EPI Window lock

A quick learner from Los Angeles says:
Hello, I am trying to identify which lock you sell would be a good replacement lock for my daughters window. I only have the picture I submitted and no measurements. Any help you can provide is appreciated. Thank you.

Hello, thank you for posting,

Please start by reviewing the style of the 90-278 or 90-274 locks. Compare the dimensions of each to confirm the best fit. You will need to use the original keeper, as the keepers that come with these locks will not work with your window. Let us know what you think and if you have any additional questions!
