Camera Mount Clamp, Super Crab Clamp with Rotatable Clamping Block, 1/4" and 3/8" Thread Holes for Round Pipe Flat Surface, Camera Mounts, and Other Photographic K&F CONCEPT
SKU: KF31.218
As is well known, I am a big fan of K&F Concept products, simply because you almost always get very good quality at an astonishingly low price.
The multifunctional Super-Clamp tried out here is no exception and is not only surprisingly solid and robust, but the small Super-Clamp does not have to hide in terms of quality. In my opinion, it is definitely more durable than you would expect due to its compactness

The super clamp impresses with its excellent workmanship and high quality. It sticks reliably to table edges or pipes without slipping and provides a safe feeling when in use. The integrated thread makes it easy to attach a wide variety of equipment, which makes it particularly versatile. In combination with a Magic Arm and a lamp, it is ideal for positioning lights or accessories stably and flexibly. Overall, a robust and extremely practical clamp for versatile setups.

The (new) clamp has the advantage over the previous model that you can not only clamp rods but also straight surfaces. Thanks to the two joints, you have significantly more applications here.
There are a total of 3x standard tripod threads for further use, which can then be used to create various applications. To ensure that everything lasts, the system is made of metal and is
therefore super stable.
Also worth mentioning are the rubber pads for the connection to the clamp, so that even slippery areas hold better.

This super clamp from K&F Concept differs slightly from the usual super clamps. There are two movable supports at the tip of the claw, which ensure that the clamp adheres significantly better to straight surfaces, i.e. to a table top, a board or a sheet of metal. Although the clamp is about the same size as my other super clamps, the inner diameter is a few millimeters larger here. Unfortunately, this means that thin pipes cannot be jammed. This shouldn't be a problem for the legs of standard stands. The inner diameter is too large for the thin tubes of a Magic Arm or the frame of my photo box; the clamp cannot be held. I have attached a photo of a standard super clamp from K&F Concept and this model. That's where the difference is easy to see. If you have the application of clamping thin pipes, you have to use another model.
Otherwise, the K&F Concept clamp is very well made. All mechanical parts run very smoothly and the surfaces look high-quality. For me, this is a convincing product, especially when you can do without clamping small pipe diameters.
My rating: 5 stars — perfect product, or at least almost

I was really impressed by this photo clip. The workmanship is absolutely flawless and looks high-quality — nothing wobbles here, nothing rattles here. The sophisticated approach is particularly convincing for use on flat surfaces such as table tops, but also on round bars. Thanks to the adjustable clamp blocks, it grips reliably and securely, whether at a desk or on a pole in a studio setup. The anti-slip pads also ensure a firm fit without damaging surfaces.
In practical use, especially in the areas of photography and lighting, the clamp shows its strengths to the fullest. It can be tightened precisely and powerfully and keeps the assembled equipment absolutely stable in position — exactly what you want when changing setups. The various thread options are particularly positive: Two smaller and one larger thread offer great flexibility when attaching accessories such as Magic Arms, monitors or LED lights. This opens up many creative options and makes the clamp a real all-rounder in the setup.
All components are made of metal, which not only ensures durability, but also creates confidence in stability — even though this is of course reflected in the weight. I would therefore be a bit careful when using very long cantilever arms. In typical areas of application, however, the clamp is convincing. It is also visually successful. For me, it has now become an integral part of my setup and a clear recommendation!

To be honest, when I unpacked the clamp, I was surprised how small it actually is - on the other hand, the dimensions were given correctly and the item corresponds exactly to the description. This type of clamp comes from industrial applications and is used, for example, in metal construction. I would even say that every welder or stainless steel professional uses these extremely strong industrial clamps.
In principle, they do the job of a screw clamp, but they have several enormous advantages:
- Due to the much smaller space requirement, they can be used in confined situations.
- It can be attached very easily with one hand
- The screw path is shorter, a few turns are enough and the thing fits perfectly - The lever travel is much more effective than with a normal clamp
- so the clamp holds even when vibrated.
- The clamp holding force is incredibly strong.
Unfortunately, the contact surfaces on this clamp are quite small - a set of 3 with different sizes in this quality would be brilliant. Speaking of quality: It's amazing - the rotary lever is made of solid aluminum, easy to grip and operate. The jaws are made of steel, nothing wobbles, nothing rattles, everything feels full and solid.
In short: This clamp fulfills the product promise 100% and should not be missing in any workshop (preferably in multiple versions).

Very high-quality all-purpose clamp with 1/4 and 3/8 inch thread connections, which can be used for all kinds of mounting purposes (not only in the video/photo area).
The design is also very well done for the eye, there is nothing to complain about here, even the price is fair.

As a photographer and videographer, I already use numerous products from K&F Concept in everyday professional life, including various magic arms, clamps and holders. The super clamp with adjustable clamp blocks is an ideal addition to my existing system for securely fixing accessories to stands, table edges or pipes. My first impression after unpacking confirms the brand's usual high quality: Despite its low weight of only 125 g, the clamp looks extremely solid and valuable.
Workmanship and feel
The material quality is impeccable and designed for tough everyday work. All edges are cleanly deburred and the mechanism runs smoothly, but can still be detected with a very high torque. The integrated rubber pads inside the jaws are particularly important for my work. These guarantee a non-slip grip on smooth surfaces and at the same time reliably prevent damage to my high-quality equipment or furniture.
Flexibility and practice
The special feature of this clamp lies in the rotatable clamping blocks. These allow an extremely secure grip on flat objects such as table tops up to 50 mm thick. If I need the clamp on round tubes or stand legs, the blocks provide a perfect recess for diameters between 20 and 60 mm. This flexibility is irreplaceable in kit construction, as I can use the clamp on solid plates as well as on thin trusses or even branches outdoors. Without the clamps, it can also be fixed even more directly to pipes.
Compatibility and system integration
Since I design my entire setup modularly, the existing 1/4 inch and 3/8 inch thread holes are essential. I can seamlessly combine the clamp with my existing Magic Arms to precisely position monitors, microphones, or LED lights. The threads are precisely manufactured so that nothing wobbles or comes off unintentionally even under heavy loads. Thanks to its compact design, it takes up hardly any space in the camera bag.
Conclusion
The K&F CONCEPT super clamp impresses with its professional workmanship and the sophisticated construction of the clamping jaws. For me as a user who already fully relies on the K&F Concept accessory ecosystem, this tool is another reliable component for stable and creative camera setups. It offers an excellent ratio of dead weight to payload and is intuitive to operate.

This is a quality piece of hardware that is well-thought out. Everything from the construction to the weight of it in my hand lets me know it's well-made and they understand how people are going to use this. It seems built to last.
I like that the little pads easily flip out of the way to allow for clamping to a pipe.
There are two mounting points for 1/4" (with holes for anti-rotation studs) and one for 3/8"
The color is actually very nice.
