[Female / Female] Surprisingly very sturdy for its size, bought for macro and travel. Weighs little of nothing.

[Female / Female] I own 2 of this item, one for my shoulder rig and one for my Sachtler tripod, it is so easy to quickly change from one rig to the other on location when shooting. The Redrock baseplate with the Real Right Stuff are a nice couple to quickly and reliably tight the camera to your rig. I own also some other Redrock baseplates with cage but this is the one I prefer for outdoor shooting.

[Aluminum] Bought this case to hold and carry my Gitzo travel tripod with BH-30 attached. Easy to carry. Thank you B&H.

[15 mm] Small and light enough to put in the bag and I load my camera with BH55, that's very stable and smooth operational.

[Aluminum] Very small but capable and strong. Works perfect with the RRS BH-25 ballhead.

[Female / Female] I bought this because I very much enjoy the arca-swiss type quick release system. Prior to using this I had used a normal clamp and mounted a quick release clamp on top of that. The problem with that was that sometimes the quick release clamp would shift slightly, which was problematic most notably in regards to my follow focus. With this everything stays straight and secure which is great. I bought a knob style really right stuff clamp with dual mount instead of the one the lever style they mentioned, because I had been using non RRS plates, and it works great!

[15 mm] I use this with the RRS 28” and 18” camera bars. This clamp is great for mounting collared lenses perpendicular to the track of the camera bar. Contrary to what the other reviewer says, my experience with RRS lever releases has been great and I’ve never “accidentally “ unlocked a lever. The way the end of the lever tucks in around the clamp, you’d have to work at it to catch the lever and release it. Anything will wear out over time but don’t let that scare you. RRS gear is built to last and is backed by a solid warranty and great service. I’ve also had no problem using other manufacturers’ plates with my RRS clamps. �That said, better quality plates that are close to the Arca standard are the way to go. �I’ve used Wimberley, Kirk and Giottos plates with no issues. RRS gear isn’t cheap but in my experience you get what you pay for.

[15 mm] I connect two rods -one vertical to one horizonta-l on the cage to stabilize the horizontal rod.

[Aluminum] As recommended, I acquired the RRS B2-LR-II. If you are doing photo with video inclination this setup is the only one available at this time to have arca swiss accessories mounted to 15mm rods. -pros- High quality, perfect fit. (RRS makes the best and most precise accesories, other brands do not lock in the same especially for lever releases that could just slide off due to microscopic differences in fit vs knob releases that tighten) Connects to the quick release via two supplied phillips screws. Fits both ways to adjust forward or side to side arca swiss plates (connecting via base of camera that goes side to side or via lens foot that goes forward and back) -cons- Price, does not include the RRS B2-LR-II Does not come with the standard RRS Allen key screws, instead you must Carry another tool, the phillips screw driver if you wish to rotate the B2-LR-II Overall, it's made by Redrock Micro to fit RRS. You pay for the quality. With it's various threads this item can fit a tripod attached to the base with another quick release clamp of your choosing with its two different thread sizes which in turn allows some creativity to build up your rig. Five stars because it is what it is and does what it's meant for.

[Female / Female] The exact tool I need to complete my RRS pano set up.
