03 OBS FAQs
Can I add magnets underneath OBS bases?
Check the selected option's underside opening and available underside depth in Technical Specifications before choosing magnets. Magnet fit depends on the actual cavity dimensions and the magnet you plan to use, so it should not be assumed to be the same across every base.
How do I choose the right base size?
Start with the base footprint required for your model or game, then confirm the selected option against the Technical Specifications. If you are replacing an existing base, measure it carefully and compare its physical footprint before ordering.
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.
