The Tether Tools Jerkstopper A Clamp (2″), model JS080A2, is a specialized cable management device designed to prevent accidental cable disconnections and damage to equipment ports. It is a simple but essential tool for anyone shooting tethered or using electronic equipment in a dynamic environment, such as a studio or on location.
How it Works:
The core concept is to create a secure anchor point for your tethering or power cable, thereby removing any stress or strain from the delicate ports on your camera, laptop, or other device. If someone trips over the cable, the force is absorbed by the clamp, not by the equipment.
Key Features and Specifications:
2″ Jaw Opening: The "2″" in the product name refers to the maximum jaw opening of the A-clamp. This allows it to securely attach to a wide range of objects, including tripod legs, light stands, studio rigs, tables, and shelves.
Integrated Jerkstopper: The clamp features a built-in, flexible Jerkstopper cable retention device. The cable is threaded through this component, which holds it firmly.
Cable Diameter Compatibility: It's designed to work with most standard cables used in photo and video production, supporting cable diameters from 3.5mm to 8.5mm. This includes USB, HDMI, FireWire, and standard A/C power cords.
Rotational Design: The Jerkstopper part can be rotated on the clamp's handle, allowing you to adjust the direction of the cable's path to suit your specific setup.
Protective Jaws: The clamp's jaws have a non-reflective, polyvinyl coating. This protects the equipment it's clamped to from scratches and also helps to minimize glare in a studio setting.
Durable Construction: The clamp is built for pressure clamping, providing a fast and secure grip. Its all-black, non-reflective finish is ideal for professional use.

How to Use the Jerkstopper A Clamp:
Clamp to a Stable Point: Attach the clamp to a secure, stationary object near your shooting setup, such as a tripod leg, light stand, or the edge of a table.
Thread the Cable: Route your tethering cable through the opening of the Jerkstopper.
Create Slack: Ensure there is some slack in the cable between the clamp and the port on your device. This slack is crucial, as it allows the clamp to absorb any tension.
Connect Your Device: Plug the cable into your camera or computer.
By using the Jerkstopper, you can work with peace of mind, knowing that your expensive gear is protected from accidental disconnections and damage.
