Class 1 low voltage wiring in wall

[rimrock]

I am looking for an approved method to run class 1 low voltage wiring in a wall from jbox to jbox. What kind of cable and what kind of cable clamps are approved?

I have searched unsuccessfully for rated NM cable that contains just two 16 or 18ga. conductors. I've seen the MC luminary cable that contains two 14ga. conductors and two 16ga. low voltage wires (http://www.afcweb.com/mc-metal-clad-cables/mc-luminary-type-mc-pcs/mc-luminary/), but this is a 3-way circuit so I need three 14ga. conductors. I would also rather not use MC cable unless it is my only option.

I did find a non-metallic wire sheath with a "UL Recognized" rating (https://www.grainger.com/product/TECHFLEX-Expandable-Braided-Sleeving-1UXW6), so I could make my own cable from 16 ga. THHN wire, but would that be acceptable?

The rest of the installation is complete: there are 10 ceiling boxes connected by conduit, for dimmable LED lighting. I just need to run the wiring to the dimmer switches.
