In Kim Katwijk’s “Stairbuilding Tips You Missed at the Deck Expo” video on the PDB website, there’s a key detail missing. When you are installing the Simpson Strong-Tie LSC stair bracket shown in the video, the header blocking (or rim joist) that the stairs attach to must extend at least 3 1/2 inches past the point where the stringer is mounted, as shown in the illustration at right.
