RAM Mounts Rugged Strap Clamp Rail Mount Holder for Garmin Nuvi 220 500 510 550 ZUMO 220

This mount consists of a v-saddle strap base, double socket arm and custom high strength composite cradle. The v-saddle strap base accommodates rails from 1" to a maximum of 3" in diameter. To mount the base, place the saddle shaped plate on the rail then wrap the metal clamp strap around the rail and plate. Tighten the screw knob on the metal strap with a screw driver until the strap has a firm hold on the rail. The RAM-B-108BU is an alternative mounting base for aircraft such as the Bonanza or Beech with a “throw over yoke”.
