Clean, Versatile, & Simple

Enjoy the sleek look of cable railing without all the bulky, external hardware. Cable Bullet tensioners fasten to the inside of the post, tightening cable runs out of sight. The universal tensioning mechanism means no more tensioning & non-tensioning ends, staggering cables around corners, or separate kits for level & angle runs. It's the same interchangeable hardware for all railing sections - simple, right?

Cable Bullet metal post tensioners feature a finer machine thread ideal for steel or aluminum post walls. They're designed to easily fit our Signature series tensioner posts. The versatile design and minimal profile also make them a popular option for custom metal railing.

Enjoy a Cleaner View

Tensioning happens inside your posts, so all you see is the slim 1/4" profile of the tensioner. No turnbuckles or extra hardware!

Simple Tensioning

Easily tighten your cables without the extra hassle. This turnbuckle alternative makes the tensioning process so straightforward, anyone can do it!

High-quality materials

Built for strength & durability with marine grade T316 stainless steel, so you can be confident your railing is built to last. Tensioners are corrison resistant, perfect for both indoor & outdoor projects.

Universal Hardware, Less Complexity

Say goodbye to complex systems with different ends & uses. Cable Bullet tensioners use the same mechanism for straight, sloped, & angled runs.

Low Maintenance

Spend less time treating your railing & more time enjoying the view! Unless in a coastal environment, cable railing only requires a quick cleaning once a year.

Ideal for Steel & Aluminum Posts

Metal tensioner kits thread easily into Signature series posts. The finer machine thread and minimal profile also make them a great option for custom metal railing.

Versatile for your project

Because all our tensioners feature the same hardware, you can mix & match metal kits with ones for wood or sleeved posts and masonry columns.

U.S. Made

All components of the wood tensioner kit are proudly designed and made in the USA.

What's Included in a Kit?

Each cable rail tensioner kit includes all the fittings necessary to anchor and tension a single cable end:

    • (1) Cable Bullet for metal posts
    • (1) Crimp sleeve
    • (1) Lobed washer
    • (1) #10-32 x 1/4" half dog socket set screw
    • (1) Rubber o-ring (pre-installed)
      As the Bullet is advanced into the metal post, the o-ring acts as a cushion, allowing the installer to adjust the alignment of the set screw location relative to the post. Once set, the o-ring also serves as a lock washer, tensioning the Bullet to it's preferred position.

How many kits should I order?

Every cable run will require 2 tensioner kits, 1 for each cable end. To calculate the number of kits required for your project, simply add up the number of terminal cable ends along your railing. Use the same kit on level or sloped runs up to 20 feet long.

What cable should I use?

All Cable Bullet cable railing kits were designed exclusively for use with 5/32" cable. If your project includes sloped or angled rail sections, we highly recommend using 7x7 cable. The additional flexibility of the 7x7 cable braid allows for cleaner lines and tighter angles between staggered posts.

How much is my project going to cost?

Overall costs will vary widely by project design and layout. The average cost per foot will fluctuate based on span lengths, rail height, and handrail selection. A base estimate for projects using tensioner kits for metal posts and Signature series railing:

$75 - $80 / linear foot of railing*

*Average calculation is based off a standard 12' x 24' deck, with approximately 50'-60' of 36" high railing, 6' average post spacing with spacer bar kits. Tools not included.
