Our Double Rod-Holder Mounting Plate is designed to be used with both Cannon and Scotty Downriggers, and allows you to mount TWO of our RMFG-ASRH adjustable/swivel rod holders, one on each side of your downrigger. The bat-wing style puts both rod holders in the best possible position for effective fishing. A must for charter operations and those who like to stack their gear when chasing big fish. Ships with installtion hardware/fasteners. Doe NOT include rod holders.
