A descrete desk wheel chock for your Speed Champions builds. These will stop your cars rolling around on your desk and keep them still, even if you knock your desk.
This particular model will fit many Speed Champions that use the standard wheel mounting block. The interior space is 50mm. Speed Champions such as the Mclaren Solus GT will need a wider wheel chock, or as I have done for mine, cut the wheel chuck in half with some snips.
If you would prefer a dedicated width, please get in touch or drop a comment.
