The Hollyland Crab Clamp is an official heavy-duty OEM grip utility accessory engineered to mount and secure Mars and Cosmo series wireless video transmitters, receivers, and field monitors onto standard production support hardware.

In dynamic shooting environments—like tracking vehicle mounts, grid pipes, heavy C-stands, or tripod legs—standard cold shoe adapters lack the structural clamping force needed to hold heavy gear securely. The heavy-duty crab clamp serves as an industrial all-metal vice, allowing camera assistants and grips to firmly lock premium video transmitters onto almost any structural surface with confidence.

Core Structural & Grip Features

  • High-Torque T-Bar Locking Lever: Built with an ergonomic metal T-handle screw assembly. This large handle provides excellent physical leverage, letting you crank down the clamp to achieve a rock-solid, vibration-proof grip by hand without requiring extra tools.

  • Dual Threaded Accessory Mounting Ports: The chassis features integrated, reinforced 1/4"-20 and 3/8"-16 female threads. This lets you mount industry-standard friction articulating magic arms, continuous power blocks, or standard Hollyland shoe studs directly onto the clamp housing.

  • Textured Non-Slip Rubber V-Groove Jaws: The interior gripping surfaces are lined with high-density, texturized rubber padding molded into a sharp V-groove channel. This design maximizes surface contact, preventing the clamp from twisting or slipping out of place when locked onto smooth, polished metal speed-rails or C-stand arms.

  • Massive Jaw Clamping Range: Capable of opening wide to slide onto bulky structural square beams or thick pipe columns, while still closing down tightly enough to bite onto thin sheet metal brackets, lighting pins, or stabilizer handle tubes.

System Interoperability

This universal mechanical grip tool interfaces with any professional hardware using standard photography threads, and is explicitly matched with:

  • Hollyland Wireless Ecosystems: Supports the physical weight of the Mars 300 Pro, Mars 400S Pro, Mars 4K, Cosmo C1, and the Mars M1 / M1 Enhanced wireless transceiver monitors.

  • Production Support Rigging: Clamps securely onto industry-standard $5/8$-inch ($16\text{mm}$) baby pins, C-stand extension arms, camera crane tubes, tripod legs, motorized gimbal handles, and studio lighting grid pipes.

On-Set Mechanical Rigging Best Practice: When mounting your wireless video transmitter onto a high-vibration environment—such as a car-to-car tracking rig or a chase vehicle—never mount the crab clamp directly to the thin outer skin or fragile cosmetic trim of the vehicle. Always anchor the clamp onto a structural metal frame point, solid bumper bar, or heavy tubular roof rail. Once the clamp is cranked hand-tight, thread a steel safety cable through the cage of your transmitter and loop it tightly around the main support structure to serve as a secondary fail-safe backup.

Very Good Quality 👍🏾
Color: Gold Polished, Color: Gold Polished
Good quality. Study with some weight to it. Was pleasantly surprised at how good this looks. The gold color is very shiny which is what I was looking for. The base is large enough to hold a thick roll of Viva paper towels.

Great Paper Towel Holder! Sturdy and Stylish
Color: Black
I’ve been using this paper towel holder for about 6 months now, and I’m very happy with it! The design is sleek and modern, making it a perfect fit for my kitchen. It’s made from durable steel, and I love that the finish still looks brand new after months of use. The best part is how easy it is to replace rolls. I can quickly swap out old rolls without any hassle. The weighted base and non-slip pad are fantastic features – I’ve accidentally bumped it a few times, and it hasn’t tipped over once. It stays securely in place, which is a huge plus. I also appreciate that it’s versatile enough to fit all paper towel sizes. Overall, this is a high-quality and functional product that’s also aesthetically pleasing. Highly recommend it if you’re looking for a sturdy, easy-to-use paper towel holder!

Perfect!
Color: Warm Gold, Color: Warm Gold
Been using this thing for over a year now and it is fantastic. The color is beautiful and as described. The price was a very good price point. The size is everything you need it to be because it’s nice and sturdy; it holds a big Costco size roll. And the roll actually fits over the top. You don’t have to unscrew it. In love.

Stylish and sturdy paper towel holder
Color: Gold Polished
This gold paper towel holder looks great on my counter and works perfectly. The base is nice and heavy keeping it sturdy, which keeps it from sliding or tipping when I pull off a paper towel. I’ve had no issues with the roll coming loose or falling off, even when grabbing sheets quickly. It’s both functional and elegant. Gives you good value for the money. Definitely worth it if you want something that looks good and stays in place.
