No, this isn't a tank tread, this is a 0.5m long Cable Carrier with 10x15mm bits composing its main body and two screw fasteners at each end for efficient mounting. Sometimes called a "drag chain," each carrier can be used in projects with a large number of moving parts to protect internally installed cables, pipes, or tubes so they can be bent and moved while remaining protected. Cable carriers can most commonly been found in 3D printers and CNC machines but they can be used in any situation where you need cables or tubes to bend without risk of them being damaged or wearing out prematurely.
This specific cable carrier offers inner dimensions of 10mm（height）by 15mm（wide）, an outer width of 22mm, and a bend radius of 20mm. Additionally, these carriers are thin enough to fit into an Actobotics channel, making custom slide machines or other projects even easier to manage. Much like a chain, individual links can be added or removed to make custom lengths.
