How to use Loos PT-01 Tension Meter
Cable tensioning using the Loos PT-01 Tension Meter
While the cables in your railing shouldn’t be tight to the point where they bend your rails or posts, they absolutely cannot be too loose. Loose, sagging cables have poor atheistic qualities, but more importantly, they’re not up to cable railing code requirements. International residential codes specify that a four-inch diameter sphere shouldn’t be able to pass between vertical or horizontal cables. This is for safety reasons, preventing small heads and shoulders from being able to squeeze through the space. Loose cables let children stretch them and widen the space between cables to crawl or stick their head through. Even if no children are in the home, maintaining enough tension to prevent cables from moving or stretching is still a requirement to pass a building inspection.
