Simpson StrongTies DTC Roof Truss Clip installs easily from above using four 8d common nails in the base and two 8d nails inside the slot, which should be fitted loosely to permit movement. The engineered swages provide stiffness without hindering chord yield. At only 0.15lb per clip, the DTC offers practical alignment features without burdening walls or complicating framing layout making it ideal for clean, code-sensitive truss-to-wall assemblies.
