Aarrow Acorn 5 Grate Bar Set (x5)

This Aarrow Acorn 5 grate set includes 5 heavy-duty cast iron firebars, designed to replace the original riddling grate system. These bars form the base of the stove’s firebox, supporting solid fuel while allowing ash to fall through for improved airflow and combustion efficiency.

Each firebar is cast to the AFS001 specification, making them a direct fit for models that originally used NGB1B-stamped bars. Measuring approximately 220mm in length and weighing around 0.65kg per bar, they offer excellent durability under high temperatures. For best results, we recommend replacing the entire set at once to ensure smooth operation.

🔥 Why replace your Aarrow Acorn 5 grate bars?

Cracked or distorted grate bars can block riddling and reduce airflow, leading to poor combustion. A full replacement set helps maintain clean burning, maximises fuel efficiency, and protects your stove’s interior from excess heat stress.
