<p>A scaffolding side frame (10) has at least one generally horizontally extending tube (11), a pair of vertically extending side tubes (12) depending from the horizontal tube, and four fastening members (17), one adjacent each corner of the frame, for securing the side frame to a respective adjacent structural element of an associated scaffold structure so that the upper part of the side frame provides a safety rail for an operator standing on a support platform of a given level of a scaffolding structure and the lower part of the side frame extends below the support platform of said given level of the scaffold structure. The two lower fastening members are hook-shaped and the hooks have a fastening latch (19). The latch (19) is displaceable to a retracted position in which the hook can be snapped over the adjacent structural element of the structure. The side frame (10) is mountable in its operating position by an operator holding the lower part of the frame whilst standing on a support platform of a level of the structure below said given level and engaging the fastening members (17) with their respective adjacent structural elements so that the side frame immediately becomes and remains a full load transmitting structural part of the associated scaffold structure. The configuration of the fastening latches (19) of the lower fastening members (17) preventing the operator disengaging the lower fastening members when stood on the support platform of said given level of the scaffold structure.</p> |
