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 mechanism for connecting two beams comprises a left beam and a right beam. The left beam is formed by an upper cross bar, a lower cross bar, and a vertical plate, the vertical plate has a width greater than a width of the upper cross bar and a width of the lower cross bar, the vertical plate has two edges protruding laterally away from the upper cross bar and the lower cross bar; the right beam has a vertical socket for receiving the vertical plate, the vertical socket is connected to the upper cross bar and to the lower cross bar, the vertical socket has two opposing curled lateral edges protruding laterally away from the upper cross bar and the lower cross bar, the two protruding edges of the vertical plate are inserted between the two opposite curled edges of the vertical socket.

A fastening unit for attaching a first beam to a second beam is provided, wherein the second beam is arranged substantially perpendicularly to the first beam, the fastening unit having a first axis and a second axis, wherein the second axis is substantially perpendicular to the first axis. The fastening unit comprises a connecting member extending in a direction parallel to the first axis of the fastening unit and having a first edge portion, a second edge portion and a central portion, the connecting member further comprising a coupling element.

Disclosed herein is an adjustable shoring beam having a hook assembly configured to mate with E-track mating features. The adjustable shoring beam can be adjusted over a predetermined length range by adjusting the tube assembly and the rod assembly. In some embodiments, the extension length is fixed using a fixing clamp coupled to the tube assembly and the rod assembly. A connecting clamp and bracket may be used to couple a first adjustable shoring beam to a second adjustable shoring beam.

A holder assembly for holding multiple wiper assemblies includes a plurality of end spacers adapted to contact and separate wiper assemblies at a toe and heal thereof and a center clamp adapted to be disposed about and retain the wiper assemblies together.
