RB73 Ker Mobile Wood Storage | CorTen Steel Transport Solution

The Ker eliminates multiple trips between wood storage and the fireplace with simple wheeled efficiency. Measuring 58 x 60 x 99 centimeters (23 x 24 x 39 inches), this mobile trolley transports substantial wood loads across outdoor surfaces while maintaining the industrial aesthetic of the RB73 collection. Built from durable 2mm CorTen steel, it develops the same weathering patina as your outdoor fireplace. An optional Iroko hardwood shelf transforms the trolley into a complete fireside station for tools and accessories. Wood transport, solved.

Complimentary shipping included on all RB73 accessories.

DIY Assembly with Professional Construction

Supplied as a comprehensive kit designed for straightforward assembly without specialized tools. The precisely engineered components fit together with satisfying precision, while the wheeled design allows effortless transport despite the substantial 41kg (90 lb) build quality. The optional hardwood shelf matches the same premium Iroko wood used in the BloX storage series, creating consistent material language across your outdoor setup.

The Beauty of CorTen Steel

RB73 accessories are built from CorTen steel, a 100% recyclable metal alloy developed by US Steel designed to age gracefully outdoors. Copper, silicon, nickel, and chromium are added to iron to create CorTen steel, a process that develops a protective rust-like patina that deepens over time, shifting from warm orange tones to a rich, earthy brown. This evolving surface doesn't weaken the structure—instead, it shields the trolley from further corrosion, allowing it to withstand the elements season after season (CorTen steel lasts about 10x longer than regular steel).

No two pieces will weather in the same way, which means each Ker develops its own unique character. The result is a transport solution that doesn't just function beautifully, but also tells a story of time and place, growing more integrated into its surroundings with every year.

Pair the Ker with Gränsfors Bruk wood axes for complete wood preparation and transport efficiency.
