Camera data ports are fragile and expensive to repair. When shooting tethered in studio or on location, a trip or tug can cause your tether cable to become dislodged or cause serious damage to your camera’s data ports. The TetherBlock™ is a must-have for photographers shooting tethered both handheld or using a tripod.
The TetherBlock™ is designed to prevent accidental removal of a cable from your camera’s data ports by snaking a USB, FireWire, or HDMI cable through one of TetherBlock’s™ three channels. A 1/4″-20 slotted screw attaches the plate to the camera, and can be tightened with a screwdriver or coin.
From there, either shoot handheld or attach the TetherBlock™ to your camera’s tripod mount and you’ll be able to shoot tethered to a computer without fear of your tethered cable becoming unplugged. TetherBlock™ Arca simply connects to any Arca compatible tripod head and TetherBlock™ mates with your favorite plate to connect to any existing tripod head.
Easy to mount, the TetherBlock™ and TetherBlock™ Arca have a 1/4″-20 male thread to attach directly to the bottom of your camera.
This Arca-style connection is compatible with all Arca compatibile ballheads with the standard 35mm wide connection. This is not compatible with the Arca-Swiss Monoball Fix Series. The bottom of the TetherBlock™ Arca features two 1/4″-20 female threads.
There is not a centered 1/4″-20 female thread on the TetherBlock™ Arca, so if you need to mate this to a non-arca plate, we recommend the non-arca TetherBlock™.
Constructed in the USA from a single piece of precision milled T5 aerospace aluminum alloy, the TetherBlock™ is extremely durable while remaining lightweight and is covered by Tether Tools Lifetime Warranty.
