TECNI® 6mm Commercial Balustrade System with Length & Terminal Options
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 M8 system:
Intermediate post clearance holes: wire size +1mm.
Wooden anchor points - Pilot hole of 6mm
Steel anchor points. Drill 7mm hole and Tap M8
If tapping into metal posts, ensure the tapping tool is straight in all planes. The angle at which the 7mm holes are drilled into the posts is critical. Be sure that the measurement point and position of the holes are correct.
For the best look, 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
