Feeling the Heat
This was the thimble I used. https://www.northlineexpress.com/6-duratech-wall-thimble-6dt-wt-7059.html
There was still a bit of a gap so I just used a cheap cover to slip on and cover that small gap.
Good luck with your install!
Thank you!
So is it just double wall running through the thimble? Or do you have to get an adaptor and transition over to class A where it hits the thimble?
