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 mates with your favorite plate to connect to any existing tripod head.

Easy to mount, the TetherBlock has both a 1/4"-20 and a 3/8" tripod thread, allowing it to be mounted directly onto a tripod or head.

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.



  • The bottom of the TetherBlock features both a 1/4″-20 and a 3/8″ female tripod thread, allowing it to be mounted directly onto a tripod plate or head. If you are mating it with your tripod plate, you will be able to center your plate on the TetherBlock giving you a secure connection.
  • Use to secure any cables that connect to or near your camera for use in photography, video, audio, etc.
  • Compatible to all cameras with a female 1/4″-20 mount on the bottom.
  • What’s Included: One (1) TetherBlock in Graphite.
