Tensioned Wire Cable Balustrade systems - installation

How to install the S3i surface mount cable railing system

Prepare the surface

Measure out carefully ensuring that the sockets will be situated evenly on the surface. With timber it is advisable to drill a pilot hole prior to fixing. Masonry surfaces should be drilled and a plastic plug inserted for additional strength.

Mount the sockets

Once you have prepared the mounting point simply bring the socket to the surface and pass the stainless steel woodscrew through the centre of the socket and screw tight with a No.3 Posidrive screwdriver.

Attaching the cables

With the sockets in place simply clip the ball end into the socket.

Running cable rail through intermediate posts

The smaller, fixed end, of the wire assembly features a detachable ball. Once removed it reveals the slimmest part of the cable for passing through any intermediate posts.

The diameter of this fitting is 7mm - so you will need clearance holes of just over 7mm.

Adding tension to the cable railing wires

With the cables loosely in place at each socket, take one spanner and locate the spanner flats of the threaded fitting. Use the other spanner to hold the body and stop it, and the wire, rotating.

Twist the threaded part of the fitting to add tension.

Once tightened to sufficient tension, bring the lock nut up to the shoulder of the body.

How much tension should I apply to the deck cables?

There is no fixed rule here as there are many variables at play.

You are applying the tension by hand and can see and feel the results.

Take your time applying tension and keep an eye on what is happening. Keep going until you are happy with the tension.
