Cable Railing Hardware, 20 Pcs Invisible Cable Railing Kit/Turnbuckle for Wood & Metal Post for Stair Deck Railing System Fits 1/8 Stainless Steel Cable, T316 Marine Grade, Challcrea

I wish I had seen reviews prior to my purchase, and more importantly, waste of time installing. I propose if you were doing a steel rail, and the interior ferrule was exposed, you could grab with a chan-el-lock or something to hold the cable from twisting while you tighten, of course probably marring the surface while doing so, or just move on to another option. These were HORRID in wood post... Only purchased for the clean and hide-able ability, which at first looked fantastic. But upon working to tension these, lets just say bad bad bad. Dont get these.

My initial assessment is positive, time will tell if it's durable. The design is nice and clean

When going through a 6” post it’s impossible to get them tight. As soon as the cable takes tension it will no longer turn no matter how much threads are left. Probably works ok on a smaller post.

Bought these to fix some cable railings that broke. They were a perfect match. Easy to work with but I bought a crimper to crimp them.
