Product overview
Place a miniature on its 20mm square base into one of these converters and it reads as a 25mm square base — no rebasing, no glue, no magnets, nothing removed from the model. It is the straightforward way to bring an older rank-and-file collection up to the newer base size without touching the paintwork, useful for historical armies and fantasy systems alike. The converters are part of the Open Basing System and stack with the range’s own bases, movement trays and other converters, and they lift out again whenever the original base is wanted back.
- No glue, magnets or rebasing — the model drops in and lifts out, so converters are removable and reusable across the collection.
- Injection-moulded black ABS with a secure hold around the existing base.
- Textured top surface matches the rest of the range for a consistent look.
- Works with Open Basing System bases, movement trays and other converters.
- Available in packs from 1 to 100.
Compatible with popular tabletop miniatures; not affiliated with, endorsed by or produced by Games Workshop.
Notes · Q & A
Can a converter change my base footprint without rebasing?
OBS converters are designed to adapt an existing base where the selected conversion route fits that original footprint. Fit is route-specific, so confirm the selected option and technical drawing before ordering. Check Technical Specifications where added height matters.
How do I choose the correct converter?
Start with the footprint you already have, then select the target footprint you need. Compare both the accepted inner fit and the outer footprint with the technical drawing; matching nominal labels alone is not enough.
How should I use the technical drawing?
Choose your option first, then use the technical drawing and Technical Specifications to check the physical dimensions of the product. When matching an existing part or accessory, use the drawing rather than relying on the product name alone.
Can I rely on the nominal size alone?
No. Products with similar nominal sizes can have different physical dimensions or fit differently across brands and systems. Check the technical drawing, specifications and any product-specific compatibility note before ordering.
