18mm Inner Height Drag Chain, Side-Open Plastic Cable Carrier for CNC Routers & Milling Machines (Includes 18x37mm & Multiple Sizes)

Convenient Side-Open Design (Snap-Open Crossbars): Features a bridge-type structure where each individual crossbar can be unbuckled and opened from one side independently, allowing for effortless cable insertion and maintenance without disassembling the chain.

Heavy-Duty Reinforced Plastic: Molded from premium nylon engineering plastic, delivering exceptional mechanical strength, wear resistance, low-noise movement, and long-term durability.

Tangle & Wear Prevention: Effectively isolates and protects internal wiring from mechanical friction, snagging, and excessive bending stress during continuous reciprocal motion.

Construction of The Drag Chains

This is the largest model in the Mini series, suitable for devices that require slightly thicker cables yet remain constrained by limited overall space. Constructed from flame-retardant, V-0 rated PA66 material, it is self-extinguishing upon removal from a flame—making it ideal for electronic equipment with stringent fire safety requirements.
