DH window lock

Hello, thank you for posting,

Unfortunately we cannot identify the brand of window from the sash lock shown. We should be able to assist with a similar replacement, but to further review, are you able to provide the distance between the installation holes from center to center? From there we can compare to our selection. Thank you! 

Thank you,

Please start by reviewing the style of the 90-161 lock and keeper set or the 90-077A lock that is compatible with the 90-177 keeper. Compare the dimensions to see if one of these could fit your sash. Let us know if you have any additional questions!
