Applications & Advice
- A top rail, capable of withstanding a compressive load, should be fitted to help absorb the considerable force exerted by the cables on the end posts. Without one the posts are likely to fall in and the cable to go slack.
- When drilling your posts and anchor points, the following sizes apply for the M6 system:
- Intermediate post clearance holes: wire size +1mm.
- Wooden anchor points - Pilot hole of 4mm
- Steel anchor points. Drill 5mm hole and Tap M6
- If tapping into metal posts, ensure the tapping tool is straight in all planes. The angle at which the 5mm holes are drilled into the posts is critical. Be sure that the measurement point and position of the holes are correct.
- When screwing the studs into the posts ensure the depth of the stud and the amount of visible thread is the same for each stud all the way down the post.
- For correct tensioning using 75mm (3 in) spacings the cable should not deflect to more than 100mm (4 in).
Note: You should always check with your local planning office to confirm that horizontal wires will be allowed

Technical Info
Building Regulations for Balustrade:
It is important to remember that where children under the age of 5 have access to the system, there should not be spacings between the cables which permit a sphere of over 100mm in diameter to pass through. Children should not be able to climb the balustrade. There are various solutions available such as installing posts that are angled inwards or that bend inwards at the very top or a vertical cable balustrade. Please see Approved document K, BS5395 Part 1 and BS6180 for further information.
When is balustrade required:
Domestic installations:
Balustrade should be installed where there is a drop of over 600mm, the height of installation on stairs should be no less than 900mm high and for high risk areas such as Juliet Balconies at least 1100mm.
Commercial installations:
Balustrade should be installed where there is a drop of over 380mm, but only if it is not part of stairs.
In the instance that there is a space beneath a stair or ramp less than 2000mm (or just over 6 and a half ft), some sort of guarding should be provided.
If a flight of stairs or a ramp is more than 2000mm wide, regulations state that they should be divided by a Balustrade.
All installations are required to be 900mm high on stairs and 1100mm, the exception of being when installed in front of fixed seating (in building such as cinemas, theatres and sports stadiums), the measurement is then lowered to no more than 800mm high, to make sure that sightlines are not obstructed in any way.
What spacings are required between runs of cable?
75mm (3 in) spacings are advisable with correct tensioning. Correct tensioning is achieved when the cables do not exceed deflection of more than 100mm (4 in).
How far apart should posts be installed?
We would recommend spacings between posts to be 1000mm to 1500mm. A top rail should be installed to help absorb the loadings in the end posts.
How long can each run of cable be?
We recommend spans to be 7-10mtrs in length at most to ensure you can adhere to the recommendations for deflection.
