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.

Perfect for dry mouth!
I suffer from extreme dry mouth due to sleep apnea and side effects of medications. I used to gargle with mouthwash made for dry mouth before going to bed but it would wear-off by morning.. I’d awaken with severe cotton mouth! What’s worse is my mouth gets dry during the day when I’m out and can’t gargle. It’s so bad I can barely talk! Thank goodness for these melts!! They are GREAT! They stick easily to your gums or roof of your mouth and stay there! They slowly dissolve over night and I wake up without cotton mouth! I keep some in my purse for daytime. They’re better than lozenges or hard candy because they’re discrete. You don’t want to give a speech and be seen sucking on a candy! I use them so often that I was THRILLED to find them in the 100 quantity bottle at a lower price than I could find anywhere else! Protect your oral health and get these pleasant mint tasting melts for your dry mouth!

No more dry mouth at night!
These stick to your gums and keep your mouth moist all night. This makes it easier for me to sleep. I got them on the recommendation of my dental hygienist and have been getting better checkups since I started using them. It keeps your mouth moist which retards the growth of germs.

Great product
These are excellent. They work very well and help ensure a good night's sleep without a dry mouth. Ans the taste is good, unlike Berry Smoothie which is absolutely disgusting.

they work very well - for most of the night. However, cause throat congestion late in the night.
