My spelling doesn't look correct but I'm looking for the little rubber donut type thing that I could use for where my speaker wires pass into the bags. Stuff at the local hardware store seems better suited to sheet metal than the thick plastic of the bags..

 

I just ran speaker wires into my bags today. Drilled a 1/4" hole, pulled 16ga wire through, filled gap with black silicone. Putty will also work.

 

I found assorted grommets at my local Menards near the electronics install area near the heat shrink!
Worked in my saddle bags!

 

I did the same thing, silicone RTV holds them in place, and waterproofs.
The grommets wouldn't necessarily be waterproof...

 

Use properly sized grommets bro:

A proper job is worth the effort. Spelling helps with the Googling to find em.

Not cheap, but look nice.
