Every rig fails at the same place. Not at the camera, not at the light, but at the joint where two pieces of equipment agree to hold each other. The Anchor Point is SmallRig's answer to that joint: a machined aluminum clamp that closes on anything from a 15mm rod to a 44mm pipe, tightens with a single lever, and gives you a 1/4 inch and a 3/8 inch thread so the rig can grow without a second bracket. Two clamps ship in the pack because nobody ever needs only one.
The construction is deliberately unglamorous. Aluminum alloy body, a locking lever instead of a screw knob so it can be tightened with a gloved hand and released in one motion, and a jaw that grips plate glass, shelving, crossbars, umbrellas, and light stands without marking them. The threads are the industry standard pair, 1/4 inch for cameras and small accessories, 3/8 inch for lights, magic arms, and heavier hardware, which means this clamp interoperates with equipment you already own rather than asking you to buy into a system.
What makes a clamp worth paying for is the absence of movement. A cheap clamp creeps under load, and a creeping clamp is a dropped lens. SmallRig machines these to hold a rated load without play, which is why the same part number shows up on film sets, in photo studios, and on the backs of production vans where gear is expected to survive being treated like gear.
Stability is not a feature you notice. It is the thing you notice the moment it is gone.
Why It Earns Its Place
- ✦ 15mm to 44mm clamping range, wide enough to grip rods, seatposts, rails, shelf edges, and light-stand columns with the same jaw.
- ✦ Locking lever, not a screw, so the clamp can be set and released in one motion even with gloves on.
- ✦ 1/4 inch and 3/8 inch threaded holes on the body, the two standards that cover cameras, monitors, lights, magic arms, and microphone hardware.
- ✦ Machined aluminum alloy construction rated for studio and field use, with a body that does not flex under leverage.
- ✦ Two clamps per pack, because a rig built around one clamp always needs a second the following week.
- ✦ Non-marring grip on plate glass, painted shelving, and finished wood, useful when the mounting surface is furniture rather than a stand.
- ✦ Stacks and nests: one clamp can be mounted to another to build an offset arm without additional hardware.
- ✦ Available in 2, 4, 6, and 8 piece packs for studios that build the same rig repeatedly instead of one at a time.

Where It Belongs
The clamp is the least interesting object in any kit and the one that decides whether the kit works. A solo videographer uses two of them to hang a monitor and a wireless receiver off a single tripod leg instead of carrying a second stand. A product photographer clamps a fill light to a shelf bracket in a room with no floor space left. A studio builds eight identical camera positions and buys the eight-pack so every rig is dimensionally the same on every shoot. Outside the camera world the same clamp holds a tablet to a mic stand, a phone to a bed frame, and a plant light to a windowsill. That range is the point: the part is cheap, the failure is not.
Questions Buyers Actually Ask
Q: Will it grip a rod thinner than 15mm?
A: No. The stated range is 15mm to 44mm. Below 15mm the jaw cannot close far enough to hold with rated force, so use a smaller clamp rather than shimming this one.
Q: What is the difference between the 2058, 1138B, and 1124 models?
A: They share the same clamping mechanism and thread pattern and differ in the small articulating or mounting accessory included with the individual clamp. The 2, 4, 6 and 8 piece packs are built on the 2058 super clamp body with the 1/4 and 3/8 threads.
Q: Will the threads hold a heavy strobe?
A: The 3/8 inch thread is the standard for studio strobes and heavier arms, and the aluminum body is rated for that class of load. Check the rating of the arm or stud you attach, because the failure point in a heavy rig is usually the stud, not the clamp.
Q: Does it mark surfaces?
A: The jaw is designed to hold plate glass, shelving, and finished wood without marring the surface. On soft or highly polished materials, place a thin cloth between jaw and surface if the clamp will be under load for a long period.
Q: Can I mount one clamp onto another?
A: Yes. Clamping one super clamp to another is a standard way to build an offset or articulating arm without buying a dedicated magic arm.
Q: Is 260 grams accurate for the pack?
A: Yes, 260 g is the net weight of the two-clamp pack, with a package size of 120 x 100 x 40 mm.
