The Hollyland Screw Fitting for Mars 300 Pro is an official OEM expansion accessory designed to provide an ultra-secure, anti-twist mounting profile for the Mars 300 Pro transmitter and receiver units.

Standard single-screw cold shoe adapters often slip or pivot when your camera rig shifts quickly. This specialized mounting expansion plate screws directly into the chassis of the Mars 300 Pro to convert its base into a completely rigid mount that stays locked in orientation.

 

Core Design & Rigging Features

  • Dual-Screw Chassis Anchor: The plate features two integrated micro-screws that line up perfectly with the native alignment threads on the side or bottom of the Mars 300 Pro housing. By securing the transmitter at two points simultaneously, it completely stops the unit from twisting loose under camera movement.

  • Central Multi-Thread Integration: Once bolted onto the Mars 300 Pro chassis, the raised center portion provides a clean, reinforced $1/4"-20$ female threaded hole. This allows you to attach any standard articulating friction arm, monitor mount, or light stand stud natively.

  • Compact, Low-Profile Footprint: The plate is engineered with form-fitting chamfered edges that match the aesthetics of the Mars series. Its slim profile ensures that it doesn't add bulk or block access to the NP-F battery plate, HDMI ports, or the side OLED status display screen.

  • All-Metal Durability: Machined out of a single piece of high-strength alloy, this plate protects the composite casing of your wireless node from thread stripping caused by overtightening heavy-duty rigging accessories.

On-Set Installation Checklist: When mounting this plate to your Mars 300 Pro, tighten the two outer chassis screws evenly using a small flathead screwdriver or coin before screwing in your primary 1/4"-20 friction arm. Overtightening one side first can cause the plate to sit unevenly, which puts unnecessary stress on the wireless unit's internal threads.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Great quality and folding it in half is a plus. Fits under a seat in car/truck.
Purchased another, as we need one in each car. This is a great ball thrower, especially as it folds in a half. Makes it easy to store under a car/truck seat. Haven’t had any problem with it, great quality!

Fantastic throwing aid!
Very well made, great quality and doesn't feel cheap at all. It's thick, not flimsy or fragile so you can really swing it to launch a ball. Saves my body that I don't have to bend over to pick up the ball anymore, and saves my shoulder that I don't have to hurl the ball anymore. Another bonus is you don't have to touch a slobbered, soggy ball, or a ball covered in dirt. The foldable design is fantastic because I walk everywhere with my dog and don't want to carry around a long stick that's awkward to hold. This folds down small enough that I can securely put it in the back pocket of my jeans without worrying about it falling out. The thing I love most about it is there's a elastic loop at the end so when you fold it you can latch it securely. This small detail is outstanding because I can also hang it on the strap of my sling bag and with the loop secured it will not slip off the strap. This product is so well made and thought out overall.
