A Polished Finish in One Simple Turn

The domed silhouette brings a tailored, bespoke finish to hardware moments that often go unnoticed. I love the subtle gleam of zinc-plated steel—it tidies up exposed threads with a refined gesture. Style them on visible furniture joints or open-shelf brackets for a crisp, intentional detail. An elegant essential that quietly elevates everyday construction.

Inputs and outputs not as advertised!
The inputs weren’t big enough for true 0 gauge wire and outputs were too small for true 4 gauge wire. As someone with a lot of mechanical background I was able to make it work using 0 to 4 gauge adapters and a drill had to bore the outputs to get the adapters to fit. Dont buy if not mechanically incline!

Not for 0 or 2 gauge wire.
The input on the 3 way I got is only big enough for a 4 gauge wire and doesn't have the reducer ferrules. The output is under sized where a 4 gauge might go in but not cleanly and also doesn't have the ferrules. The 4 way I got does accept a 0 gauge in and has the ferrules and the outputs are larger with ferrules.

Wasn’t even close
I really wanted this to work as advertised but unfortunately it was not even close to being able to fit the wire sizes it claimed to be able to.
