These are the brackets I designed for my SO3 XXL and [Uxcell R55 drag chain brackets.](https://www.amazon.com/uxcell-Plastic-Cable-Carrier-Chain/dp/B01LXNJ7NI) My HDZ is the first gen version, so the bracket for that one will have to be redesigned. I don't have the newest version, so you'll have to do it. There is hardware that needs to be purchased. I picked it up from McMaster-Carr: 02 - 92510A661_ALUM UNTHRD SPACER 08 - 92095A225_18-8 SS BUTTON-HEAD SOCKET CAP SCREW 16 - 93475A240_TYPE 18-8 STAINLESS STEEL FLAT WASHER 08 - 93625A200_TYPE 18-8 STAINLESS STL NYLON-INSERT LOCKNUT 02 - 91525A321_TYPE 316 STAINLESS STEEL FLAT WASHER 05 - 92095A214_18-8 SS BUTTON-HEAD SOCKET CAP SCREW 34 - 92210A112_18-8 Stainless Steel Hex Drive Flat You will need to drill and tap your aluminum extrusion to mount the brackets with the #4-40 screws.

I also designed some brackets for the smaller drag chain that came with my first SO3, and those will be linked shortly.
