Dome rooflight fall-through protection type LK-DDN

The manufacturer-independent fall-through protection for all upstands

VELUX Commercial presents an innovative solution for the retrofit-capable fall-through protection of dome rooflights: LK-DDN (dynamic fall-through protection net). The net construction with a unique combination of an energy-absorbing mounting console and an objective test method immediately provides a number of advantages.

The net is suitable for kerbs from all manufacturers, dimensions, materials and geometries – and all this regardless of whether the dome rooflight is used for pure lighting or for ventilation and smoke exhaust. It is BG (German Employee´s Liability Insurance Association) tested, certified and, due to its objective load-bearing capacity test, guarantees maximum safety for work on flat roofs.
The LK-DDN is available directly from stock as a retrofit set in five different dimensions. It can be cut to size on site and therefore always fits perfectly. In addition, it is the only fall-through protection system that secures itself. The innovative fastening mechanism with two interlocking elements is not only simple to assemble, but also tensions the net automatically when it is screwed together. With this retrofittable fall-through protection, you can thereby benefit from maximum safety and a high degree of flexibility.
