I cut a small X pattern in the middle to run my 2 tent stove chimney pipe thru. Reading reviews on other tent stove jacks, the common problem was tearing. This one is made with sturdy material and when I pulled on cut section (about 10-15lb force) it didn't tear.
We needed a damper to help regulate our wood stove and this does the trick. It's working wonderfully and we have no complaints so far! Now if we can only find someone who wants to chop and stack our wood...
It felt way more heavy duty then the ones I’ve bought locally. Hope it lasts.
