摘要

The work protection fence has vertical assemblies, fixation units and a few telescopic doorjambs for fixed on consecutive vertical covers. The external and interior profile is provided, which has a longitudinal zone in the shape of omega or dovetail, and carriers of ceiling that delimit the longitudinal relative displacement of the profiles. A T-shaped section that crosses horizontally the vertical covers to different height forms a tightening system. The ends are mounted with a safety nut.
