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.

Box
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
The I absolutely love the shampoo. I have to say that the packaging is super inconvenient. It’s very easy for me to overuse it in the shower and the consistency of the shampoo makes it stick together so it’s not like I can use a drop size come out in clumps.

A very mild shampoo
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
It’s like a watery jelly. It got my scalp and hair clean. It is such a mild shampoo that infuses moisture as well. The smell is light and divine of rosehips. I bought this to replace another brand (SM), and I have no regrets! I can’t wait to try some of their other products. Edited: A year later and Babo has blocked Canadians from ordering their products from Amazon! Such a shame as their products are wonderful. Just use a third party from the USA that will ship out to Canada.

Not for me
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
I appreciate what they are trying to do with the carton however, it’s more splash proof than water proof. The smell is off for me as well. I really wanted to love this product because I love the company but this one is a miss for me.

Great moisturizing shampoo for damaged hair
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
It is a good non toxic shampoo and conditioner, but be cautious it's very moisturizing and not good for oily hair. It works best for dry and damaged hair. A little goes a long way, so don't over shampoo. To my surprise..the container won't get soggy in the shower!
