RAM® Drill-Down Marine Electronic Mount with Cable Manager
Part#:RAM-111-403U UPC:793442008306
This marine electronic mounting kit consists of a medium double socket arm, 2.5" diameter round base, 6.25" x 2" rectangle base, and the RAM® cable manager. The round base includes a 1.5" C size rubber ball and contains pre-drilled holes, including the universal AMPS hole pattern. The rectangle base also includes a 1.5" C size rubber ball and contains a variety of pre-drilled holes that are compatible with several marine electronic devices, including fishfinders and chartplotters. To route electrical wiring and cover installation holes cleanly, this kit also features the RAM® cable manager. While creating a barrier between the surface mount and the attachment area, the cable manager helps to minimize vibration while reducing fiberglass and gel-coat damage.
