Introduction
The Kreg PRS1010 Precision Router Table Fence is Kreg’s innovative self-squaring T-square style router table fence. Based on the design of table saw fences, the Kreg PRS1010 is the only fence on the market that features a T-square design that allows for fast and easy positioning of the fence and a cam style lockdown which keeps it perfectly parallel to the miter slot at all times.
With most router table fences you adjust and lock down both sides of the fence independently which can make it difficult to keep the full length of the fence square to the table top and miter slot.
The Kreg PRS1010 is a totally different design, although anyone with a table saw will recognize the design – the fence slides smoothly on a track fixed parallel to the side of the tabletop. To adjust the fence all you need to do is release the cam lock, set your measurement on the scale using the magnified cursor and lock down the cam lock again which engages the opposite-side anchor to ensure incredible fence rigidity across the whole length.
Heavy-Duty Aluminum Design with Universal Mounting
The fence body itself measures 36-1/2” and is made of a fully enclosed heavy-duty aluminum extrusion – it’s typical Kreg high quality machining and is extremely rigid so that when the cam lock is locked down the whole fence is completely rigid along its whole length.
As with most fences, dust extraction is through the rear of the fence and the fact that the Kreg is fully enclosed at both ends helps create a vacuum chamber which improves dust extraction.
There is also an optional micro-adjuster available, the Kreg KMS7215 Micro-Adjuster which allows you to dial in precise adjustments one handed. It’s a simple design that works well and for $17 it’s worth investing in.
Compatibility with non-Kreg router tables
Luckily the benefits of this fence aren’t limited to woodworkers with a Kreg router table – the Kreg PRS1010 has a single-side universal mounting design which allows the fence to be used with most router table tops from 3/4” to 1-1/2” thick.
However, the lock-down knob on the left/outfeed side of the fence requires a slot to run in. Kreg router table tops obviously have a slot for this purpose, but if yours does not, you’ll have to cut an accurate slot in your table top and that may not be something you want to do in a $200-$300 phenolic table top.
You could not bother with the lock-down knob at all, but I wouldn’t recommend it as the lock-down is necessary to keep the fence rock solid at both ends. It’s a long fence and there’s no way it can remain steady if it’s only attached to the table at one end.
Comparison with standard fence adjustment methods
The standard router table fence adjustment system with two slots just doesn’t give you precise enough control over horizontal adjustment. Unless you’re using a fence like the Incra LS17, you have to measure by hand from both ends of the fence to the edge of the table, and you go back and forth from one end to the other until you get it square.
Perfect For Cross Grain and Mitering
The fact that the fence is always exactly parallel to the miter slot of your router table is particularly important for cross grain and mitering applications.
If you’re only putting a decorative profile along the edge of your workpiece, it doesn’t actually matter if the router table fence isn’t 100% square to the table top – it won’t affect the end result.
However if you are doing something more advanced that requires you to use the miter slot, like coping a rail for a door for example, it’s absolutely essential that the fence is parallel to the miter slot.
Independent Adjustable Fence Faces
The first benefit of a split fence is so that you can adjust for different cutter sizes. By adjusting the fence so that it is right up to the edge of the cutter (zero clearance) you get better support for the workpiece and minimize tearout.
The second benefit is you can shim the outfeed side of the fence to move it forward for edge-planing and full-face molding, effectively turning your router table into a vertical jointer. On the Kreg PRS1010 depth rods are stored inside of the fence and can be inserted behind the faces to allow for jointing depth adjustments of 1/16” and 1/32”. It’s quicker to set up than most fences that require you to remove the outfeed sub-fence to shim it.
What are the alternatives?
Nobody else makes a T-square style router table fence. The closest you’ll get is the JessEm 4010 Master Fence II which features a dual track fastening system that fits to the left and right sides of the table. It’s an improvement over twin slots cut into the table top, but you still have to adjust each end independently so you don’t have the same benefits as the Kreg PRS1010. It’s arguably easier to set up as you don’t need to cut any slots in your table top.
Bottom Line
If you want a self-squaring T-square style router table fence, it has to be the Kreg PRS1010 Precision Router Table Fence. Based on the design of table saw fences, the Kreg PRS1010 is the only fence on the market that’s got it, and if your router table is able to accommodate it, you get fast and easy positioning of the fence with a cam style lockdown that keeps it perfectly parallel to the miter slot at all times. You also get the option of fitting a micro-adjuster to give you a level of precision that you don’t get with anything short of the Incra LS17 Super System for a fraction of the price.
