SMALLRIG Crab-Shaped Clamp with 1/4"-20, 3/8"-16 Locating Hole for ARRI, Payload 7.7lbs/3.5kg, for Most Photographic Accessories - 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.

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

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

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.

Really good clamp, very strong. Occasionally has a problem where the actual handle can come loose but I did have a replacement sent free of charge which seems to be holding up better.

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.

decent clamp, rubber bit is a bit stiff and slippery on a smooth surface but I'm ok with that. I'm going to glue a strip of an old bike inner tube to give it more compliance and grip. happy with the clamp overall.

If you need a sturdy mount that is versatile and well made, this is it.
