The FLI PDF focuser uses three long cone point setscrews to connect to this adapter's V-groove. The PDF has a 4.1-inch diameter, 1/4" deep pocket which this mount fits into. This mount presents the OPTEC-3600 dovetail for attachment of any device with an OPTEC-3600 receiver.

A word of caution however, the stepper motor on the PDF is mounted very close to the pocket and protrudes almost 0.6" above the PDF body.
