Class A Connection

[Greg123]

So the other day I noticed (Might have always been there) what seemed like a small separation in my class A, The pictures below are of the horizontal Class a coming thru the Wall Thimble and attaching the outside Tee.

The separation is only at the top, (1st Picture) around the bottom its and sides its fine no separation at all (2nd Picture) .

I also took off the cap of the tee and felt the inside where the seem is and couldn’t feel any separation from the inside at all with my fingers.

Just want other’s opinions on weather this is OK.

Thanks

looks like metal bestos, it screws together, but does come with locking bands as well

If the separation is only at the top, then the weight of
everything above the tee probably caused what you're seeing.
Make sure all your wall supports are tight.
Maybe even support the bottom of the tee,
loosen the supports, see if you can jack the tee up enough to
close the gap & THEN tighten all your wall supports.
