RAM-101U-189BU – RAM® Twist-Lock™ Dual Suction Cup Base with C Size Arm & AMPS Plates

The RAM-101U-189BU is a heavy-duty mounting base that sticks to a windscreen or smooth surface with twin twist-lock suction cups, then carries a RAM or third-party cradle on a C size double socket arm. The two AMPS round plates connect to a wide range of cradles, including all RAM iPad cradles, and the ball-and-socket arm dampens vibration while adjusting to almost any angle.

Key Features

  • Twin twist-lock suction base for windscreens and other smooth, non-porous surfaces
  • C size double socket arm with the larger 1.5" ball for extra load capacity; near-infinite adjustment
  • Two AMPS round plates with both 3-hole and 4-hole patterns connect to most RAM and third-party cradles, including all RAM iPad cradles
  • Powder-coated marine-grade aluminium, powder-coated steel and high-strength composite; backed by a lifetime warranty

Most RAM and third-party device cradles with a 3-hole or 4-hole AMPS pattern. The suction base mounts to flat glass and other smooth, non-porous surfaces. For strongly curved surfaces, consider the articulating RAM-189B-PIV1U base instead.

FAQs

Will it hold on a curved windscreen? The twin cups are best on flat glass or smooth non-porous plastic. For a strongly curved surface, the articulating RAM-189B-PIV1U base is the better choice.

What cradles fit it? Any with a 3-hole or 4-hole AMPS pattern, including all RAM iPad cradles and many third-party holders.

Stylish and affordable!
Color: Grey, Size: 4 Pack, Color: Grey, Size: 4 Pack
These shelves are rey stylish, light and durable! The set came with everything needed to install. The color is just as described. Price is steal and these shelves can definitely be used anywhere throughout the house. I did give it only 4 stars because as you can see in the photos, the underneath was not completely finished. Decided to keep because the price was unbeatable.
