SMALLRIG Crab-Shaped Clamp with 1/4"-20-3755B

Type: Multi-mount super clamp Model: 3755B Material: Aircraft-grade aluminium alloy + stainless steel Mounting Range: 14mm to 65mm (rods, tables, cages, tripods) Threading: 3 × 1/4"-20 + 1 × 3/8"-16 + ARRI anti-twist locating hole Payload: Up to 3.5kg (7.7lbs) Use Case: Camera rigs, LED lights, monitors, stabilizers, AV setups, site clamps 💥 Why It Deserves Big Compliments This clamp is a proper rig-builder’s dream. The skeletal shark-jaw design grips tight without bulk, and the anti-slip silicone pads keep your gear locked in place—even on smooth pipes or angled surfaces. Whether you’re mounting a monitor to a tripod or clamping a light to a scaffold, this thing holds firm. The multiple threaded holes give you full flexibility—1/4"-20 for standard gear, 3/8"-16 for heavier kit, and an ARRI-style anti-twist hole for pro-level stability. It’s CNC-machined for precision, and the thumb lever makes tightening quick and tool-free. ✅ Big Wins Aircraft-grade build—lightweight, strong, and corrosion-resistant Wide clamping range—fits rods, tables, cages, and more Multiple threads—1/4", 3/8", and ARRI anti-twist for full compatibility Anti-slip pads—secure grip without damaging surfaces Compact and portable—rig-ready for travel or site setups Amazon rating: 4.7 stars from 100+ reviews1 ⚠️ Minor Trade-Offs Single clamp only—no arm or extension included Manual tightening—no quick-release or ratchet No rubber grip on lever—metal-only feel Not for ultra-heavy gear—3.5kg max payload Threaded holes only—no cold shoe or NATO rail 🧍‍♂️ Personal Verdict Used this on a DSLR cage and AV light rig—tight grip, clean threads, and zero wobble. For around £15, it’s a proper clamp that adds pro-level flexibility to any setup. If you want secure mounting without the faff, this one’s a winner.

Well made

I've bought two of these now, they're excellent for clamping around poles or onto flat surfaces like shelves or tables. Unlike the newer versions, this one has the attractive machined aluminium screw handle instead of the ugly steel crossbar

bought several. They work well. 1/4-20 hole for addons. Tightening knob is large and easy to use.

This is a permanent addition to my camera kit bag. I bought it because I could see a use for it, but didn't realise how often I use it, which is why it has become a permanent feature in my kit. I use a Sony A7R3, and with my heaviest lens, it takes it over the rated payload, but still performs well. You may need to be more cautious with heavy equipment like that, my hand is never far away. But in the same breath, not had an issue.

These are good however I would suggest some slightly more grippy surface in the inside of the mouth so that is is less likely to slip. The current covering seems only marginally better than just the metal. So I have had it rotate on the point where it grips as the covering slipped on the wood.

A good superclamp that is well machined and up to its weight limits. Has never failed unlike competitors products. I will say that unfortunately the anodized finish does scratch off rather easily so you will likely see damage around the thread holes very quickly. I do wish the shape of the jaws was better optimised for flat surfaces, but I knew this going in so will not hold it against the product. 5 stars for a decent all round product.

Highly recommended. I got this specifically due to the locking points on the side and it's a great way to mount a mini arm to a tripod for holding a reference monitor such as a Ninja V

Pince en aluminium massif, respire la qualité. Attention les deux bandes noires que l'on voit à l'intérieur des machoires ne sont que faiblement antidérapante. Elle n'est pas seulement excellente pour fixer des gopro ou des éclairages. Elle est aussi très bonne pour bricoler de petites pièces.

sehr massiv und hält die Versprechungen

ottima, fa il suo, attacca bene

Solide klem.

En mi caso, puedo enganchar la cámara a varios lugares a través de un brazo mecánico. Me resulta muy útil
