Crafted in the USA from a single piece of precision milled T5 aerospace aluminium alloy, the TetherBlock is lightweight yet exceptionally durable. It features multiple cable routing channels that can accommodate thick, medium, or thin cables, including USB, HDMI, or FireWire. Rubberised non-slip pads on the base help prevent the plate from shifting during use, while dual 1/4″-20 accessory threads provide flexibility for mounting non-Arca compatible tripod plates. The Tether Tools TetherBlock is a must-have accessory for photographers who shoot tethered, whether handheld or mounted on a tripod. Designed to prevent cable strain and protect your camera’s data ports, the TetherBlock secures your tether cable in place and eliminates the risk of accidental disconnection or costly port damage. Ideal for studio and on-location work, it ensures a more reliable and secure tethered setup. With its male 1/4″-20 screw mount, the TetherBlock attaches directly to the bottom of your camera and is compatible with both 1/4″-20 and 3/8″ tripod mounts. For photographers using Arca-style tripod heads, the TetherBlock Arca version is recommended. The TetherBlock was developed by professional photographer David Blattel to address the common issue of dislodged cables during tethered shoots, and remains an essential tool for safeguarding your gear and maintaining workflow continuity.
