Rockler Bench Dog® ProMAX Cast Router Table without Plate (40-102)

Use your table saw as a base for this cast iron router table top! Saves lots of space, and uses one of the most sturdy anchors in your shop to cut vibration and noise. Great for combining with router lifts.
Item #
92% of 100

Expand your table saw's versatility by adding this industrial grade router table in place of the extension wing. Perfect for shops where space is tight, ProMAX includes a cast-iron top, Bench Dog's 28" ProFence, a miter gauge track that adjusts for a no-slop fit. If workspace is an issue, the ProMAX has you covered. Its dual fence slot configuration lets you rotate the fence and work from either side of the table to maximize surface area. Plus, with a third miter slot at its disposal, your table saw becomes perfectly equipped to handle crosscut sleds.

Your table saw needs to be 27” deep and 1-1/2” thick to work with the Rockler Bench Dog® ProMAX Cast Router Table. The holes on the Promax should match at least three holes on your saw or you may need to drill additional holes in the Promax table. The ProMax mounting hole pattern can be found under Technical Downloads.

Notice: ProMAX cannot be installed as a left extension replacement on left tilt ""cabinet"" grade table saws because the table saw's motor protrudes to the left. Nor can ProMAX be installed as a right extension replacement on right tilt ""cabinet"" grade table saws for the same reason. Mounting ProMAX to the far right will avoid the protruding motors, however, ProMAX must be supported with two steel rails that also support your T-square style rip fence and legs.

Heavy and solid, makes my contractor saw much more stable and smooth. You need two persons to install, one to hold it in position and another to attach the bolts. Be sure you know your router insert dimensions before ordering or what lift you are going to use to make sure the router lift and the saw extension fit together.

A nice product that will do the job.
The 3-hole pattern on router table did not match the pattern on my Delta 36-5000 Table Saw. Tapping and drilling the table saw at the pattern of the router table solved the problem without a lot of difficulty.

Promax benchdog router table
Had a coupon and decided it was time to get a real router table. I chose the Bench Dog Promax as I have limited space and this table exactly fits my table saw. It arrived surprisingly ahead of schedule, well packed, and with instruction. I was able to install it by myself as I have a adjustable hydraulic table. The table is rock solid, came with a fence and hardware. I am very satisfied with this purchase.

Bench Dog Cast Iron router insert.
I had seen where it fits on the Rigid model cabinet/table saw like the one I have. And it did with no real effort. Was even able to reinstall the steel wing removed to install this cast iron insert. And the router lift I picked out fit perfectly. This is an awesome addition and would recommend it to anyone even thinking about this kind of upgrade.

Big, heavy, worth every penny
I installed the cast iron Benchdog extension on the right side of my Grizzly 0390. I then added the Incra Master Lift II R. What a combination! I'm thoroughly pleased with both the Benchdog extension and the Incra lift.

Perfect for my needs
I had been wanting to build a bad a ss ed router table as an extension to my table saw for a long time. After TONS of research and pricing ect, this is what I went with. Its the best solution for space saving, adds mass to the table saw which helps to ground it and run smoother. This thing is heavy. Install was pretty easy outside of the weight issue. I paired it up with the Jessem/Incra Lift system also sold by Rockler and put a 3 1/4hp Porter Cable motor in it. The fence is good but I will be upgrading at some point. I am a very happy camper with this set-up.

This is a well designed router table. Extremely durable and fits most table saws, or at least it fit mine. This router table is a real asset when it comes to getting it right the first time, and for longer pieces of wood.<br /><br />I love it.

I added this router table as an extension wing to my table saw. This is my second router table from Rockler, and this one is now used as the primary router table in the shop. Both tables are from Rockler, and each is fitted up with the same lift and router motor.

