Surface Mount Cable Railing Features

Cable Railing With View

Preserve your view: An overall view of decking fitted with 5/32 inch (4 mm) deck rail. The cables give a stylish finish and provide an unimpaired view from the deck.

Stainless Steel Cable Railing Running Through Intermediate Posts

It is possible to run cables up to 50 ft passing through any intermediate posts to minimize the number of cables you'll need.

42 Degree Articulation

Our ball and socket design is ideal for shallow angles with an articulation of up to 42 degrees, perfect for stairs and inclines.

DIY Installation Advice

Cable Railing Installation

Before installation we advise you consult with your local building department as building code requirements vary by state, county or city.

We recommend you plan your project in advance to ensure you have the correct number of posts, cable and fittings, remember to take into consideration end post and corner post termination clearance and position.

For end posts we recommend using 4 or 6 inch posts to give a secure and strong fixing point for your cable ends.

Stainless steel cables should be spaced 3 inch intervals.

Vertical posts should be spaced at recommended 5 ft intervals (to a maximum of 6 ft 5 in.) apart to ensure a strong frame.

Measure twice, cut once!

Please be as accurate as possible.

Each cable has an adjustment of plus or minus 0.7 inch (20 mm).

Where can I mount my balustrade sockets?

This deck balustrade cable system is suitable for flat mounting onto either wooden posts or masonry wall surfaces using a 3 inch countersunk wood screw (supplied).

Note : when mounting onto masonry surfaces please drill a hole and insert a plastic wall plug before fastening. If a wall is particularly brittle or old - a chemical resin may be applied to further strengthen the hold.

1. Getting Started

It is a good idea to layout your design onto the relevant surface with a pen or chalk prior to drilling any holes.

Layout Your Project

2. Drill Pilot Holes

The 3" wood screw allows direct installation into hardwood timber (such as oak) or, if combined with the correct plastic plug, it is attachable to almost any masonry surface.

Drill Pilot holes

3. Mount Hubs into Position

Using a screwdriver fix the surface mounting hubs using the 3" wood thread screws.
Tip: Position the opening facing downwards for a better final look.

Mount Hub into Position

4. Prepare Pre-Fixed Ball End

Starting with the pre-fixed tension ball end, screw out the ball end to reveal approximately 0.7 inch (20 mm) of thread, you will need this to apply your final cable tension once installed.

Prepare Pre-Fixed Ball End

5. Mounting Pre-Fixed Ball End

Place the pre-fixed tension ball end into the mounting hub.

6. Mark Cable for Cutting

Pull the cable over to the other fixing post and align to the wrench flat of the DIY compression fitting.

Mark your cable ready for cutting with either a pen or chalk.

Note: The stand off from the mounting hub is 1.18 inch (30 mm).

7. Cut Cable

Cut your cable to required length, we recommend using a set of good cable cutters to give you a neat and tidy cut.

Remember - measure twice, cut once! Please be as accurate as possible.

Each cable will have an adjustment of plus or minus 0.7 inch (20 mm).

8. DIY Compression Fitting

You are now ready to attach the self-assembly end fitting.

The first step is to dismantle your DIY compression fitting - Simply unscrew the nose piece.

9. Thread Nose Piece onto Cable

Taking the blank cable end place the nose piece over the stainless steel cable (ensuring the thread end is towards the end of your cable).

10. Thread Cone onto Cable

Thread the cone onto the cable and push into the threaded cone chamber.

11. Place Ball End onto Cable

Take the stainless steel body and push onto the cable, eventually bringing the three component parts together.

Turn in opposite directions to thread them together.

12. Secure Ball End Fitting

Using a pair of 8mm and 9mm wrenches, screw the two sections together until tight.

13. Mounting Ball End Fitting

Insert the DIY ball end into the fixing hole of the hub.

Note: if you require more slack in your wire to insert the DIY end simply return to the fixed end ball and unscrew to expand to the required length.

14. Tension Cables

Returning to the pre-fixed ball end, simply screw the thread in to achieve the desired cable tension. Once you have achieved this, lock the nut into place using a 9 mm wrench (metric).

It is important that the cable is not allowed to be twisted.

Tensioning Sequence

Adding Cable Tension

To tension the cables, we recommend starting from the center and working out (see diagram below). Do not fully tighten individual cables as this will create uneven tension throughout your system, just tighten enough to hold in place. Once all your cables are installed, tighten each cable in turn by slight increments to achieve a solid and fully secure finish.
