🔍 It depends on the model. The SpeTool Cratos S01001 PRO router sled has a **maximum cutting width of 48 inches** (4 feet):contentReference[oaicite:20]{index=20}, which covers a very large slab. In terms of length, the sled can theoretically flatten any length because you can move the sled along the slab (often called “unlimited length” capacity):contentReference[oaicite:21]{index=21}. In practice, you might reposition the sled or slab for extremely long pieces. SpeTool’s larger Xpert S03001 sled is expandable with extension rails, so it can handle even bigger projects if needed. But as a baseline: about 4 feet wide and pretty much any length (by moving the setup) are achievable. Always ensure your support table or base is big enough to support the slab securely while flattening.
