Vacuum Workholding Plates

Also known as vacuum chucks, these plates secure thin and flexible parts that can’t be held with vises or clamps for milling, drilling, routing, and finishing operations. Connect the system to your shop’s compressed air supply and it's ready to use. For applications requiring only part of the plate surface, use the gasket cord to seal off the area.

Risers


Riser	Riser with 1" Wide Step	Riser with 2" Wide Step

Risers, also known as vacuum pods, raise the workpiece off the vacuum table to give the cutting tool better access. Suction transfers from the table through the top of the riser, so to get a firm hold the workpiece must make contact with the full top length and width of the riser.

Retracting Stop Pins


Retracting Stop Pins with Pin Retracted

Retracting stop pins let you repeatably locate parts on your vacuum table. After positioning your workpiece against these pins, turn on the vacuum and the stop pins retract, dropping out of the way so the cutting tool has full access to the workpiece.

Side Stops

Side stops fit into the grooves of the vacuum plate to help you repeatably position material. They can be removed from the plate after the vacuum is turned on to give the cutting tool more access to the workpiece.

Ball-Grip Positioning Arms

Arm Built with Rotating Complete Arm

with Ball, Rigid Connector, and

Universal Mounting Plate

Ball-and-socket connections allow 360° positioning. Choose a complete arm or select a base, connectors, and accessories to build your own.

To ensure compatibility, select components that have the same ball diameter. Use reducing connectors (sold separately) to pair components with a 1 _1/2" ball diameter to those with a 1" ball diameter.

Vacuum-Mount Air-Powered Vibrators for Wet Materials

These vibrators attach more quickly than other vibrators by generating a vacuum instead of bolting or welding, so you can place them at the source of the blockage and quickly move them between bins. They're often used to dislodge sticky, caked-on materials from trailers, railcars, and hoppers. Bin wall thickness determines the force required to move the material in the bin. To select a vibrator strong enough for your application, find your bin's wall thickness in the table.

Wireless Charging Pads


	Style 3

Simply place smartphones on these pads to immediately start charging them—there’s no need to remove most cases or plug them into a charging cord. All pads are compatible with smartphones that have Qi technology, so they work with Apple iPhones made in 2017 or later and many Android phones, including the Samsung Galaxy S series. Often used on desks and other flat surfaces, these charging pads make it easy to grab your phone while it’s charging because you don’t have to unplug it.

Pads that are Qi certified meet safety, compatibility, and energy-efficiency standards set by the Wireless Power Consortium. They’re CE Marked, so you know they meet strict European safety standards. They’re also FCC compliant to meet regulations for electromagnetic interference.

A variety of USB cords and USB chargers are sold separately.

Style 3—Style 3 charging pads come with a mounting stand so you can install them on windshields or dashboards in a variety of vehicles. Adjustable clamps with silicon pads hold your phone in place while it’s charging, even when driving through turns and over bumps. These charging pads have a flat surface. A USB cord is included.
