MiTek’s LTS19-TZ Deck Lateral Load Connector meets the 750 lb. requirement listed in the new 2015 IRC Figure R507.2.3(2). It can be installed just as shown in the IRC figure. Individual pieces will cost about $10.
You’ll need to make 4 lateral load connections using the new 750 lb. connector according to the code. Two of them within 24 in. of the ends of the deck and the others spaced evenly along the ledger.
The LTS19-TZ fastens to the house using a 3/8 in. diameter galvanized lag screw. There is a 13/16 in. diameter hole thorough the rectangular reinforcing plate at the end of the connector so you’ll need to use a washer under the head of the lag screw. The large hole gives you some vertical adjustment to hit the center of the plate or mudsill. Per the code drawing, you’ll need to predrill the framing before driving the lag screw. Per NDS (an IRC referenced standard) the pilot hole (termed a ‘lead’ hole) has a range of diameters based on the species of wood. A quick round figure that seems to work for all common deck lumber species is 3/16 in. diameter.
The strap leg of the LTS19-TZ is 22 1/4 in. long and is fastened to the joist with 8 – 10d galvanized nails (3 in. x 0.148 dia.).