Need a solid base for router
Dennis R on Oct 28, 2016
I have wanted this table, which attaches to my saw, for some time. This space saving table doubling as a table saw wing is also cast iron which I expect to reduce vibration, increase stability and provide a fairly large routing platform. It comes with a nice fence.

does this table include the fence?
Paul M on Dec 7, 2017
BEST ANSWER: I purchased this table to install on an older Craftsman saw table.
All the pieces fit very well
It did come with a very good fence with vacuum attach point
The fence was a solid fence.
The table included hanging hooks underneath to store the fence out of way.
Will this fit a Delta UniSaw (left of blade) without the router (Hitachi) interfering with the saw's bevel handle?
Ed B on Oct 2, 2015
BEST ANSWER: I attached my table to a higher end craftsman table saw and I use the craftsman routers with it. The combination of all three has worked out perfectly for what I do.
Richard B on Dec 27, 2015
BEST ANSWER: If you have front and back angle iron supports for a "T" style fence system that extend at least half the width of the router extension, you should be ok. You can drill a hole though the fence and extension table and bolt the table to the fence to keep the table from drooping and keep it even with the saw table. If you don't have angle iron supports or can't add any, then I would go with legs.
I have a newly purchased Rikon 10" table saw model #10-201 w/ 271/2 between the rails. Will this fit, & does it fit on the right or left as you face the saw?
John P Clarke J on Dec 21, 2016
BEST ANSWER: I fit it onto a Sawstop saw, not a Rikon. It fit perfectly, on the right side of the saw, but it would have also fit on the left, as the holes for attachment were symmetrical.
Will this fit a ridgid r4512?
Johnn on Dec 18, 2016
BEST ANSWER: Yes, I mounted it on the left side of the R4512, although you can mount it on the right as well. They say you can’t mount it on the left, because of the motor bulge on these left-tilting blade saws, although all you have to do is remove the motor access panel and tilt the blade out of the way which lifts the motor out of the way and there are some holes that are wide enough that you can get in there with a wreck and tighten the center bolt up just fine. Much easier if you flip the entire saw upside down in my opinion, but you don’t have to.
Will this table plate fit a Dewalt 746 table saw? If so, will we have to drill holes, or will the plate aling with the OEM holes in the saw? Thank you!
Emile M on Apr 22, 2016
BEST ANSWER: Measure your table and match to the dimensions of this item. I had to drill doles in my fence rail.
Is this ok for use as an extension in delta table saw?
eloy R on Jun 9, 2018
BEST ANSWER: The router extension I purchase from Rockler is a Bench Dog. I installed it on my Rockwell Unisaw and it fit perfectly. It gives me a very stable router location and does not in any interfere with the saw operation. I would think that it would do the same for your Delta saw. Actually, I think the item description for this extension specifies the saws it will fit. Good luck with this!!
How do you maintain the cast iron Bench Dog router table top to prevent and/or remove rust?
Rodger on Jan 5, 2018
BEST ANSWER: I treat it the same way I treat my table saw. I use paste wax a couple of times a year. I do not let eather rust. If you do have some Rudy, I recommend 00ste wool and oil. Just put oil on the table and rub it with the steel.
Does the fence adjust for jointing?
Randyryang on May 8, 2017
BEST ANSWER: The fence sides can't be easily offset for jointing. You might be able to add a shim to one side to allow for this. I never tried it as I have a 6 inch jointer.
I have a Delta table saw model 36-725. I'm a bit confused as to which extension this table would replace - the right or left (view from the cutting position)? I'm also curious if it will actually fit this Delta model. Lastly - I'm assuming I will still need (in addition to the router lift) an on/off switch, yes??
Tom on Mar 4, 2016
BEST ANSWER: It replaces the right extension. As for on/off switch, I just reach underneath and switch on and off the router right on the unit itself. You can certainly get a third party on/off switch or speed control, etc, but not necessary.
Does Milwaukee 5650 work with router table extension?
Clark K on Aug 24, 2019
BEST ANSWER: This wind doesn’t include a router plate, so your router compatibility would depend on the one you selected... I would urge you to consider a router lift however, I’ve found it so very much ore convenient than a stationary router plate
I am considering the Bench Dog cast iron router table extension for my Older Rigid R3612 table saw. I have 2 questions. Does this mount on the right side? Also, which plate do you recommend fir my Triton TRA001? Thanks.
PianoManNY on Aug 11, 2019
BEST ANSWER: I am using a Saw Stop saw and it is mounted on the left. I attempted to mount it on the right, however, it interfered with the blade tilt which tilts left. Most blades tilt right ( SawStop is opposite ) so your only choice may be a right mount. I used the Rockler plate with a Bosch router and have been very pleased. I would do a temporary install and see if you have clearance before permanent mounting.
Will the Rockler Bench Dog router table extension work with a Bosch 4100 table saw?
Gib B on Dec 20, 2017
BEST ANSWER: I do not know as I installed my router table extension on my SawStop table saw. BTW I love having both tools sharing the extended cast iron table.
What is the measurement from the back side of the extension (side that attaches to the table saw) to the edge of the router plate?
Bryce on Nov 29, 2017
BEST ANSWER: Dear Bryce,
The near edge is 3 3/4" and the far edge is 12" from the edge of the table saw. For the record it is an incredible piece of equipment.
I just bought the Laguna Fusion table saw from Rockler and I'm interested in adding this Bench Dog cast iron router table to the right side of the Laguna. Am I good to go?
Seth M on Mar 14, 2017
BEST ANSWER: I mounted mine on a older Craftsman floor model. The holes in the Bench Dog did not match up, but I was able to drill new ones in the Craftsman table. Otherwise everything worked fine.
Will this fit a Powermatic PM1000 table saw? If so is it a direct bolt on or will I need to drill holes through the cast iron? Is it difficult to install? Thanks.
DLMCJR on Feb 12, 2017
BEST ANSWER: I installed this router table on a shop fox 1819. The installation was pretty much straight forward but I did need to drill two holes in the rails, but not in any cast iron. One tip, get some help to install this as it is very heavy. I absolutely love the table. The fence is great, an all accessories at top notch. Sorry I cannot help further.

