The Velux 39-405 : Velux Roof Vent Operator is too small for my application. I was trying to see in the catalog for a Velux skylight operator/ 27"wide and I don't seem to find it. Can you please let me know if you carry such item. If you don't can you tell me where can I purchase the case operator?

I'm having trouble finding a similar operator in that size. If possible, can you show me a couple pictures of your old part? That would be a huge help.
