Hidden Hardware to Maximize Your View:

  • DIY-friendly installation
  • Crafted from 6061T6 aluminum
  • Compatible with Signature Series posts and custom metal posts
  • Concealed, patented hardware to maximize your view
  • Effortless tensioning with just one set screw
  • Anodized with a type III hard coat for a sleek, jet black finish
  • Designed for 5/32” cable
  • Get the right fit—Tensioner packs pair with 36" or 42" Signature Series posts. A pair of end posts will need (1) pack of 22 or 26 tensioners, while a single 2-way or corner post will need (1) pack of 22 or 26 each.

A note about black finishes and colorfastness: We use an architectural hardcoat anodized finish on our tensioners and post tops. That anodized finish has been tested to the equivalent of 8 years of UV exposure with excellent color fastness to maintain its appearance. Pairing black anodized tensioners with black oxide stainless steel cable is a popular choice for achieving a darker, more understated look, but it’s important to understand the limitations of black oxide. We permit black oxide cable for outdoor use, but we do not recommend it for coastal or high‑salt environments. The black oxide finish will naturally fade with UV exposure, and while occasional oiling can help slow that process, it is not designed to offer the same long‑term color stability as a coated or anodized finish. With cable, this aging is generally acceptable, the natural texture and depth of the strands allow it to continue looking good even as the black softens.

My go-to cable railing tensioning system

"I'm a metal fabricator and these are my go to tensioners for cable railing systems. They're easy to install, durable, and not nearly as obtrusive as the conventional turnbuckle style tensioners and much less expensive. I generally integrate the tensioners into custom posts but have used their modular railing system with minimal complaints too. This is what I recommend if anyones looking for a cable railing"

Quality at its best

"5 Star product and service"

Glen D. (5/5)

Needed a replacement for a faulty part.

"Easy"

Glen D. (5/5)

Disappointed

"The new black tensioners for metal posts are now manufactured from aluminum as apposed to stainless steel, my crew did not rate the assembly as good and question the longevity. You would expect the price to be cheaper now that they are aluminum,"

Matthew C. (2/5)

Excellent product

"Excellent product"

Michael G. (5/5)

It ruined several pieces of

"It ruined several pieces of cable because the length I cut was longer than it should. There should be more emphasis in the videos and instruction on this part of the installation process, because the margin of error is very small. Now I won't make that mistake again. I wasted time, cable and accessories. The job is finished and it looks great."

"Time consuming but nothing good happens quick. Great product!!"

Q&A

What tensioners would I use for a wood post with an aluminum sleeve?
Great question, Brandon! It will probably depend on the thickness of the metal sleeve. I would recommend contacting our cable railing experts so they can get more details on your specific scenario and give you the best recommendation. You can reach them by phone at (574) 742-2737 (available Mon–Fri 8:30AM–4:30PM EST) or by emailing info@cablebullet.com.
How many tensioners come in the tensioner kit for $10.95?
Hi, Brian! We sell our tensioner kits individually for the most project flexibility. Each tensioner kit comes with (1) cable tensioner, (1) crimp sleeve, (1) lobed washer, and (1) set screw. Each run of cable will need one tensioner kit on each end.
