Wright 07900 operator

A home owner from Frankenmuth, Michigan says:
Wright 07900. The top arm measures 4 inches.The back of the base has the number 7702. As you can see in the picture, the top arm is connected on top, vs. the hinge being on the bottom. We have 5 left hand and 3 right hand that need replacing.

Although we don't need these replaced and I'm not sure if this is relevant, on the arm that is not attached to the operator, but rather attached to the bottom of the window, it says: DEL MAR TORONTO???We think it was a replacement part.

Thank you,

Thanks for posting, Lisa. This looks a lot like our 39-388 and 39-387, but I'm concerned about the bend I see on the link arm. Is that just part of the damage, or is that an intended aspect of the operator? Let me know!

Hi Tom,

Thank you for your response. The bend you see is damage. We believe the windows are too large for the operator and therefore some of the cranks have become stripped and two of the arms have become bent. We'll order one of the 39-388s and see if it works before ordering all of them.

Thank you for your help!!
