Its called a "cable tensioner eyelet."

Always pleased to learn about new hardware.

Before I sold my construction company, I had a subscription to "Sweet's Catalog." I regularly received manufacturers' product sheets from Sweets for almost every construction related product available in the U.S.

Each time I received a new batch of product sheets, I would sit down and review the new or improved items, log titles of those that were of interest and then file all of them in three ring binders. I had thousands of those product sheets.

I did that with NASA tech briefs.

Some were exeptional.
