This product makes adjusting router height virtually effortless. Insert it through one hole in the table and unlock the clamp, them insert it through the other hole and adjust the height while watching the callibrated dial rotate on the table. Then return to the first hole to lock the clamp again. No need to crawl under the table and find the adjustment screws.

Porter Cable should advertise this item more. It provides a good alternative and simplifies use of the router table. I would not have known it was available if I had not done so much searching on the internet. It performs well and is very cost effective.

Compared to height adjustment systems that can sometimes cost hundreds of dollars, this is an incredible buy. It not only serves as a height adjustment tool, but has also made bit changing a breeze, without ever having to remove my PC 890 from the table. Like another reviewer, I wish Porter Cable would advertise this more, as I just happened to stumble upon it, during my research.

I use this device with a Rockler router table insert plate that replaces the Porter Cable factory base for the 980 series router. Rockler provides two holes in the aluminum insert plate that accommodate the height adjuster; one hole for the router lock clamp and one to adjust the height of the bit above the table. These holes line up precisely with the router's adjustment nuts. I get great accuracy and plenty of control with the large height adjuster handle. The micro-calibration washer that comes with the unit isn't very useful because of slight play in the router screw drive mechanism that adjusts the bit extension. I depend, instead, on a standard caliper to get the correct bit height.

I bought the P-C 891 Router and the P-C 698 Table, supposedly compatible. I ordered the 75301 Height Adjuster because it looked like a great help for adjusting the motor height from above. But there are no HOLES in the TABLE to pass this Adjuster through! The folks at Porter Cable admit they forgot to provide holes for the 890/891/892 router motor, and they are very nice about this, but told me yes, I really have to drill two holes in the table to use this gadget! The table comes with plenty of other holes to accomodate the attachments, motors, etc. so it seems a shame that they did not make two holes for the ht. adjuster. Actually it's not hard to reach underneath to open and close the locking lever and twist the original height adjuster. I just don't know if I want to drill out the table yet.

Item is great & works well! Problem is "PORTER CABLE" morals. They advertise automatic spindle lock & one wrench operation from above the router table. But, they forgot to mention the fact that they removed the auto-spindle lock because of a patent infringment! NICE COMPANY !!!!!!!!!

The tool turns the simple router base into a deluxe lift. Allowing for above table bit changes and precise height adjustment. It also came with an offset wrench to back up the collet to change the bit.

I bought this to use with the Porter Cable 891 router but I've heard this works on quite a few models. I have to say, a local woodworking shop tried to get me to buy their brand, glad I didn't. This Porter Cable option was the same price and works perfectly with the 891. Handle is easy to turn, you only need drill one small hole in your router table, and the bottom bell on this thing gives you a reference point to judge how much to turn it before measuring the exact height of your router on the table.

This adjuster as noted in other reviews is a great way to adjust the router from above the router table (providing the access holes are there, if not they will need to be drilled). The measurement ring is fairly useless but that should not be a problem as you should verify the hight needed for the project.

The second great advantage is the additional wrench for tightening/loosening the collet makes bit installation/removal a lot easier and safer than using the pin to hold the shaft stationary. I had the pin bend on the first router and then jam on the second router in the first day of use so the wrench was a life saver for me.
