My tbh is a mess! AHHH!

The 2 bars you can see in the upper left corner are likely what he's talking about, or at least similar.



As for the barb idea, I don't think it will work. In fact, I suspect that it will actually make the attachment weaker.

"barbed top bar might not work"........
it was a thought. I'm too new a newbie on how the comb is actually attached and the bees been doing it for millions of years so I'll just leave it up to them!

Better is up to the owner.  I don't think the bees care.

Square was easier to build for me.
I could mix with lang deep if I wanted.

I do think the sloped ones are more attractive for a backyard setting.

I don't have a problem with the bees attaching to the sides, although you will hear that concern.

doug, I'm wondering about your experience with this square TBH.  How durable do you find the comb when under manipulation?  can you handle them just the same as the trapezoidal shaped ones?

Here is a YouTube video on fixing cross-combing:

but truly - prevention is the better answer.

Inspect gently, early, regularly, and thoroughly... bar by bar.

Be a good wax shepherd!
