Simply unscrew the existing bolt on your double socket arm and replace with this part - replace the adjustment knob and good to go ...

If you are looking to mount more than one device but cannot locate multiple mounting points on your motorcycle or vehicle, this base is the ideal accessory for connecting both devices to one 1" mounting base.

Connect another device to your existing RAM® Mount with the RAM-B-273U Ball Base Adaptor. This ball is made up of a 1" ball connecting to a 1/4"-20 threaded stud with a length of 40.6mm. The threads on this ball replace the bolt in any B-size socket arm, and the ball connects to the middle of the socket arm on the opposite side of the tightening knob.

Dog loved it
Size: One-Size-for-Most
Great! My dog loves taking it outside at night so he can see where it goes easier. Super bouncy, he has had it for over a year now and still not destroyed. Perfect size for his mouth too and easy to clean.

Light up and glow in the dark ball
Size: One-Size-for-Most
Definitely my girls favorite ball 😀. It disappears and I have to buy another one or she goes nuts. Glows in the dark, brighter with more sun. The bounce light up don’t last a real long time, too quick to quit for her but still loves it.

Durable & Bright - Great for Heavy Chewers
Size: One-Size-for-Most
Pros: Extremely Durable: Survived an aggressive chewer where tennis balls failed. Dual-Visibility: Features both internal flashing lights and a glow-in-the-dark "chargeable" surface. Perfect Size: Fits comfortably in the mouth of a 40lb medium-sized dog. Same size as a tennis ball. Cons: Battery Life: Unsure how long the internal flashing lights will last (though it has held up well so far).

Great for night time play!
Size: One-Size-for-Most
This ball is great! It is a 2-for-one light up feature so we love the flashing lights and if she drops it in the snow after those lights stop, we can still find it because of the strong glow that gets its charge from the flashing LED lights. Our first one lasted a few years, we lost it on a trip so now back for our second one so we can keep the night time fetch going! She is a golden retriever for size reference. Any bigger of a breed and I would worry it might be too small for her mouth. It’s a bit smaller than a tennis ball. Just don’t make the same mistake I did and let them have it in the house at night, she walked up to my bedside while I was asleep one night and squeezed it to activate it. Those lights are so bright it was a rude awakening!

Good option for playing at night
Size: One-Size-for-Most
This ball is a good option if your dog likes to fetch at night. It stays lit for about 20 minutes or so, but that is me only leaving it out of the counter, being "charged" by whatever house lights are on. My dog isn't a big chewer, but it seems as though it would hold up well. I like that it is easy to rinse and clean. It seems to be a good value.
