Hello,

The diagram below shows the dimensions of the opening that accepts the operator arm roller that glides in the 39-505 track. If you don't think these dimensions will work for you, I would recommend showing us a photo of the operator, including the arms that operate the sash, so that we can identify the operator and the related hardware that it works with.
