Headrest Bar Device Mount with Integrated 20mm Ball fits bars 3/8" to 5/8"

Went in extrememly easy. Perfect mounting solution for my son in his carseat.

Let me start with the bad & end with the good!
#1. When you see the online pics for the "Cowboy Hat Holder," you will notice a couple pics showing the Headrest Bar Device Mount alongside the Cowboy Hat Holder. This automatically gives the impression that it''s "included" with the Cowboy Hat Holder.
#2. In the Versatile Mounting Options for the Cowboy Hat Holder. it states "We recommend pairing the Cowboy Hat Holder with our Headrest Mount and Micro Mounting Arm or our Nubby Edition Headrest Mount. This should read that you will need to "purchase" the Headrest Bar Device and either the Micro Mounting Arm or the Nubby Edition Headrest Mount! It was only when I opened the box containing the Cowboy Hat Holder, that I realized I was going to either have to return it or purchase the "required" hardware to mount it. I "reluctantly" made the decision to order the Headrest Bar Device Mount. I was very fortunate to already have the Micro Mounting Arm, as I previously installed the Dual iPhone Mount with an Arm Extension (review previoulsy submitted) & since I used the Arm Extension, I had an extra Micro Mounting Arm.
Now for the Good:
After I finally had this Headrest Bar Device Mount, I was able to install my "much needed" Cowboy Hat Holder (review previously submitted)!

I built two custom headrest rigs using Bulletpoint parts, and I’m beyond impressed. Each seat uses the Headrest Bar Device Mount with Integrated 20mm Ball (fits 3/8”–5/8” bars), connected to a 1cm Carbon Fiber/Kevlar Hybrid Mount Arm – Matte Finish, and finished with the Aluminum 15mm Connector Ends to attach a pair of kids’ rear-facing baby car cameras (6.9” ultrawide display). Everything fits perfectly.

The result? The cameras are rock solid—no shaking, no sagging, and no more ugly straps hanging off my headrests. It looks clean, professional, and fully adjustable. The plan is to upgrade these same mounts later to hold tablets, and the modular design makes that simple.

Bulletpoint’s accessories are seriously badass—strong, precise, and built for people who want to create organized, purpose-built setups that actually last. Hands down, the best mounting solution for my creativity and organization. Highly recommended!

Fit perfectly very sturdy . Able to mount a 10in tablet and works very well.
