Hey there,

Thanks for writing in! The ROTO casement locks you are searching for look a lot like either the 38-138 or 38-139.  They both have 3-7/8" installation holes measurements. 

To determine if either of these is the right replacement, carefully look over the dimensions below and compare them to the existing lock. These are only available in white.
