Structural building product manufacturer Simpson Strong-Tie has acquired Blue Heron Enterprises, manufacturer of EB-TY biscuit-style hidden deck fasteners. It has also acquired Fox Chase Enterprises, which manufacturers Lumber Loc deck fasteners, a similar biscuit-style system. EB-TY first introduced its polypropylene fasteners, which are designed to fit in #20 biscuit slots cut in the sides of the deck boards, back in 1997. Lumber Loc clips are designed to work in both biscuit slots and in grooves milled into the sides of the decking. Simpson previously offered its own hidden fastener, called the DBT1Z Deck-Tie, which was discontinued in 2010 when SST began promoting EB-TY fasteners.
