Abstract
A connection system is provided for use with scaffolding to secure laterally extending support members to upright standards. Latching rings permanently secured at intervals along the upright standards are provided with primary latching openings, each of which has a central region of limited breadth with oppositely directed narrower radial elongations of uniform width throughout. The radial elongations of the primary latching openings are located so as to reside in vertical registration with longitudinally elongated apertures formed in flanges of brackets that are secured to laterally extending scaffold support elements. Wedges are carried by the brackets and can be fully engaged only when the laterally extending support members are in precise, orthogonal alignment relative to the upright standards. Preferably, secondary latching ring openings are provided to accommodate diagonal braces to enhance the rigidity of the scaffolding support.
