The Simpson Strong-Tie EB-TY EB332W Premium Hidden Deck-Fastening System is the ideal solution that blends strength with ease of installation in a fastener that won't detract from the deck's finished appearance. Simpson Strong-Tie has redesigned the award-winning EB-TY Hidden Deck-Fastening System by integrating a Type 300 series stainless-steel reinforcing plate that adds stiffness to hold boards in place securely, yet maintains flexibility when seasonal contraction and expansion occur. Combine this innovative new design with the included EB-GUIDE predrilling tool, and you have a system that not only provides hidden strength, but is also easy to install. This kit - Model No. EB332WDR100 - includes 100 premium biscuits along with all necessary hardware and installation accessories to get your project done right.
