How to Attach a Multi-Track Fence to a DeWalt Table Saw

A “multi-track” fence is just a fence face with T-slots built into it, so you can slide on featherboards, stop blocks, and sacrificial faces instead of clamping everything on. DeWalt’s jobsite saws, including the DW745, DWE7480, DWE7485, DWE7491, DWE7491RS and DWE7492, don’t come with this feature from the factory. You can add it two ways: buy a purpose-made replacement fence built for your exact model, which bolts onto DeWalt’s existing mounting points with no drilling, or attach a T-track bar or shop-made wood fence to the fence you already have. Either way, the same core steps apply: remove the stock fence face, mount the new track, check that it’s parallel to the blade, and reset your rip scale, since adding any fence face changes what the pointer reads.

What a Multi-Track Fence Actually Is

“Multi-track” isn’t a brand name, it’s a generic term for a fence with more than one T-slot, or “track,” cut into it. Each slot accepts a T-bolt or T-nut that slides along the length of the fence and locks wherever you need it. That lets you mount a featherboard to hold stock against the table, a stop block for repeat cuts, or a sacrificial wood face, all without reaching for a clamp every time. A single track down the top of the fence is common on budget upgrades; two or three tracks, on the face and the top, give you more places to mount things at once.

DeWalt’s jobsite saws ship with a plain aluminum or steel fence face and no built-in track, which is normal for this category of saw. Adding track is a well-known upgrade in the jobsite-saw community, and there are two realistic ways to do it.

Two Ways to Do This

	Purpose-built replacement fence	DIY track or auxiliary fence
What it is	A fence body made for your exact DeWalt model, with T-slots already built in	A separate T-track bar or shop-made wood fence you attach to the fence you already have
Drilling required	Usually none. It bolts to the same points as the factory fence	Some. You’ll drill and/or tap the face of your existing fence, or build a wood fence that clamps or screws to it
Cost	Roughly $150 to $250 depending on model and options	Roughly $20 to $60 for a track bar, or just scrap plywood and a track insert
Best for	Anyone who wants a clean, tested fit with no guesswork	Anyone on a budget, or who wants a fully custom fence

Option A: A Purpose-Built Replacement Fence

Companies that specialize in jobsite saw accessories, such as TSO Products, sell a complete replacement fence body machined with T-slots, designed to bolt directly onto your DeWalt saw’s existing rail and bracket system. You keep the factory rails and the rack-and-pinion adjustment mechanism, you just swap the fence itself. These are sold separately for DeWalt’s compact saws (DWE7480, DWE7485, DCS7485) and full-size saws (DWE7491, DWE7491RS, DWE7492), since the mounting points differ between the two, so buy the version listed for your specific model.

This is the simpler route if you want a clean result without cutting anything or second-guessing whether your DIY measurements are right. It costs more than a DIY track, but the installation is largely bolt-on, since it’s designed to reuse DeWalt’s original mounting hardware.

Option B: DIY Track or a Shop-Made Auxiliary Fence

If you’d rather build it yourself, there are two common approaches. The first is buying a short aluminum T-track bar, sold by several woodworking brands, and mounting it directly to the face or top of your existing DeWalt fence with screws or bolts. The second is building a simple plywood or MDF auxiliary fence, sized to fit snugly over your stock fence, with a track embedded in its face or top edge. Woodworkers on forums like Fine Woodworking and LumberJocks have built both versions successfully on DeWalt jobsite saws for many years, so this is a well-tested path, not a workaround.

What You’ll Need

• Your chosen fence upgrade: either a replacement fence made for your model, or a T-track bar plus mounting hardware
• A drill and bits sized to your screws or bolts
• A tap and die set, if you plan to thread holes directly into a metal fence face rather than using a nut on the back side
• A combination square or engineer’s square, to check the fence is parallel to the blade and square to the table
• A tape measure
• Clamps, to hold everything in place while you drill and test-fit
• Your saw’s manual, so you can identify the exact mounting points for your model before you remove anything

Installation Steps

Step 1: Prep the Saw

1. Unplug the saw. You’ll be working with tools right next to the blade area.
2. Remove the stock fence. Loosen the locking lever and slide the fence off the front and rear rails. Installing a replacement fence kit? Check its instructions first, some ask you to reuse the old fence’s mounting brackets.
3. Measure your existing fence. Note its height, length, and any screw holes. This is your reference if you’re building a DIY wood auxiliary fence.

