Backing Plate Washer

[dschribs]

I just received the Griots 5“ backing plate for my G9.

It came w a "fiber" type washer on the stud of the backing plate.

Do I leave it on the stud when I mount the backing plate to the G9?

If so, what is the purpose of the washer?

Thanks!

Yep, whatever backing plate you have installed should have that washer in place. (You`ll notice the installed 6" one has one in place too).

I swear that washer came up in one of the videos, but I think preventing heat transfer was one of the functions. My GG6 stock plate and 5" plate had the washer as well.
