replacement handle for Chamberdoor

I'm afraid I'm not familiar with that brand name. Can you show me a picture of the handle in question? That will help us find a match.

I think I can help! This is an old Emtek 322 lock set. This exact set isn't available anymore, but in the past I've been able to replace it with the 40-049. I found that this was a pretty good replacement that caused me very little trouble during installing. Look at the related video and see what you think!