Step 2: Mount the Track

1. Attach the new fence or track. A replacement fence bolts straight onto the saw’s rail system, the T-slots are already built in. For a DIY track bar, mark and drill your hole locations, then tap the holes for machine screws, or drill through and back it with a nut, countersunk flush. On wood, pilot-drill and use wood screws or T-nuts.
2. Set the height. Leave a small gap, about 1/16 to 1/8 inch, between the track and the table. Too low and it drags; too high and dust wedges underneath.

Step 3: Check the Fit

1. Test the slide. Still unplugged, run the fence the full length of the rails. It should move smoothly with no dragging or binding.
2. Check parallel to the blade. Raise the blade fully. Measure blade-to-fence distance at the front and back, using the same tooth both times. The two numbers should match, adjust per your manual if not.

Step 4: Calibrate and Test Cut

1. Reset your rip scale. A new fence face shifts where the pointer’s zero point actually is. Rip a test piece against a tape measure, then recalibrate the pointer or order a replacement scale decal.
2. Check guard clearance. Slide the fence in close to the blade and confirm the new fence and hardware clear the blade guard, riving knife, and anti-kickback pawls. Notch a wood auxiliary face rather than letting it overhang the blade.
3. Reconnect and test cut. Plug the saw back in and make a few scrap rips before cutting anything real. Watch for drift, a sign you missed a parallelism issue.

Common Mistakes People Make

• Buying a replacement fence sized for the wrong DeWalt model, since compact and full-size saws use different mounting points
• Mounting the track too low, so it drags on the table every time the fence moves
• Skipping the parallel-to-blade check after installation, since a new fence face can shift alignment slightly even when everything looks square
• Forgetting to recalibrate or replace the rip scale, which leads to cutting workpieces to the wrong width the first time out
• Letting a wood auxiliary fence overhang the blade path without notching it, creating a pinch point during narrow rips
• Drilling into the fence without first checking for internal ribs or the locking mechanism hiding just behind the surface
• Not testing the slide motion before locking everything down permanently

Frequently Asked Questions

Will a multi-track fence fit any DeWalt table saw?

Not universally. Purpose-built replacement fences are sold separately for DeWalt’s compact saws (DWE7480, DWE7485, DCS7485) and full-size saws (DWE7491, DWE7491RS, DWE7492), since the mounting points differ. A DIY track bar or shop-made auxiliary fence is more flexible, since you’re sizing it to whatever fence you already have.

Do I need to drill into my DeWalt fence?

Only if you’re going the DIY route. A purpose-built replacement fence is designed to bolt onto the saw’s existing rail brackets, so it typically requires no drilling into the saw itself.

Does adding a fence face reduce my rip capacity?

Slightly, yes. Any auxiliary fence or track adds some thickness in front of your original fence face, which reduces your maximum rip width by roughly that same amount on that side.

Why does my rip scale read wrong after installing a new fence?

The factory rip scale is calibrated to the stock fence’s exact position. Any auxiliary fence or replacement fence changes where the true edge sits, so the existing pointer no longer lines up correctly until you recalibrate it or fit a new scale.

Can I use a wood auxiliary fence instead of buying aluminum track?

Yes, and it’s a common, well-documented approach. You can embed a short section of aluminum T-track into a plywood or MDF fence face, or simply drill mounting holes at set intervals if you don’t need sliding hardware.

Bottom Line

Adding a multi-track fence to a DeWalt jobsite saw is a well-worn upgrade, not an experimental one. If you want the simplest path, buy a replacement fence made for your exact model and bolt it onto the existing rails. If you’d rather build it yourself, a T-track bar or a shop-made wood auxiliary fence gets you the same functionality for less money. Whichever way you go, the steps that matter most are the same: mount the track clear of the table, confirm the fence stays parallel to the blade, check clearance around the guard, and reset your rip scale before you trust it on a real cut.
