What does the RAM Mounts assembly kit RAM-138U offer?
The RAM Mounts assembly kit RAM-138U combines a round AMPS base plate with a 63.5 mm diameter, a medium-length connecting arm and a diamond base plate in trapezoid shape into a versatile mounting system. The medium connecting arm offers a base-to-base length of approx. 118.4 mm and thus significantly more reach than the short variant RAM-138U-B with only approx. 63.5 mm. The overall height of the set is approx. 187 mm, providing a comfortable distance between the mounting base and the device. The marine-grade aluminium makes the set particularly resistant to corrosion and therefore suitable for permanent use in wet or marine environments. The patented ball-joint system with C-balls in 1.5-inch size enables infinitely adjustable angles at both ends of the connecting arm.
How does the medium connecting arm differ from the short connecting arm?
The medium connecting arm of the RAM Mounts assembly kit RAM-138U provides a base-to-base length of approx. 118.4 mm compared to approx. 63.5 mm for the short arm of the variant RAM-138U-B. This almost twice as large distance allows the mounted device to be positioned further away from the mounting surface, which in many applications provides a better viewing angle and easier access to the device. The medium arm is the ideal choice for situations where the short arm offers too little reach but the long arm would take up too much space or protrude too far. In vehicles, the greater distance means the screen can be brought closer to the driver without having to relocate the mounting base. On boats, the medium arm provides the right balance between reach and stability for mounting fish finders and chartplotters at the helm.
Which devices can be mounted with the assembly kit?
The RAM Mounts assembly kit RAM-138U is compatible with a wide variety of device cradles from the extensive RAM Mounts range. The diamond base plate in trapezoid shape can accept cradles for tablets, navigation devices, smartphones, fish finders and other electronic equipment. The round AMPS base plate serves as the fixed mounting base and is screwed to the desired surface. The C-ball system with a 1.5-inch diameter offers a load capacity of up to 1.8 kg in standard use and allows infinitely adjustable angles in all directions. The assembly kit is suitable for professional use in vehicles, on boats, in offices, workshops and industrial environments. The shock-absorbing properties of the rubber ball system protect sensitive electronics from vibration damage and extend the service life of mounted devices. Thanks to the modular design of the RAM Mounts system, the individual components of the assembly kit can also be used separately or combined with other elements. The medium connecting arm can, for example, also be used with VESA plates or suction-cup bases, while the base plates can be combined with alternative swivel arms. This flexibility makes the set a future-proof investment that can adapt to changing requirements. Compared to the short variant RAM-138U-B, the medium arm offers noticeably greater reach with only marginally more space requirement. The 30-year warranty from RAM Mounts attests to the manufacturer's confidence in the quality and durability of this professional mounting kit for daily use in vehicles, on boats and in industry. All components are supplied ready for assembly in a polybag.
