RAM Mounts Double Socket Arm RAM-201U Medium Arm Compatible with RAM C Size 1.5 Ball Components

•Most of the time they use a different kind of rubber for the balls that have a metal base than they do for the composite ones

Mostly metal and attaches to a 1 1/2 inch ball at both ends. A little heavy but I like it that way. This will not break. The handle on the side tightens very well and will keep your fish finder in any position you put it in. I like the long arm better. I can swing it right behind my steering wheel on my boat. You can purchase the base with a 1 1/2 inch ball also. Base did not come with any hardware. I bought a second one after installing the first. This is heavy duty.

Used it with my RAM mount system

Como todo lo fabricado por RAM, muy bien resuelto y de primera calidad. Junto con dos soportes de bola de 1,5 lo uso para sujetar una carcasa estanca para un iPad 2. El cojunto es pesado, pero las bolas aguantan en su sitio sin aflojarse y soporta perfectamente los golpes y vibraciones propias de la navegación

thanks

Works as it should OVER PRICED

Good- expensive but had no other option.

Very happy with my purchase

I have to remove the fish finder each time we use the boat. I like that this arm keeps pressure on one end while the FF is being removed. Works well and holds the FF solidly.

It is attached to Large Ram clamp and is attached to my portable pole mount for my Livescope---no drilling into boat
