The Tether Tools TetherBLOCK takes strain off your USB, FireWire, or HDMI cable to prevent damage to your camera’s port due to incorrectly angled detachment of wires. This plate can be mounted on to 1/4-inch and 3/8-inch male tripod threads. It has two 1/4-inch-20 threads for attaching your camera. The non-slip pads and stainless steel screw keep the plate in place, thus securing camera mounting. It is made of top-quality aircraft aluminum with an anodized finish for reliability and durability. The plate, thus, helps you focus better whether you are shooting handheld or with a tripod.
