Setting up your workshop for smooth, accurate cuts can be a challenge, especially when your needs go beyond what standard gear offers. If you own a DeWalt table saw and want more precise control, attaching a multi track fence can completely change your woodworking experience. Many hobbyists and professionals know that factory fences limit what you can do, especially for custom jigs and repetitive tasks. Adding a multi track fence lets you use stops, featherboards, and accessories that improve safety and accuracy.
But how do you properly attach a multi track fence to your DeWalt table saw? This is a question many users ask, and getting it right is not always simple. There are different fence systems, mounting methods, and adjustments you need to consider. In this guide, you’ll learn exactly how to choose, install, and use a multi track fence with your DeWalt table saw—step by step, with tips and advice you won’t find in the manual. By the end, you’ll feel confident upgrading your saw, avoiding common mistakes, and getting the most from your setup.
What Is A Multi Track Fence And Why Use One?
A multi track fence is a special type of fence for table saws and other woodworking machines. It has one or more T-slots or tracks along its length, so you can attach stops, clamps, hold-downs, or jigs. This makes your work much more flexible.
Benefits For Dewalt Table Saw Owners
- Greater accuracy: You can set repeatable stops for batch cuts.
- Improved safety: Attach featherboards to keep wood tight against the fence.
- More versatility: Use special jigs for dados, rabbets, and other cuts.
- Easy upgrades: Add new accessories without changing the whole fence.
Most DeWalt table saws, like the DW745 or DWE7491RS, come with a basic fence. While these are sturdy, they lack T-track slots for accessories. Upgrading to a multi track fence lets you do more complex work and improve your results.
Understanding Your Dewalt Table Saw Fence System
Before you begin, it’s important to know how your DeWalt fence system works. Not all fences or saw models are the same. Some have a rack-and-pinion system, while others use a more traditional sliding fence.
Common Dewalt Models And Their Fence Types
| Model | Fence Type | Mounting Style |
|---|---|---|
| DW745 | Rack & Pinion | Front & Rear Rails |
| DWE7485 | Rack & Pinion | Front & Rear Rails |
| DWE7491RS | Rack & Pinion | Front & Rear Rails |
| Older DeWalt 744 | Sliding Clamp | Single Side Mount |
The rack-and-pinion system uses gears and rails to move the fence smoothly and keep it parallel to the blade. This is both a benefit and a challenge: the fence stays square, but adding custom fences is harder.
Non-obvious insight: Many users try to bolt a new fence onto the existing DeWalt fence. However, this often leads to misalignment and lost accuracy. The better way is to attach the multi track fence as an add-on, using the existing fence as a base.
Choosing The Right Multi Track Fence
Not all multi track fences are equal. Some are designed for universal use, while others fit specific saws. Before buying, consider these factors:
Key Features To Look For
- Track size and compatibility: Most use standard 3/4″ x 3/8″ T-tracks, but check your accessories.
- Length: Should match or slightly exceed your saw’s table width for full support.
- Material: Aluminum fences are light and strong. Steel is heavier but more rigid.
- Mounting options: Some fences come with clamps or bolts, others require drilling.
Popular Multi Track Fence Brands
| Brand | Main Features | Approx. Price |
|---|---|---|
| Kreg | Multiple T-slots, easy mounting | $60–$150 |
| Incra | Micro-adjust, heavy-duty | $100–$250 |
| Rockler | Budget, expandable | $40–$100 |
| Powertec | Simple, universal | $30–$80 |
Non-obvious insight: Some users build their own multi track fences using aluminum T-track extrusions and plywood or MDF. This can save money and allow you to customize the size and slots.
Check For Compatibility
Measure your existing DeWalt fence’s height, width, and mounting holes. Most multi track fences will need to be attached on top or in front of the factory fence, not replace it.
Tools And Materials Needed
Gathering the right tools and materials before you start will make the process much smoother. Here’s what you’ll need:
- Multi track fence (purchased or homemade)
- Measuring tape and ruler
- Drill with drill bits (metal and wood)
- Screwdriver (Phillips and flathead)
- Clamps
- Bolts, washers, and nuts (usually 1/4″ or M6, depending on your fence)
- Hex keys/Allen wrenches
- Marker or pencil
- Safety glasses
- Vacuum or brush for cleanup
Optional but useful:
- Thread locker (to keep bolts from loosening)
- Double-sided tape (for temporary positioning)
- Carpenter’s square (for checking alignment)
Step-by-step: How To Attach A Multi Track Fence To Your Dewalt Table Saw
The following instructions work for most DeWalt models with a standard rack-and-pinion fence. If your saw is different, adapt the steps as needed.
1. Remove The Factory Fence (if Needed)
Most of the time, you will not remove the entire factory fence. Instead, you’ll attach the multi track fence to its face or top.
However, if your multi track fence is designed as a direct replacement, unlock the fence and slide it off the rails. Keep all hardware in a safe place.
2. Position The Multi Track Fence
Place the multi track fence on top of or in front of the DeWalt fence. Center it so it covers the full length of the saw table, and check that it does not block the blade or miter slots.
Tip: Use clamps or double-sided tape to hold the fence in place while you measure and mark.
3. Mark And Drill Mounting Holes
With the fence in position, use a marker to note where the mounting holes line up. Most users mount the new fence through the side or top of the factory fence.
- For an on-top mount, drill through the top of the DeWalt fence and the bottom of the multi track fence.
- For a side mount, drill through the face of the factory fence and back of the multi track fence.
Use a drill bit slightly larger than your bolts for some adjustment room.
4. Attach The Multi Track Fence
Insert bolts through the holes you drilled, add washers, and tighten the nuts on the other side. Do not overtighten—just enough to hold the fence snugly.
If your fence has slotted holes, you can fine-tune the alignment before fully tightening.
Important: Check that the fence moves freely and stays parallel to the blade. If it binds or tilts, loosen the bolts and readjust.
5. Check Alignment And Squareness
Use a carpenter’s square to check that the multi track fence is perfectly perpendicular to the saw table and parallel to the blade.
- If the fence is out of square, add shims (thin plastic or metal strips) between the fences before tightening.
- For parallel alignment, measure from the fence to the miter slot at the front and back—they should be equal.
6. Test The Fence Movement
Lock and unlock the fence several times. Slide it back and forth. It should move smoothly and lock solidly without play. If it sticks, check for bolts that are too long or tight.
Pro tip: On DeWalt rack-and-pinion fences, avoid blocking the gear track or clamp mechanism with bolts.
7. Attach Accessories And Test Cuts
Now add stops, featherboards, or other jigs to the multi track slots. Make a few test cuts with scrap wood to check for accuracy and safety.
If the fence shifts during use, double-check that all bolts are tight and the fence is fully seated against the factory fence.
Common Problems And How To Fix Them
Even careful users can run into issues. Here’s how to handle some of the most frequent problems:
Fence Not Parallel To Blade
If your cuts are burning or the fence feels “off,” measure the distance from the fence to the blade at both the front and back. Adjust the fence as described earlier, using shims or by loosening and retightening bolts.
Fence Flexes During Cuts
If you notice the fence flexing under pressure:
- Use more mounting bolts (minimum two, ideally three or four).
- Choose a stiffer fence material, like thick aluminum.
- Add a rear support block if your fence is very long.
Accessories Don’t Fit Track
Double-check the T-track size. Some brands use metric slots, which can be slightly different from US-standard tracks. You can buy track adapters or file down accessories for a snug fit.
Fence Interferes With Saw Functions
Make sure the fence does not block the blade height wheel, bevel lever, or dust port. If it does, move the fence up or back slightly, or trim the ends.

