QUESTIONS & ANSWERS

Have a Question?

Ask a Question

What is C size?

Unfortunately, we do not have a C Size version of this component. If you'd like to rotate a device using a C Size base plate, you could use RAM-HOL-ROTO1U and RAM-202U.
What is "B" size?

The term 'B size' refers to the ball size, which corresponds to our 1-inch ball.
Is this what I need to adapt Tab-Tite holder for my iPad Mini (A17)? I already have a clamp RAM system for my phone.

Yes this adapter will work with your Tab-Tite™ system, as long as it contains B-size components (1" ball), as this component contains a 1" B-size ball.
