The CN2207 Downrigger Adapter Plate connects to the Burnewiin UM6080, allowing you to use Cannon Downriggers in your Burnewiin Universal Mounts. This plate is only necessary if you plan to use any of Cannon’s swivel mounting bases. If you do not need their swivel base, the Cannon Universal Mounting Bases (#1904040 – composite, #1904045 – stainless) will bolt directly to the UM6080. Cannon Swivel bases #1903002 and #2207003 use a larger bolt pattern and will require use of our CN2207 adapter plate.WARNING: Cancer and Reproductive Harm -www.P65Warnings.ca.gov
