NMFC 126156 - Garage Door Operators | Density-Based Class

To find the correct freight class for your shipment:

1. Calculate package density (PCF) for each carton and list it on the BOL; example: 36 lb in 2.8 cu ft = 12.9 PCF for density-based rating under Item 170.
2. Use robust boxes with molded foam or suspension packaging to protect the motor head and logic board; bag fasteners and wall controls separately inside the master carton.
3. If rails, belts, or photo-eyes ship in separate boxes, label each carton clearly and book them on the same NMFC item to avoid split classifications.
4. Palletize cartons upright, strap twice in each direction, and wrap to the pallet; mark fragile control housings and avoid unnecessary ‘Do Not Top Load’ stickers that can trigger fees.

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

• Density-based rating rewards compact, right-sized packaging, often lowering freight class and cutting LTL costs for opener kits.
• Boxed packaging aligned to Item 170 reduces reweigh/reclass disputes and shortens audit cycles with carriers.
• Clear NMFC identification streamlines quoting and contract pricing, enabling more predictable freight rates across SKUs.
• Damage reduction on motor assemblies and electronics decreases claims and downtime for installers and facility managers.
