Hello, thank you for posting! 

Your pivot bar resembles our 26-318 . Please compare dimensions for a good match. For the tilt latches, please compare the dimensions of our 26-243 and 26-244 . Before I can make a recommendation for the lock, are you able to confirm the measurement between the installation holes? Thank you!
