what are these sash locks?

Thanks for reaching out to us! Your CDI window lock looks like it can be replaced with either our 90-274 Acorn Lock and Keeper or our 90-278 Lock & Keeper. To determine if either of will be a fit for your repairs, carefully compare their dimensions.

Dimensions for 90-274

Dimensions for 90-278

Neither of the keepers sold with these locks would install the same way your existing keeper would, so you may need something like our 90-282 Recessed Keeper. Take a look over the dimensions to see if it could work for you.
