20×20mm to 25×25mm Conversion Trays (OM)

20×20mm to 25×25mm Conversion Trays (OM)

Conversion trays for figures mounted on 20×20mm bases, positioning each model centrally within a nominal 25×25mm Oathmark base position.

Choose your tray size to select a 5×1, 5×2, 5×3 or 5×4 formation. All matching 20×20mm MDF bases are included as standard.

Each set includes a solid 2mm MDF lower layer, a separate conversion insert, the outer movement-tray frame and all matching bases. The conversion insert defines the playable unit footprint: 125×25mm, 125×50mm, 125×75mm or 125×100mm depending on the selected formation. Its visible outer edge marks where the converted base footprint ends.

The movement-tray frame then extends a further 6.35mm (1/4") beyond the conversion insert on every side. This makes the unit footprint distinct from the tray frame for measuring during play. The frame, conversion insert and supplied bases use the selected Frame & Base Thickness of 2mm MDF or 3mm MDF.