Is there any way to mount a dust collection box underneath (around the router), like the Incra Cleansweep or something homemade? Looking at the pictures in the manual, it looks like it would be difficult, if not I impossible.
Chris W on Jan 24, 2017
BEST ANSWER: You probably could. There are four holes near the corners, two are in front for the hooks to hang the router fence but there are two more in back. You could make a box with an lip with holes in the front and still mount the hooks and use the nuts with them to secure the box lip. There are also multiple holes beneath the router plate to level the plate, you probably don't need to use all of them to level it so a couple could be used to mount a box.
I am interested in purchasing the rockler bench dog pro max router table 40-102 for my Shop Fox 1824 table saw. My question is will it work with an install on the right side of my saw?
Mike B on Jan 10, 2017
BEST ANSWER: I installed the table on the right side of my Craftsman (RH when facing the saw) after I removed the composite wing on that end. Some of the holes in the router table did not match with the holes on the metal part of the saw table but I was able to drill new holes in the Craftsmans iron top and mount the table. Everything has worked fine and provides a nice stable surface for the router. I also purchased a lift and router with the table so everything works together Hope this helps.

does the bench dog router table for table saw come with mitre fence?
Ken on Dec 17, 2015
BEST ANSWER: It comes with the Bench Dog fence shown in the picture. Very high quality adjustable fence with dust collection port.
Will this fit sawstop contractor table saw?
david t on Feb 10, 2020
BEST ANSWER: I've added it to a Delta 10" tilting arbor saw which is a heavy duty contractors saw with a wide base and counter balanced it with a cast iron wing on the opposite side. It is heavy, especially if you use a large router and would need a counter balance or additional legs if you have a sheet metal table on the opposite side.
Will this fit my ridged R 4512?

Nunzio R on Mar 14, 2019
BEST ANSWER: Sorry, I have no idea. Mine is installed on a Jet saw table on the end.
Will it mount directly to cast table on right side of rigid 4512?
Cory S on Mar 9, 2019
BEST ANSWER: while I have not done it yet that is the reason I bought it.
I have the 4512 table saw and the bench dog router top. Just haven't had time to put them together.
The reason I did buy both is because of a Youtube video that I was were someone did exactly that.
Below is the youtube link that will show you how it's done.
There's a youtube video that shows it being attached but they won't let me put it here.
