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.

Key Features:
  • Complete flat surface, drill-down mounting solution with an overall height of 7.35"; RAM® ball and socket technology allows for near-infinite adjustability
  • Includes RAM® cable manager to route electrical wiring and cover installation holes
  • Made of Powder-coated, marine-grade aluminum for durability and reliability in the most demanding marine environments
  • Backed by a lifetime warranty
