The Millennium Marine Spyder-Lok Base Plate is an extra base plate for your R-100 rod holder.
The SpyderLok series of fishing rod holders are very popular with anglers. Many fishermen prefer more than one spot on their boat to set up a fishing rig. Pick up one or more of these flush mounting base plates and enjoy the versatility that comes with the ability to have multiple rod holders or to move one rod holder from base to base. The R101 Base Plate weighs 1-pound and mounts flush to the carpet.
