Secure Your Freight with the Rockcub 48" x 84" WPP Jumbo Dunnage Solution
When transporting high-value assets, standard void fillers aren't enough. The Rockcub Jumbo Dunnage Air Bag is the industry's answer to large-scale cargo protection. Featuring a reinforced Woven Polypropylene exterior and a high-performance 2.9 PSI pressure rating, these bags are built to stabilize heavy loads in 53ft trailers, railcars, and ocean containers.
Why 2.9 PSI Matters: In logistics, a loose load is a damaged load. Our bags provide a more "rock-solid" brace by allowing higher internal pressure, securing wide voids between pallets or machinery that would otherwise require expensive timber bracing or multiple smaller bags.
Engineered for Every Shipping Scenario:
Standard & Oversized Pallets: Bridge the gap between pallet rows to prevent lateral leaning and shifting.
Industrial Crates & Machinery: Secure heavy wooden bracing and equipment against container walls.
Barrels & Drums: Perfectly fills the large, irregular gaps created by cylindrical loads.
Weatherproof Performance: Our waterproof WPP material remains 100% effective in humid or cold-chain environments, ensuring reliability regardless of the weather.
Technical Specifications:
Flat Size: 48" x 84" (122 x 213 cm)
Max Operating Pressure: 2.9 PSI (20 kPa)
Material: Heavy-Duty Woven Polypropylene (WPP)
Valve Type: Reusable Fast-Fill Spring Valve
Application: Trucking, Shipping Containers, Railcars, and Intermodal Freight.
This bag flat-packs at 48" x 84" to fill voids between pallets, crates, or drums. Use the spring valve to control fill level and match narrower gaps without over-inflating.
Free shipping to every address in the contiguous United States.
Smaller items — parts, accessories, strap and film — ship by UPS or FedEx with tracking. Large machines ship by freight on a pallet, and liftgate service is included at no extra charge: the driver lowers the shipment to ground level, so no loading dock or forklift is needed on your end.
Someone needs to be available to receive and sign for a freight delivery. Inspect the shipment for visible damage and note it on the delivery receipt before signing.
