Hello,

Take a look and compare the specifications of the 39-031 and 39-032 EntryGard operators to yours, paying close attention to the length of the link arm. Please note that the link arm also has a downward offset, while yours appears to be upward. Past customers have still been able to install our operators but it may require a bit of manipulation to attach the arm to the sash bracket. We also offer the 39-107FK handle and cover kit for these operators. Thanks for posting!
