I am selling two Scotty #453 Gimbal Mount Adapters coupled with a Scotty #428 Gearheads. The gimbal mount adapter has prongs that fit into a flush mount rod holder with a gimbal to give a snug fit. The pivot point allows for easy adjustment. The gear track piece accepts Scotty rod holders (not included).
I used a set of these on a previous kayak that came with flush mount rod holders. It allowed me to have a snug fitting and adjustable setup for trolling for stripers. The photo of the green kayak shows a rod in the regular flush mount holder on the left and in a rod holder attached to the gimbal mount adapter on the right.
The asking price is $20 each or $35 for the pair. You can pick them up at my home in Annapolis or can pay extra to have me ship them.
