If you’re short on space or want to make the most out of your workshop setup, a router table extension for your table saw is one of the smartest upgrades you can make. These extensions fit into the table saw wing — usually replacing the right-side cast iron wing or mounting into a workstation frame — giving you a full-function router setup without taking up extra room.
Whether you’re routing dados, edge profiles, or joinery cuts, adding a router extension helps streamline your workflow and brings two major tools into one footprint. Below are the best router table extensions for table saws in 2024, with picks for commercial setups, garage shops, and hybrid saws.
1. Bench Dog Tools ProMax Cast Iron Router Table Extension (40-102)
This is the gold standard for router table extensions. The ProMax 40-102 is a full cast-iron top that replaces your table saw’s right-side wing. It’s rock-solid, dead flat, and fits most contractor and cabinet saws with little or no modification.
- 27″ x 16″ cast iron top
- Fits many Delta, RIDGID, Jet, Powermatic, and similar saws
- Pre-drilled for router lifts and plates (including Bench Dog, Kreg, Rockler)
- Fence sold separately
Price: $290–$320. If you want pro-level quality, this is it.
2. Kreg PRS1025 Router Table Top with Insert Plate
Don’t need cast iron? The Kreg PRS1025 is a high-pressure laminate router table top with a phenolic plate insert. It’s lighter, more affordable, and easy to adapt into shop-built table saw extensions or workstation benches.
- 24″ x 32″ MDF core top with edge banding
- Flat, rigid, and vibration-resistant
- Comes with Level-Loc insert plate (predrilled for common routers)
- Works well mounted to a DIY extension wing or cabinet
Cost: $180–$220. Excellent for hybrid saws or shop-built extensions.
3. Rockler Router Table Extension for Table Saws
Rockler’s steel-topped router table extension is designed for easy mounting on most contractor-style table saws. It includes a router plate, fence, and adjustable legs. If you’re looking for a complete kit that bolts into your existing frame, this is a practical, all-in-one solution.
- Fully assembled table with steel top and fence
- Measures 32″ x 16″
- Universal router plate included
- Comes with dust port and T-track fence
Price range: $270–$300. Great for users who want a bolt-on, ready-to-use system.
4. MLCS Cast Iron Router Table Top with Fence
MLCS offers a cast-iron router top that rivals Bench Dog but at a slightly more budget-friendly price. The surface is flat, the insert plate is solid, and it comes with a basic fence setup. A good option if you want the benefits of cast iron without the top-tier pricing.
- 16″ x 27″ surface
- Universal plate fits most fixed-base routers
- Includes aluminum fence with dust port
- Compatible with many contractor and cabinet saws
Expect to pay: $220–$250. A heavy-duty choice with great build quality.
5. SawStop RT-TGP Assembly with Cast Iron Table
If you own a SawStop cabinet or professional table saw, the RT-TGP extension is a factory-grade router table wing. It includes a cast-iron surface, router lift support, and full adjustability. You can mount it in place of the right extension wing or even in-line with the outfeed.
- 27″ x 16″ cast iron wing
- Includes fence and router plate (optional lift available)
- Fits perfectly into SawStop models
Cost: $350–$400. Premium fit, finish, and performance for SawStop users.
Key Considerations When Choosing a Router Table Extension
- Material: Cast iron provides the most stability and dead-flat accuracy. Laminate tops are lighter and easier to DIY mount.
- Compatibility: Make sure the extension matches the bolt pattern or frame size of your saw. Universal tables can often be drilled as needed.
- Router Plate: Check if your router fits the included plate. Many plates are pre-drilled for common models from Bosch, DeWalt, and Porter-Cable.
- Fence System: Some kits come with a fence; others require you to use your table saw fence or buy a standalone router fence.
- Dust Collection: Look for a port built into the fence or table body for better cleanup and airflow.
Accessories That Help
- Router lift for precise bit height adjustments
- Featherboards for safety and consistent pressure
- T-track stops for repeatable cuts
Final Thoughts
Combining a router table with your table saw setup is one of the best ways to save space and get more out of your shop. Whether you go with a full cast-iron wing like the Bench Dog ProMax or a flexible top like the Kreg PRS1025, the added versatility is hard to beat.
For a plug-and-play upgrade, consider the Rockler steel router extension. For long-term precision work, the Bench Dog or SawStop cast iron kits are built to last a lifetime. Either way, you’re making your saw smarter — and your shop more efficient.
