2PCS 10x11mm Length 1Meter Black Plastic Open Type Cable Wire Carrier Drag Chain Towline R18 for 3D Printer and CNC Machines (10mmX11mm-Outside Open)

This cable chain worked well on my Frankenstein diode laser. Easy to cut and assemble. I've never had cable chain that opened to allow the insertion of wiring and piping before, pretty cool.

Good quality. Pretty easy to work with. Hand surprisingly durable. Didn’t break when I thought it would. It is a little larger than I wanted though.

Sturdy,works well.

Solid design and build quality with a nice smooth movement. The radius seems fine, for my needs. Not much else to say about them. Have not installed yet but I see no issues with their use. I would certainly buy these again in the future. Have purchased other brands that do not lay flat, these do. I searched for a while to find a decent drag chain. They are more important that they seem. Having a failure with automated equipment can lead to unthinkable damage to people and surroundings. A laser can get stuck, and burn down the buildiing. A CNC can rip itself apart and cause some real damage. Having cable management that is secure and trustworthy is paramount. I absolutely TRUST these.
