Hi I have a client that is looking to replace some old non working actuators for their windows. Could not find any complete numbers on the arm. Found the name truth that is about it.

Hello, thank you for posting,

This operator resembles either the 39-438B and 39-439B or the 39-253LB and 39-253RB operators. The difference between these two styles is the guide at the end of the straight arm. Please review the video below that goes into more detail.

Also review the 39-451 and 39-452 or 39-375 and 39-376 cover/handles depending on style preference.

Please review and let us know if you have any additional questions!

Found a number on an arm AD0001 not sure if this will tell what set we will need.

Thank you.

Unfortunately we cannot cross reference the number provided. The original operator will need to be removed to confirm which style guide is used on the end of the long arm as shown in the video above. Please let me know if you have any additional questions.
