What's Included in This Complete Set
This is a full replacement kit, containing all the cast components required for the grate assembly in a standard 12hp firebox. Each set includes:
2x Grate Support Pieces
4x 3-Bar Grates
1x 2-Bar Grate
These grates are cast from patterns 3D scanned from original parts, ensuring they fit and function together just like the originals. We use a high-grade, ductile cast iron specifically formulated to withstand the intense heat and thermal cycling inside a working firebox, offering a much longer service life.
