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.

Like the other one (Vol 1) but different (Vol 2) with more.
Format: Paperback
Volume 2 continues the great color combinations of the 1st Volume, but the combinations are more complex, with more colors. There's even a section of art in the form of paintings, prints, woven work, etc. that you see on one page while on the opposite page is the breakdown of the colorations in bars with no image. What this does is show how the art works, and then how the combinations also work. Also more of the simplified 2 and 3 combinations that I think I prefer as more minimal. Again, these are ranged from light and airy to darkly saturated -and all curiously satisfying and worth study and trying them out. On the computer it's possible to match any tone or hue, so there's a path that only requires finding the right starting color then paying attention to the combination. Not that it's an end-all, but a beginning. Any of those can be shifted or modified with ease but it depends on how they fit a real-time application and not a formula. But the horizons have already been expanded so there's more, and even more.

Great book to help establish a palette for a software, web or art project
Format: Paperback
I love this book for helping me establish a color palette for art projects that I want a Japanese feel to. Also just generally good for getting inspiration for color palettes that just plain look good. I've always, since I can remember from my youth, felt drawn to the Japanese color combinations in kimono. fashion, origami paper and even toys. Maybe it's a consequence of growing up in Hawaii with all the Japanese influences I had -- or, as I suspect, it's just really good color application. This book helps me find the colors I want that go together the way I want. I use the examples in this book with a Color Muse to pick my digital color palette.

Terrific content, soft cover.
Format: Paperback
It is way smaller than expected but it is amazing in content. The only think I do not like is that it has an extremely soft external cover, which worries me on the long run.
