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.

Takes time to install right.

Saw a few complaints about this product in the reviews before ordering but gave it a shot anyways. Took a little longer than I would have liked to install, but was only time consuming, not difficult. I made sure at least 2 screws on each base plate were into studs so it's more than sturdy. Hung each of the 3 brackets by 1 screw, marked the rest of the holes, took it back off the wall, installed anchors where needed, and finally screwed each back up fully. And for the people saying that the threads don't line up once snug, try switching out a fitting or pipe so it's a different thread mesh. If that doesn't work, just over tighten the fitting. Furthest one I pushed was nearly 3/4 of a turn past finger tight. I don't have a single loose connection on the whole shelf. My wife can't wait for us to go to lowes tomorrow for the wooden shelves to finish off the bookshelf this will be for her.

Worth the money!

Such a good buy! High quality and easy to assemble. I will warn that hanging them is a little tricky (We read several reviews saying this and thought “they’re just dumb”, we were definitely wrong. I recommend installing/ attaching the middle level of plates first before attaching the tops and bottoms. It just made it easier for us to keep everything level throughout the process) but other than that very happy with this purchase! We hung three 12 inch boards inside and it added SO much storage and looks so nice! Definitely worth the money!

Takes up a lot of visual space
Size: 3 Set 4-Tier, Planks Not Included
Great product. Goes together easily and quickly. Everything was there that was needed. Looks great and is consistent with my industrial look; however, we're converting a stairwell to the basement to a pantry and wanted to use these shelves there. It takes up an inordinate anount of visual space and made it feel claustrophobic to me. I tried to come up with someplace to use it, but it's a very small house. If you have the space, you won't be disappointed with these shelves.
