NMFC 160370 - HV Line Suspensions in Boxes | Class 60

To find the correct freight class for your shipment:

1. Pack aluminum clamp faces so they cannot rub—use corrugated dividers or foam, and add VCI or light oil wrap for the steel yoke. Example: 8–10 complete sets per box with separators.
2. Cap each box at a manageable weight (40–60 lb) and palletize in a tight footprint. Band and shrink-wrap; mark orientation so clamps don’t shift during LTL cross-dock moves.
3. Print NMFC 160370 and Class 60 on the BOL and carton labels. Note “Non-Hazardous Transmission Hardware” to streamline carrier intake and prevent hazmat confusion.
4. Include a contents sheet showing clamp/yoke counts and the project structure ID. Attach torque spec sheets for field crews to reduce returns and rehandles.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Class 60 rating delivers predictable, mid-tier LTL rates versus generic hardware categories, lowering project shipping costs for utility builds and maintenance windows.
• Boxed packaging reduces damage and reclassification risk, helping avoid carrier inspections, rebills, and schedule slips on energized line outages.
• Simple, non-density classification speeds quoting and tendering—no cube/weight formulas—so procurement teams can lock freight earlier in bid cycles.
• Clean documentation (NMFC 160370 on BOL) improves carrier acceptance and reduces dwell, keeping critical-path components flowing to staging yards.