Tips For Better Results
- Always measure twice before drilling holes in your factory fence.
- Use thread locker on bolts if you plan to leave the fence in place long-term.
- Clean sawdust and debris from the fence and rails often; buildup can affect accuracy.
- For portable saws, choose a lightweight fence to avoid tipping.
- Label your accessories, so you know which fit each track.
- If you use dado blades, make sure the fence has enough clearance for the wider cut.
Safety Considerations
Upgrading your table saw can make it safer—but only if you use the fence correctly.
- Always lock the fence before cutting.
- Do not use damaged or bent fences.
- Add featherboards to keep hands away from the blade.
- Wear safety glasses and keep the area clear.
- Test the fence with scrap before real cuts.
Remember: a fence that shifts, flexes, or binds is dangerous. Fix any problems before cutting.

Maintenance And Long-term Care
A well-installed multi track fence should last for years, but it needs some care.
- Check bolts and nuts every few months for tightness.
- Lubricate sliding parts with dry lube (not oil or grease, which attract dust).
- Clean tracks and slots to keep accessories sliding smoothly.
- Inspect for bends, warping, or damage after accidental hits.
- Store accessories in a box or drawer to avoid loss.
When To Upgrade Or Replace
If your cuts are no longer accurate, or the fence is bent or worn, it’s time to consider a new fence or a better mounting method. Signs that you need an upgrade:
- Fence does not lock solidly
- Track slots are damaged or stripped
- Accessories no longer fit
- Fence is rusted or dented
In these cases, investing in a high-quality system (like Incra or Kreg) can save time and reduce frustration.

Real-world Example: Upgrading A Dewalt Dw745
Let’s look at how a typical user upgrades their DW745 with a Kreg multi track fence:
- The factory fence is left in place.
- The Kreg fence is placed on top, lined up with the blade.
- Two holes are drilled through both fences, spaced 8 inches apart.
- 1/4″ bolts and nuts attach the fences, with washers for extra grip.
- A featherboard and stop block are added in the T-track.
- The user checks squareness, tightens everything, and makes test cuts.
After setup, the user can repeat cuts quickly, add jigs for dados, and work more safely—all thanks to the upgrade.
Comparing Multi Track Fence Systems
Here’s a side-by-side look at three popular options for DeWalt saws:
| Fence System | Ease of Mounting | Accessory Support | Price | Best For |
|---|---|---|---|---|
| Kreg Precision | Easy (bolt-on) | Wide range | $$ | DIYers, pros |
| Incra LS Positioner | Moderate (requires drilling) | Excellent | $$$ | Advanced users |
