Railing That Won't Clutter Your View

Enjoy a clear view from your deck with the sleek profile of cable railing. Cable Bullet tensioners tighten cables inside the center wood post without the bulky, eternal hardware. The same tensioner is used on level and angled rail sections, and you don't have to stagger or off-set cable runs around corners. Interchangeable and versatile for a simple, stress-free installation.

Each tensioner kit includes a pre-fitted rubber o-ring and a steel ring to cap the hole through the post sleeve. It protects the sleeve and has a clean, finished look once installed.


Simple Tensioning

Easily tighten your cables without the extra hassle or complexity. Each cable end tensions separately, and the process is so straightforward, anyone can do it!


Precision Design

Designed specifically for sleeved posts with modern aesthics in mind. There's no need to drill through the backside of your posts, and the sleeve stays protected from hardware scrathes.


High-Quality, U.S. Made

Each tensioner features quality U.S. craftsmanship, so you can be confident your railing is built to last. Machined from marine-grade T316 stainless steel and corrosion-resistant for both indoor & outdoor projects.


Enjoy a Cleaner View

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

Product Details

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

(1) Cable Bullet for wood posts

(1) Crimp sleeve

(1) Lobed washer

(1) #10-32 x 1/4" half dog socket set screw

(1) Rubber o-ring (pre-installed)

(1) Steel ring (pre-installed)
The rubber and steel rings cap the slightly larger hole through the post sleeve and protect the sleeve from the cutting edge on the backside of the tensioner.

My Project

The sleeved cable rail hardware is available in three sizes with identical tensioning capabilities:

Standard 1-1/2" Bullet:For thinner sleeves that are flush to the post.

XL 1-7/8" Bullet:Has a longer shank and additional threads to pass through the cavity in large sleeves and make full contact with the center post.

XXL 2-3/4" Bullet:For maximum length when drilling through larger post sleeves.

Order the size that's appropriate for your vinyl or composite sleeve by measuring the distance from the face of the sleeve to the center post.

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.

All Cable Bullet cable railing kits fit exclusively 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.

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 sleeved posts:

$45- $50 / linear foot of railing*

*Average cost is based on a standard 12' x 24' deck with one short set of stairs and approximately 50'-60' of 36" high railing, 6' average post spacing with spacer bar kits. Tools not included.
