An existing RAM-mount system is extremely flexible to use. So if you already have such a system in operation anyway, why not expand it with the matching cup holder?! 1" ball (size B)

RAM mounts are highly flexible. But what exactly do you need?

A working RAM Mount System always exists from a base, a connection/arm and a Equipment holder. This will be a good foundation for your individual holder.

Which basis should you use?

Depending on the weight of the equipment to be installed there are four different systems. These differ mainly by the size of the connection balls from 1 inch to 2.25 inches:

1 inch (size B): For light equipment up to 0,9 kg
1.5 inch (size C): For equipment up to 1,8 kg
2.25 inch (size D): For heavy equipment up to 2,7 kg

For secure attachment of accessories in unsprung industrial trucks, in which very high centrifugal forces can occur, it is recommended to choose a system one size larger than derived from the pure weight.
