Rotating and rotating/tilting complete arms have handles to lock joints into position. For the rotating/tilting complete arm, mount the base to a bench or wall and secure the object you want to position to the attaching end.
Any-which-way complete arm bends and stays in position. It does not have a ball; a screw-on base (sold separately) must be secured to the attaching end to attach to a connector.

Use these inserts in hitch-ball connections for towing. They fit into a receiver that's attached to a vehicle. Maximum trailer weight is the total weight being towed. Vertical capacity (also known as tongue weight) represents the weight of the load on the hitch ball.
Combination ball/eyes give you the versatility of mating with a drawbar ring or hitch-ball coupler. The higher capacity is for the drawbar ring; the lower capacity is for the hitch ball.
Multi-size hitch balls provide three sizes in one. The larger hitch ball sizes have higher capacities.
Height adjusting multi-size hitch balls provide three sizes in one and can raise or drop the ball to the height that works for your trailer. The larger hitch ball sizes have higher capacities.
Eyes and combination ball/eyes with multi-size hitch balls allow for more range of movement than ball hitches, making them good for use on uneven surfaces. Since they can also tow higher capacities than ball hitches, they’re often used to haul large items.
Use hooks and multi-size hitch balls with hook to attach towing chains, straps, or cable to haul heavy objects, such as vehicles.

Calibration Kit for Metal-Detectable Plastics

Made with metal additives, these balls test the sensitivity of food-processing metal detectors. They’re often used to calibrate metal detectors to find metal-detectable plastic tools that have fallen into a batch. To calibrate your metal detector, run different balls through the line—the smaller the ball, the more sensitive the detector must be to recognize it. Since they’re spheres, their orientation won’t affect a metal detector’s ability to register them. These balls help you comply with Hazard and Critical Control Point (HACCP) programs for food safety. They’re FDA compliant for direct contact with food. Balls are autoclavable, so you can sanitize them with steam.
