The KR VisionReach 22 Super Knuckle 8 cm (3 in) is the mount that brings a camera, light, sensor, or monitor out from a VisionGrid 22 Pro frame to where it needs to look. It clamps to the 22 mm tube, gives you a fast knuckle arm for positioning, and ends in a standard ¼"-20 screw for your device.

The Super Knuckle is a double ball-and-socket arm - a ball joint at each end held by a single central knob. Loosen that one knob and both joints swing free for fast pan-and-tilt positioning; tighten it and the whole arm locks at once. At 8 cm (3 in) it is the shortest in the family - the stiffest, strongest, and quickest to set of the Super Knuckle lengths. For fast, close-in camera and light trials on a VisionGrid 22 Pro bench, this is the natural first choice.

A generic arm can hold a device for a while. VisionReach is built for setups that keep changing - you reposition the camera, swap the light, adjust the angle - without the arm slipping, twisting, or drifting out of position.

It's a known, reusable mounting path: a defined base that fits your frame, a defined arm class with a real load figure, and a standard device screw. When the layout changes, you adjust the arm instead of rebuilding the mount. If your camera needs a special interface, keep this as the standard mounting path and make only the device-side adapter plate custom - the rest stays reusable.

This kit is the middle link of the chain - it connects your 22 mm VisionGrid Pro tube to your device's ¼"-20 thread, base and arm included:

¼"-20 is the common camera/accessory thread. "Male" means this kit provides the screw; your device or adapter plate needs the matching female thread. If the image must stay level and can't twist on a single screw, add a locating pin or anti-rotation plate.

Choose Super Knuckle when you want fast, freehand positioning - one knob frees both ball joints to glide to any angle, then locks them together, and it has the widest range of accessories. Choose Omni when you want more reach, higher load, or a repeatable angle you can return to exactly - that's what its rosette lock is for. They hold differently: Super Knuckle for quick, free movement, Omni for a locked, repeatable angle.

This Super Knuckle reaches 8 cm (3 in) and carries up to 5 kg / 11 lb close to the clamp - the strongest and steadiest Super Knuckle length, derating toward the tip. It is friction-held with a single knob - fast and freehand, but with no indexed angle return, so re-aim by eye after a bump; it is a positioning tool, not a production mount.

• Reach: 8 cm (3 in) nominal.
• Close-in working load: up to 5 kg / 11 lb - the highest of the Super Knuckle lengths.
• Best for: machine-vision cameras, lights, sensors, monitors, and accessory plates that sit close to the frame.

Start with the shortest arm that reaches the target. The shorter Super Knuckle is cheaper, carries more load, and holds steadier - every extra inch of reach costs you money, payload capacity, and stability. The 5 kg figure is a close-in reference for the arm; usable load still depends on payload position, mounting angle, vibration, and cable pull. Secure the cable to the frame before judging stability - cable drag can shift a camera even within the load range. For work that must return to an exact, repeatable angle, the Omni's rosette lock is the better fit.

VisionReach 22 Super Knuckle 8 cm (3 in) is at its best for fast, freehand camera and light positioning on a VisionGrid 22 Pro bench - where quick repositioning by hand matters more than a locked, repeatable angle.

• Fast close-in camera and light positioning on a VisionGrid 22 Pro bench.
• Quick reconfiguration in integrator labs and prototype cells.
• Trials where repositioning speed matters more than maximum rigidity.
• Cable-managed setups within the arm's load range.

The kit ships as three parts - the sliding base, the 8 cm (3 in) Super Knuckle arm, and the ¼"-20 male device screw - and nothing device-specific.

• VisionReach 22 tube clamp base for the 22 mm VisionGrid Pro tube.
• Super Knuckle 8 cm (3 in) arm.
• ¼"-20 male device screw.

Not included unless bundled: the camera, lens, light, sensor, monitor, or controller; a camera-specific adapter plate; the VisionGrid frame itself; and cable strain-relief hardware.

Before ordering, confirm four things: a 22 mm VisionGrid Pro tube, a ¼"-20 female device thread, payload and cable pull suited to an 8 cm (3 in) reach, and a reviewed path if the setup is vibration-prone or production-bound.

• Confirm your frame is a 22 mm VisionGrid Pro tube (not 16 mm rail, 35 mm post, or extrusion).
• Your device needs a ¼"-20 female thread, or an adapter plate that gives it one.
• Check that payload weight, center of gravity, and cable pull suit the 8 cm (3 in) reach.
• If the setup is vibration-prone, overhead, in a moving-machine area, or headed for production, talk to us about a reviewed mounting path first.
