Questions & Answers

Have a Question?

Ask a Question

Does this come with a larger ball?

No, but you can attach one of our RAM-202U C size round plate with ball to our Bond A Base to create a similar base mount.
The mount didn’t have any instructions for mounting this, what is the tube of glue and alcohol prep pad for? Are there preferred mounting surfaces? Are there preferred mounting angles (should the pad be in shear or compression?).

On this product page if you click Resources and see the INSTALL GUIDE. Flex adhesive ball base provides a strong mounting surface in a wide variety of use cases, such as a vehicle dash. If you got the X-Grip with your order the tube of glue is to put in the caps before you put on the medal legs. This is to give you a longer lasting hold.
How do you remove the base from one location and move to another surface? Is the adhesive reusable?

The adhesive is difficult to remove and reuse, please see RAM-202PSAU for additional 3M adhesive.
Do you have an option where a threaded ball can be screwed into a streamlined base such as this? I'd love this for my paddleboard, but it would work so much better if the ball head could be removed from a permanently mounted base...

The Bond A Base adhesive base mount allows you to use either a drill down base or a track ball as the attachment point. The RAP-398-BLK-202U is the version that uses a drill ball base like the RAM-202U, while the RAP-398-BLK-TRACK-AU is intended for use with one of our track balls like the RAP-354U-TRA1 or the RAM-463-TRA1U, both of which are removeable.
Will this work on a textured vertical surface of a dash (versus a horizontal dash) to hold an phone?

Yes, the RAP-B-378U is a good choice for a vertical mount in places where a drill down base isn't an option.
Will this stick and hold well to the plastic dash in a utv

Yes, the RAM-B-378U is a good option for textured or porous surfaces that a suction cup would not be suitable for.
In order to select the correct glue, I need to know what kind of plastic the base is made of.

The RAP-B-378U comes with a double sided adhesive pad from 3M, no additional glue or other adhesives are required.
The adhesive pad has yellow paper on one side and black clear plastic on the other. Which side should adhere to the ball base and which to the surface? Or does it matter?

No, it does not matter which side you use to attach to the Flex Adhesive Ball Base or the mounting surface. The adhesive is the same on both sides of the disk.
Is this removable without damaging the dash?

Yes, the Flex Adhesive bases like the RAP-B-378U can be removed by using a hair dryer or heat gun on a low setting and applying hot, moving air to the base itself. The adhesive will turn more tacky than sticky and you will be able to slowly and carefully peel the base off of the mounting surface.
