Aweking 10 x 10/11mm (Inner H x W) R18 Bridge Type Drag Chain Cable Wire Carrier Protection Chain 39.3inch/1M for 3D Printer and CNC Router Mill,Black Plastic Nylon（Outer Side openable）

The Drag Chain consists of many small sections. It can be easily opened with a flat-head screwdriver and combined freely.Made of PA66 nylon, it's characterized by its aesthetic appearance, high gloss, odorlessness, as well as high tensile strength, impact resistance, and excellent wear and corrosion resistance.

Total Length : 1Meter/39.3inch，Weight：130g/4.59ounces Bending radius: R18,Internal Size :10x 10/11mm/0.39inch x 0.39/0.43inch(H*W), External Size : 15 x 16.5mm/0.59inch x 0.65inch(H*W),Total bending height：51mm/2inch, Package included:1 x Cable Drag Chain

Drag chains are designed to embed cables, oil lines, water pipes, and other conduits to serve traction and protective purposes. They help minimize wear and stress on cables and hoses, prevent tangling, and enhance personnel safety. These mechanisms find extensive applications in 3D printing devices, CNC machines, robots, automation equipment, firefighting apparatus, glass instruments, and more.

The drag chain's internal height is determined by the cable diameter (which should be less than 90% of the internal height), while the internal width is based on the number of cables (ensuring total width is less than 90% of the internal width). The bending radius of the drag chain is determined by the installation space.

When flat, the drag chain may slightly lift at the ends due to internal stress（Only the two specifications of 7x7 and 15x40 have obvious warping at both ends, and the others are almost flat. Please refer to the fourth picture when placing an order.）; when bent into a "U" shape, the longer section will flatten.
