FANAUE Aluminum 20mm Ball Head Double Socket Arm Only Supports Installation of 20mm Ball Head Adapter, Connects Phone Clip and 20mm Ball Base and Can be Assembled Into Bike Motorcycle Phone Holder

Holds my mount very firmly. This is simple and super easy to use. It fit the 20mm balls perfectly. I can adjust on the fly easily too. I think this part will last forever.

Great product, super durable as it's made out of aluminum. Would highly recommend.

What I expected. Good solid construction.

I now have a magic arm that serves as an adapter. The machining is nice, and the action of the know is very smooth. the sockets grab the ball ends of the connectors firmly, and when set up, nothing drifts. I now have a magic arm that can take the weight of my mirrorless camera, and it pairs nicely with a crab claw! This will inevitably find its way into the kit of anyone who uses ball and socket mounts!

High quality. It doesn’t loosen up on bumps like the others. I installed it in my Jeep Wrangler.

Great value, good adjustability and durability.

Good quality!

Heavy duty extension arm. Should last a lifetime.
