Please help me identify this operator as I could not find it in the catalog. The exterior screw holes are approximately 4 1/4" on center. The swing arm is approximately the arm that attaches to the sash has a plastic glide and not sure what dimension you need but the ruler is on it. The inside curves approximately 9 1/2 inches The outside curve where the arm meets the gears is approximately 10 1/2 inches. Please keep in mind the cover is permanently attached. Thank you.

Hello,

This is a Truth Maxim operator, which was discontinued and replaced with the 39-438B Encore series, which uses the 39-451 cover and handle. Thanks for posting!
