The dimensions of the track: Length: 155mm Width: 25mm and a thickness of 4 mm. As you can see with reference to the photos, I have an iPhone 6 (not 6 plus) mounted on the right side of the accessory rail. The smartphone is in a bolted aluminum housing which is why it is much larger (88mm) and is held by a "Shoulderpod S1 Professional Smartphone Rig, Tripod Mount" (here at Amazon available). On the left side of the accessory rail I have a Knog Qudos Action Hightech Power lamp mounted; This ensures even in complete darkness enough light to even be able to make videos at night. This compilation comes with me usually at Demos for use. The lamp and Smartphone enclosures are protected against water and dust. In the middle of the accessory rail a further bore is eg to attach a tripod. Also worth noting that the two screws have below each incorporated another thread, so that other components could also be mounted here. The rail is high-quality!
