Aweking 15 x 20 mm (Inner H x W) R28 Semi Enclosed Drag Chain, Cable Carrier Track, Wire Protection Chain Connector 39.3inch/1M for 3D Printer, Industrial CNC, White Plastic (Inner Side Open)

• 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：279g/9.84ounces, Bending radius: R28,Internal Size :15 x 20mm/0.59inch x 0.79inch(H*W), External Size : 20 x 30mm/0.79inch x 1.18inch(H*W),Total bending height：76mm/3inch, 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 specification of 15x15 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.
