Universal chimney cap?

[shredit]

Moved into a very old house. There is a brick chimney with a 6 inch pipe inside. It stubs out of the stop of the chimney about a foot. I've been calling around trying to find a cap and all the places near me say they need to know the brand of the pipe to get the right cap. I have no idea what the brand is or how to tell without there being some kind of marking. Shirley somebody makes a cap that can be used on many different stove pipes? Maybe a clamp on? I'm living in a rental, will be here 5 years at the absolute most. Stove is a blaze king princess if that makes a difference

The stove is probably not important.
What IS important is what you have at the top of your
chimney & whether or not that installation is correct.
Can you post a pic so we can see what you have?

Here it is. Looks like stainless, single wall. There are no markings on it.

You are correct in thinking brand really doesn’t matter. You just need a rigid liner cap. It should be crimped and just slide into your existing pipe. No biggie

Yeah it doesnt matter what brand any rigid cap will work infact most flex caps will work to
