I need to replace several arm operators for Thermal gard windows in our home. The current arm operators are dual arm and have the word "Entry gard Truth" stamped on one of the arms with a # 20810. Are the Entrygard Dual arm operator #39-031 and #39-032 the correct replacement parts?

Thanks for posting! Based on the information given, I believe that the 39-032 & 39-031 may be what you're looking for. However, please make sure to match up the dimensions with your own hardware to be certain that they will match. Let me know what you find out!
