I need a replacement of this style

Thanks for posting! We do not carry an exact replacement for your existing handle set but our 82-005 may be worth considering as a replacement. This is a surface mount handle and does not require an internal mortise lock. To determine if this is the right replacement carefully look over the dimensions.

Also, take a look at the video below for an idea of how to install this handle set. See if this might work for you.
