Hey there!

Thank you for reaching out to us. I wonder if you might have the 39-253RB operator, which uses the 39-529 track slider (sold separately). We recommend reviewing the specifications below to confirm.

Note that the 39-376 and 39-452 are also sold separately.

Please let us know if you have any questions.
