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.

Last about a year ishhh
Size: Single Slat, Color: Glossy Black&M-Color
Plastic mold isn’t as straight as it should be, the clips don’t line up like oem. Product is wiggly. Had on car for over half a year. Hasn’t faded. Just wish the fitment was better. Update: the grill lasted about 1 1/2 years, it began to fade, and I had a slat crack, no evidence of impact. I ended up buying a better made product and replaced this grill.

Fits a 2001 330!
Size: Single Slat, Color: Black, Size: Single Slat, Color: Black
The grill in my old 2001 330 broke off and I was really happy to find a nice looking replacement at an inexpensive cost. The black looks really sleek on it and has breathed some new life into it. Next up is to replace the emblem.

Direct Fit and good quality
Color: Single Slat Gloss Black, Size: 2002-2005 E46
For anyone that has owned an E46 knows that even the stock kidney grills are brittle plastic. This aftermarket is about the same quality as stock. It is a direct fit and has the clips where they are supposed to be to keep them in place. The look is also pretty nice. This one is all black and actually looks nice on my black E46. I would recommend especially for the price and shipping was fast.
