The KR VisionFrame 35 Super Knuckle 23 cm (9 in) puts a camera, light, sensor, or monitor out on a freestanding 35 mm post frame, with the longest Knuckle reach for lighter payloads that need to sit away from the post.

It mounts to a vertical 35 mm VisionFrame post with a Super Convi clamp - the jaw grips the post and the hex receiver locks the arm's 5/8" (16 mm) stud with a spring-safety catch - then gives you a quick-adjust Super Knuckle arm to aim the device, ending in a standard ¼"-20 screw.

The Super Knuckle is a double ball-and-socket arm with a single central knob: loosen it and both joints swing freely to any angle, tighten it and the whole arm locks at once. The friction ball joints glide smoothly, so you find a position fast by hand. At 23 cm (9 in) it is the longest Knuckle in the family - pick it when reach matters more than stiffness, and keep the payload light.

VisionFrame 35 is a larger prototyping and integration frame - the route for testing bigger camera-to-product geometry, taller camera positions, and multi-camera layouts before the final machine is built. The camera, light, sensor, adapter plate, and cable management are chosen separately, so you build the exact setup your scene needs.

When the inspection scene is too big for a tabletop - taller camera positions, more camera-to-product distance, a larger sample, or a conveyor-style mockup - VisionFrame 35 gives you a freestanding 35 mm post frame to build on. Clamps slide up and down the post, so you can move a camera or light to a new height without cutting a custom frame.

This is a prototyping and integration frame, not a production station. An integrator uses it to stand up larger geometry fast, prove the inspection, and show a customer. Once the layout is locked, the production path becomes a VisionCell inspection cell, a SightLink E3040 retrofit onto a real machine frame, or a custom engineered fixture.

This kit is the middle link of the chain - a Super Convi clamp grips your 35 mm VisionFrame post and the arm carries your device's ¼"-20 thread, clamp 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 - its friction ball joints glide smoothly to any angle and lock with a single central knob, so you set a position by hand in seconds. Choose Omni when you want a repeatable, locked angle - its anti-slip rosettes index to a set tooth position and return to it, so a camera holds the angle you set. They simply hold differently: the Super Knuckle for quick, free movement, the Omni for an exact, 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 to sit out away from the post.

Use the longest Knuckle only when you need the reach. More reach means more leverage, so the 23 cm (9 in) carries less and is less steady than the shorter arms - every extra inch costs payload capacity and stability. The 2 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 post before judging stability - cable drag can shift a camera even within the load range. For a camera that must hold a precise angle, prefer the 8 cm (3 in) or 15 cm (6 in).

Use the Super Knuckle 23 cm (9 in) when a lighter device has to reach well away from the post:

• Lights, sensors, or accessories positioned out over a larger scene.
• Reaching around a sample where shorter Knuckles can't.
• Freehand setup and teardown during demos and trials.
• Secondary camera or light angles where the payload is light.
• Cable-managed setups within the arm's load range.

The kit ships as three parts - the Super Convi clamp, the 23 cm (9 in) Super Knuckle arm, and the ¼"-20 male device screw - and nothing else; the 35 mm post and the device are separate.

• Super Convi clamp (ratcheted handle) for a vertical 35 mm post - jaw fits 12-51 mm bar, hex receiver with spring-lock safety.
• Super Knuckle 23 cm (9 in) adjustable arm.
• ¼"-20 male device screw.

Not included unless bundled: the VisionFrame 35 post or frame; the camera, lens, light, sensor, monitor, or controller; a camera-specific adapter plate; and cable strain-relief hardware.

Before ordering, confirm a 35 mm VisionFrame post, 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 you have (or are buying) a 35 mm VisionFrame post for the clamp to grip - this mount is not for 16 mm VisionGrid rail, 22 mm VisionGrid tube, or 3030 / 4040 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 - keep the payload light at this length.
• Weight or secure the post base, and re-check the clamp's grip on the post after loading - a tall freestanding frame can sway, and a clamp can creep down the post under load or vibration.
• For a released production line - not a prototype - use VisionCell, a SightLink E3040 retrofit, or a custom fixture.
