We do not recommend our fasteners for Correct Deck, TimberTech 2"x6" hollow plank, and Oasis. Unfortunately, due to the design of the materials, installation testing results showed difficulty and require additional skill. Please consult your composite manufacturer or ask us first if you plan to use any other composite or synthetic material not listed above in your decking project.
