The KR VisionReach 16 Super Knuckle 23 cm (9 in) is the mount that brings a camera, light, sensor, or monitor out from a VisionGrid 16 frame to where it needs to look. It clamps to the 16 mm rail, 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 23 cm (9 in) it's the longest in the family - the most reach for getting around a sample or covering a wider area. Longer reach means more leverage, so it carries less than the shorter arms and is best with lighter payloads.

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 16 mm VisionGrid rail 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 23 cm (9 in) and carries up to 2 kg / 4.4 lb close to the clamp - the longest reach, so keep payloads light - 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: 23 cm (9 in) nominal.
• Close-in working load: up to 2 kg / 4.4 lb.
• Best for: lighter cameras, lights, sensors, and accessories that need extra reach.

Start with the shortest arm that reaches the target. The shorter Super Knuckle is cheaper, carries more load, and holds steadier - so choose 23 cm (9 in) only when you genuinely need the reach, and plan for a lighter payload. The 2 kg figure is a close-in reference for the arm; at this length, leverage, sag, vibration, and cable pull all reduce what it will hold steady. Secure the cable to the frame before judging stability. For work that must return to an exact, repeatable angle, a shorter arm or the Omni's rosette lock is the better fit.

This Super Knuckle is at its best for fast, freehand camera and light positioning on a VisionGrid 16 bench, where quick repositioning matters more than a locked, repeatable angle.

• Longer-reach camera or light placement on a VisionGrid 16 bench.
• Getting a device around or over a sample where a short arm can't reach.
• Early layout exploration before settling on a shorter, stiffer final arm.
• Cable-managed setups with lighter payloads.

The kit ships as three parts - the sliding base, the 23 cm (9 in) Super Knuckle arm, and the ¼"-20 male device screw - and nothing device-specific.

• VisionReach 16 sliding base for the 16 mm VisionGrid rail.
• Super Knuckle 23 cm (9 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 16 mm VisionGrid rail, a ¼"-20 female device thread, payload and cable pull suited to a 23 cm (9 in) reach, and a reviewed path if the setup is vibration-prone or production-bound.

• Confirm your frame is a 16 mm VisionGrid rail (not 22 mm tube, 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 23 cm (9 in) reach - plan for a lighter payload at this length.
• 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.
