Velux Skylight Operator Adapter 39-550

A quick learner from Santa Barbara, CA says:
Dear Swisco,
The Skylight crank adapter 39-550 does not work for my skylight. the male part extending from the hexagon is too wide for the opening and will not fit.
Is there some other solution?
Could i return it be ground down,
Or possible to order just the hexagon lower part without the male extension ?
I have photos i can send on a separate email, let me know if those might help.

Unfortunately, Velux only makes one type of skylight operator these days. It's possible you have an older version, which would be incompatible with the newer hardware we carry. You could try to adapt the 39-550 to work, but ultimately you may need a new operator entirely. If you have pictures, that could help us confirm. You can upload them directly to this thread.
