This 4-pack of Global Truss DT-Stack Clip helps you keep your truss neatly stacked when not in use. The plastic clip is suitable for use with 48 to 50mm diameter truss, such as F34/DT34P/DT44P/DT36/DT-GP truss sections. The clips help keep your sections from knocking into each other, which can cause dings and dents that may affect strength and performance. In addition, the clips help prevent your truss sections from sliding when stacked, which can become a safety hazard when stored or transported.
