This part is discontinued and is no longer available.
However, for part AS47128: G1626222 is a potential alternative. The roller keeps will need to be repositioned.
For part AS47145: AS470445 is a potential alternative. Same product but without deadbolt.
Part ECO4R45 is also a potential alternative. This is a similar size lock but the roller keeps will need to be repositioned. If offset handles have been used, they will need to be replaced with inline handles.
