Why You’ll Want This in Your Shop 🪚

Whether you’re building epoxy tables, charcuterie boards, or cutting slabs for custom furniture, a slab flattening jig is one of the most essential shop tools you can own. It turns your router into a precision planer, helping you flatten wide, irregular pieces that won’t fit through a jointer or planer.

The Rockler Slab Flattening Jig system is built for accuracy, control, and ease of use. With its rigid aluminum railsand smooth-gliding router carriage, it lets you produce flat, consistent surfaces every time. It’s especially useful for small shop setups where space or budget limits larger machines.

Whether you choose the mid-size or full-size version, you’ll be getting professional-grade results without the pro-level price tag — and the current sale makes it an even better value. 💪
