I have a vinyl awning (top hinge) window that does not lock closed hard. The operator also appears to have been damaged in some way, as when you crank it all the way in the arms block full closure by having the ends interfere with the frame. Only label is the word TRUTH on the operator arm.
I found your operator 39-083 and I will buy that to replace the one I have -- as far as I can tell it is the same size, style, etc etc . The locking mechanism on the arm to window contact is the same type as on this (and the related video.
The question is the two side locks -- and shown in photo #2085. There is NOTHING currently on the window for them to lock onto. Maybe a part fell off -- as you can see on photo #2084 -- there is a hole with nothing in it about where a mechanism should be to catch the locking arm.
I can't find anything that looks likely.... Any guesses?
Thank you for the help !
