A structural support system, such as, a scaffolding or a falsework comprising verticals (10) and horizontals (40) connected at node sections (120) at the verticals (10), each node section (120) comprising a locking device for joining horizontals (40) and/or diagonals with bladed ends arranged at ends of the horizontals (40) and the vertical (10), where the locking device is a cup pair comprising a bottom cup (20) held at a position on the verticals (10) and atop cup (30) moveably arranged on the verticals (10), where bladed ends of the horizontals (40) or diagonals are configured to be locked by bottom cup (20) part and top cup (30) part, providing a rigid connection. That is characterized in that parts of the structural support system intended to be held at a position on the verticals (10) are held by using one or more fastening means (50) and corresponding hole(s) (11, 25) in the parts and the verticals (10), the fastening means (50) being rigidly fixed by screwing a headed bolt into the vertical (10), providing a compressive vertical load in vertical and/or horizontal direction capacity of the lower cup via the bolt.

A post for a temporary safety rail system comprising a base for reversible engagement with a floor, a rail holder to hold a rail in reversibly fixed engagement with the post and a plurality of components which are together operable to adjust the height of the post.

A modified scaffold component for use in modular scaffold systems allows securement to vertical uprights in a conventional manner and allows a work surface to pass over supporting uprights (if desired) to form a continuous work surface where securement of the modified scaffold component is below and does not interrupt the work surface.

A stepladder having a front side, a rear side and a top. The stepladder can include a conduit holder attached to the front side for holding conduit. The stepladder can include a first wire spool holder attached to the front side and a second wire spool holder attached to the rear side though which a conduit having a wire spool extends. The stepladder can include a hacksaw hook attached to the front side. A method for cutting a conduit. A method for using a hacksaw. A method for obtaining wire.

A connector for interlocking components of scaffolding or other supporting structures for building forms. The connector includes a body having an internal chamber bounded laterally by planar first and second surfaces. A lever is seated in the chamber laterally intermediate and in close fit with the planar first and second surfaces for inhibiting lateral movement of the lever. The lever is movable between a lock position and a release position. A spring is seated in the chamber laterally intermediate and in close fit with the planar first and second surfaces for inhibiting lateral movement of the spring, the spring for biasing the lever into the lock position.

A coupler device (10), for connecting two overlapping building elements (V, H) at substantially right angles. The device includes a main body (11) and two hingedly attached gate elements (12, 13) extending at perpendicular and offset axes from the body. Each gate element respectively includes an associated tightening mechanism, e.g. a rod (17, 20) with threaded end engaging with a nut (19, 22), for controlling closing force toward the main body and clamping a building element. In use, the respective tightening mechanisms (e.g. nuts on threaded rod) are accessible from substantially the same direction relative to the main body and not obscured by the two overlapping building elements when fixed in place. This may be achieved by the gates, compared to each other, having a reversed configuration of tightening mechanism extending between a distal end of the gate relative to a connection point on the main body.
