NICEYRIG 15mm Single Rod Clamp 552 with 3/8''-16 locating hole (for ARRI), cold shoe side mount for EVF/mic setups
Product description
What this clamp is for
This NICEYRIG 15mm Single Rod Clamp (model 552) is aimed at one practical job: giving you a stable, repeatable way to mount a single 15mm rod onto a camera top handle or cage/plate using an ARRI-style 3/8''-16 locating screw. If you’re building up a rig for monitoring, audio, or follow-focus-style accessories, a locating clamp like this can save you a lot of fiddling because it’s designed to align using built-in pins rather than “eyeballing” positioning.
On paper, it’s the sort of component you buy once and then keep using as your kit grows: add an EVF mount, attach a microphone solution, or use the side cold shoe for smaller accessories that suit that format. The downside is also worth noting: it’s built around a specific mounting approach (3/8''-16 locating screw and 15mm rod systems), so if your existing cage/handle doesn’t match that layout, you may end up fighting compatibility rather than enjoying the simplicity.
Key points

The clamp uses a 3/8''-16 locating screw for ARRI-style mounting, then locks down with a thumb knob. Two built-in locating pins help keep alignment steady, which matters when you’re attaching parts you’ll want to reposition later without the whole setup drifting.
It also includes a cold shoe connection on the side of the 15mm rod clamp. That’s useful if you want to mount typical cold shoe accessories alongside your 15mm rod setup—handy when you’re trying to keep the rig tidy near where you’ll actually reach.

Bear in mind: the information provided focuses on how it attaches and what it supports, but it doesn’t spell out load ratings or compatibility with every accessory brand. So it’s sensible to double-check the interface you’re planning to use.
What stands out in everyday use
Where this clamp feels most “worth it” is in the routine of building and adjusting a cage-based rig. The locating pins plus the ARRI-style locating screw approach means you’re more likely to get back to the same physical position after you remove and reattach it. That’s particularly helpful when you swap setups between shoots.
A simple micro-example: you could install the clamp on your camera cage/top handle, slide the 15mm rod into your preferred position for monitoring, then use the side cold shoe to add a smaller EVF-related accessory or a microphone mount that accepts a cold shoe. You lock it down with the thumb knob, test your reach and sightline, then tighten the setup and move on.

Where it may fall short
This isn’t a universal “anything fits” mount. It’s built around a 3/8''-16 locating hole for ARRI-style top handles/cages and assumes you’re already using (or planning to use) a 15mm rod support system. If your cage doesn’t have the locating hole in the way this clamp expects, installation may not be straightforward.
Also, the side cold shoe connection is convenient, but it doesn’t automatically mean it will suit every accessory you might want to add. Cold shoe fittings can be limiting depending on how bulky the gear is and what mounting points your accessory needs.
Who it suits (and who should skip it)



It makes sense if you’re already working in a 15mm rod support ecosystem and you want a clean, stable way to add one clamp point on a cage/top handle for accessories like focus-related add-ons, microphones, or monitoring components.
It might not suit you if your rig uses a different rod standard, doesn’t have the 3/8''-16 locating hole for ARRI, or you need a more flexible mounting style for frequent off-the-cage changes.
Should you buy it?
Worth considering if you prioritise repeatable alignment (thanks to the locating pins), fast adjustments (thumb knob lock), and a two-for-one approach with the side cold shoe for small accessories alongside a 15mm rod setup. It’s the sort of component that earns its keep in real production workflows where rigs get reconfigured.

Skip it if your existing cage/top handle doesn’t match the 3/8''-16 locating screw and you don’t already plan to use 15mm rods—because that’s the foundation this clamp is built on. And if you’re expecting detailed compatibility beyond the mounting interface described, you may want to double-check your specific accessories before committing.
