Existen también sistemas que fijan tanto el borde superior como el inferior de la red, con distancias menores, consiguiendo que en caso de caída, esta se produce desde alturas muy reducidas.Currently, there are various systems of placement of protective nets, fixed to the pillars of the structure, and hung from them, to very low levels, which the accidental fall is dangerous even when the aforementioned network exists. There are also systems that fix both the upper edge and the lower of the network, with smaller distances, getting that in In case of fall, this occurs from very low heights.

Estos sistemas, tienen sin embargo, algunas carencias, en cuanto a la protección en las zonas de las esquinas, que no quedan protegidas, o al menos con huecos en los que posiblemente puedan caer los operarios sin protección de red. Igualmente, existen casos, en los que el pilar al que se fija la red, no está exactamente a nivel con la superficie de fachada, sino interiores, con lo que la sujeción de la red a estos pilares no es posible, al menos que parte de la red quede apoyada sobre el forjado, disminuyendo la superficie elástica que protege cualquier tipo de caída.These systems, however, have some lacks, in terms of protection in corner areas, that are not protected, or at least with holes in which Operators may possibly fall without network protection. There are also cases, in which the pillar to which the network, is not exactly level with the facade surface, but interiors, so that the attachment of the network to these pillars is not possible, unless part of the network is resting on the forged, decreasing the elastic surface that protects any type of fall.
