5 inch Backing Plates on Meguiar's, Griot's and Porter Cable DA Polishers

5 inch Backing Plates on Meguiar's, Griot's and Porter Cable DA Polishers


Here's some pictures showing the size of different backing plates on the popular Meguiar's Griot's and Porter Cable DA Polishers.

The Griot's and Meguiar's DA Polishers come with 6" backing plates and the Porter Cable by itself does not come with a backing plate.

If you want to use 5.5" foam pads on any of these tools you'll need to remember to order a separate backing plate when your order your polishers.


From left to right...

Factory Griot's 6" BP, Lake Country 5" BP, Meguiar's 5" BP and 5" Black Heavy Duty BP



5" Lake Country held against 6" Griot's Garage Backing Plate for size reference



5" Lake Country Backing Plate on 6" Griot's Backing Plate for size reference



Griot's measures just under 6"



Griot's measures approximately 5 3/4"



Lake Country measures just under 5"



Meguiar's W67DA measures just under 5"



Heavy Duty Black DA Backing plate measures just under 5"



Griot's 6" backing plate too large to safely use with 5.5" foam buffing pads



Backing plate overhangs past foam pad






See the little rubber cap?
It holds the compression washer on the threaded stud and also protects the threads when the backing plate is not in use. Do not loose it and if you do you can simply wrap some tape around the threads while backing plate is in storage.




This is a Compression Washer - Don't lose it and don't use any backing plate without it.




Meguiar's G110v2 comes with the W68DA Backing plate, it's too large to safely use with a 5.5" foam buffing pad.



Meguiar's W67DA Backing plate placed on top of the W68DA Backing plate for size reference



With a 5.5" foam buffing pad attached you can see the overhang of the W68DA Backing Plate



The Meguiar's W68DA Backing plate measures just under 6" in diameter

G220v.1 & v.2 comes with 5" b/plate.

If you loose it, (actually BEFORE you loose it) take a look at your local hardware store plumbing department. These are a fiber washer and are use commonly in the plumbing trade.

Coat...50 cents or so.

Good information to know for people that live outside the U.S. My guess is some countries don't want to import the 7" Softbuff pads especially if they already import the 6" pads that have been around since the 1970's

Great point Bill.

I'll try to take a picture of the damage caused by not using the compression washer today and add it to this thread.

Like Marc said, "yes" the Megs backing plate will work with your PC7424


Lots of people never add the letters XP at the end of 7424 so I never know for sure if they have a first generation Porter Cable 7424 or a second generation Porter Cable 7424XP but in case you do have a first gen, be sure to read this article,

All of the popular DA Polishers, old and new can use backing plates with the 5/16" threaded stud for attachment to the spindle.



Threaded stud in picture below is 5/16 and common to all popular DA polishers

Hello Mike, Pre ordered the Groits DA I have a couple questions for you. I want to go with 5.5" lake country pads and also will be using the Meg Microfiber system which backing plate would I buy? Can I use the same backing plate for regular LC pads and Meg Microfiber system? I am debating on adding the larger/longer cord is this nessasary? What advantage does it have? Advise from some other member out there would also be greatly appreciated thanks everyone.
