The worm gear is stripped on the EntryGard for one of our Marvin "French Windows". I think this is the "extra short link arm" version. Please see the attached picture -- would you agree that your 39-334 is the correct replacement? (I had trouble getting accurate measurement of the longer arm --does this vary, too?) thx

I agree, the 39-344 does look like a good match. As long as all the dimensions match those we show on our site then I think you're good to go.
