Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.

All accessories include the necessary hardware for attaching them to arms.

Clamp-on bases have two arm attachment locations. Place arms straight or at a right angle from the clamping screw. Clamp-on bases with a rubber V-block can be mounted to rounded surfaces such as pipe and railings.

Spring clamps with three attaching end mounting holes can be mounted parallel or perpendicular to your positioning arm. Spring clamps with a 4 1/2" reach clamp further into a workpiece than other spring clamps.

Three-finger clamps have bent fingers to hold workpieces that are hard to grip, such as beakers, flashlights, and webcams. A rotating position lock lets you rotate these clamps on your positioning arm. Secure clamps in place with the included locknut.

Bend these arms to hold small equipment such as lights and microphones in almost any position.

Adjust the flexible ball-and-socket segmented arm to nearly any position and lock in place. A heavy base adds stability.

Holders with a granite base have an extremely tight flatness tolerance. Their flatness gives you an accurate reference for inspection work and lets you move workpieces in and out smoothly. These holders have a fine-adjustment clamp to position indicators at precise angles.

Position the flexible ball-and-socket segmented arm around obstructions and lock in place with a lever. The vacuum base provides stability on granite plates and other nonmagnetic surfaces.

A flexible ball-and-socket segmented arm adjusts to nearly any position and locks in place with a lever. The base is comprised of adjustable magnetic pins which allow it to conform to any shape and grip most metal surfaces. It has a magnetic-release switch for easy setups.

Holders with V-grooved base can be mounted on both curved and flat surfaces.

Holders with fine-adjustment base or clamp give you more precise control over positioning.

Often used where space is tight or there’s not much of a surface for mounting, the clamp on these indicators fits where a weighted or magnetic base can’t. The clamp also gives you the option to directly mount these indicators to a machine or the piece you’re measuring. With the ball-and-socket segmented arm, you can adjust the indicator to nearly any position to keep it from obstructing what you're measuring. Pull the lever to lock the arm in place when you're done. To measure objects, these indicators have a spring-loaded plunger that retracts and extends as the surface varies. It’s easy to see how much a measurement increases, since the dial is continuous and numbered clockwise around the face. Adjust the tolerance pointers to mark measurements that fall outside your limits.

Indicators with a plier clamp work on most thin, flat surfaces.

Indicators with a C-clamp apply less pressure than indicators with a plier clamp, so there’s less risk of damaging a workpiece.

With adjustable magnetic pins that conform to any shape, the base on these variance indicators mounts securely to uneven surfaces. The ball-and-socket arm is highly adjustable and locks in place with a lever, so it holds the indicator in almost any position. For quick dismounting, the base has a magnetic release switch.

A spring-loaded plunger extends and retracts to measure objects. The measurements are displayed on an LCD screen. Start measuring at any point by pressing the zero-set button. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off.

All can send data to your computer using a USB cord (sold separately). They have SPC data output to wirelessly transfer your measurement data to your device with the push of a button. You'll need a data transmitter/receiver set (sold separately). Indicators with Bluetooth send measurement data to your device wire-free and without an additional device.

IP67-rated indicators seal out coolant, water, and dust, so you can take measurements in dirty machining environments.

Tolerance checking indicators inform you when an item falls outside your set measurements.

Bend and flex the arm of the base to position your indicator—these holders have ball-and-socket segments that lock in place with a lever. The base is magnetic and has a V-groove on the bottom for a solid mount on flat and curved metal surfaces. Flip a switch to release the magnet.
