The rosie handunit bracket is a complete family of remote focus products built around the features ACs kept asking for.
Three things that set the rosie handunit brackets apart:
🔩 Anti-twist pins, removable discs give you three mounting options and keep everything from rotating on you mid-shot.
⚙️ Arri rosettes, yer monitor bracket won’t slip. This is the one that makes the difference when things get bumpy.
🔲 Arri cube holes, standard cube pattern throughout, so you’ve got mounting options for whatever else you want to attach.
Available for every major hand unit system:
Arri SXU-1, Arri Hi-5, Preston HU3/4, Teradek CTRL.1 & .3, Teradek CTRL.5, Tilta Nucleus, C-Motion C-Pro
Ten reviews. Zero below five stars. “Modular design, lightweight, solid build” is how one reviewer put it. Another: “perfect for lightweight setups or mounted directly to yer station.”

Frequently Asked Questions about the Rosie Handunit Bracket:
Does the Preston version work with both HU3 and HU4?
Yes, the Preston HU3/4 Rosie works with both the HU3 and HU4. There’s also a separate Preston HU3/4 Adapter version for adapter-based mounting configurations. If you’re not sure which you need, email us with yer setup and we’ll point you to the right one.
What are the anti-twist pins for?
They’re removable discs that give you three different mounting configurations and prevent the bracket from rotating once it’s positioned. If you’ve ever had a hand unit bracket slowly spin on you mid-shot, you know why this matters. The discs are the fix.
What do the Arri cube holes let me do?
They follow the standard Arri cube hole pattern, which means you can attach any Arri cube-compatible accessory, additional brackets, arms, flags, whatever yer setup calls for. It turns the Rosie into a mounting platform, not just a hand unit holder.
Is there a replacement if the adapter breaks or wears out?
Yes, Replacement Rosie Adapters are sold separately at $25. Available in Arri, flat, and SmallHD configurations.
Can I use it at video village as well as on the cart?
Yes, one reviewer specifically calls this out: “perfect for lightweight setups or mounted directly to yer station.” The Rosie is compact and light enough that it works anywhere you need to park a hand unit cleanly
