I’m thinking about refitting my current router table with a new router lifting device (my current one requires awkward motions under and at the rear of the table) but am unsure if all router tables have the same size opening for the insert to drop into.

The one on my current table (Craftsman) measures 9” front to back and 11 3/8” side to side. Are there other sizes out there, and do I need to “match” a lifter to my table?

Thanks, fellow LJ’ers.

Either that or make the opening fit the new router plate. I do believe that there are several sizes available in router plates.

Bondo is right; there are several different sizes available. To make it even more confusing, many (most?) lifts have attached plates that may or may not fit your existing hole.

I’d say research the different lifts to find what you want and make note of the plate size. You can always make an opening bigger to accept a plate.

Thanks for the prompt replies, folks. I should have added that my current router tabletop is made of machined aluminum, so altering the size on it is not practical. Looks like my best bet is to double check the size of the insert plate that comes with the ones I am considering.

I appreciate the feedback!

I have altered the size of insert plate to fit my table, most of them are aluminum and can be cut with a
good metal cutting skil saw blade in a table saw, of course this only works if the plate is bigger than
your opening.

There are two sizes that will be pretty easy to find lifts for and a bunch of other ones that will be harder. For instance Jessem lists two parts for it’s lifts.


I have a MLCS cast iron router table extension that I didn’t realize when I bought it but the plate opening is 9-1/32” x 12-3/32” which means the only lift I can use in it is MLCS’s. I was thinking about the idea of buying a lift for a smaller plate and trying to move it to a blank plate of the right size but the idea of taking apart a brand new several hundred dollar lift and trying to fit it to a blank plate doesn’t really appeal to me.

One thing you might want to consider if you really want to keep the router table is to buy a router with a built in above table adjuster like the Triton and just forgo the lift.

Best of luck.

Get the lift and router you want.

Tables are easy to make that are far more flexible in lift and fence compatibility.

Besides length and width differences, there are also two “standards” for thickness that have been used—1/4” and 3/8”. I have an older Rockler table, and the plates measure 8”X11”, and are 1/4” thick aluminum. Fine for my older medium-sized routers, but inadequate for a heavy-duty router—both in size, and thickness. I just would not trust 1/4” thickness for heavy-duty routers. I would have to probably do some digging to find a lift if I wanted to add one to my table, but figure my current table is fine for most tasks I throw at it. Someday I’ll likely just add a 2nd router table to the shop for use with a big Milwaukee motor and lift. My problem is I see features from Woodpecker, Jessum, Incra, and Kreg that I like, bit nobody has everything. I am most intrigued by the Incra system that uses the LS positioner.

Good luck with your hunt!
