Size Guide
The RAM Finger-Grip Universal Mount with Medium Torque Base (RAM-B-408-75-1-UN4U) is a versatile, rail-mounted kit designed to securely hold a wide range of handheld devices. The Finger-Grip device holder features three sets of four flexible, rubber-coated finger arms in different lengths, allowing you to customize the grip to your devices exact size. These fingers mount to a backing plate with multiple slotted holes, enabling precise positioning for a firm, secure hold. Once configured, your device can be easily inserted and removed while remaining stable, even in rough conditions. Optional top and bottom supports are included for added security when needed. Paired with the Torque base, this kit is compatible with rails 3/4 to 1 in diameter. Sizing inserts are included to provide a tight fit while also protecting the mounting surface. The RAM Torque mounting base also includes nylon-insert lock nuts to prevent loosening in high vibration environments. The RAM double socket arm and ball-and-socket system provide nearly infinite adjustability, allowing you to achieve the perfect viewing angle every time. It is important to verify the dimensions of your handheld device with its case, sleeve, or skin when determining the overall size.

Features
  • Universal holder with flexible rubber-coated fingers to provide a secure grip of your device; fingers open by squeezing the ends
  • Includes medium Torque™ base that accommodates rails 3/10.16cm (4") to 2.54cm (1") in diameter and a medium length B size RAM® double socket arm
  • Double ball and socket technology allows for near-infinite adjustability of your RAM® mounting system
  • Made of powder-coated, marine-grade aluminum, stainless steel components, and high-strength composite for durability and reliability in the most demanding environments
  • Backed by a lifetime warranty
