Atrium door lock

Thanks for reaching out! Your handle set looks like it could possibly be replaced with our 82-400. I cannot guarantee that this will work as a replacement however, this appears to be the closest match we have to your existing hardware. Look over the dimensions and compare them to your existing handle and mortise lock set to confirm that this might work as a replacement for you.
