I prefer the fork type, on the right, for this kind of cable, but don't like the cheesy rivet in the Spruce part. Don't know the material choice either. For a critical cable, I make a fork from 4130 sheet the same thickness as the slot is wide, and add a bar retainer with positive fasteners. An add-on for your existing bracket could be like the lower example. Craftsmanship counts; all edges smooth, break all corners, observe proper bend radius.
