A cup lock connection system for scaffold equipment advantageously has a locating arrangement for aligning ledgers, braces and other components on the cup lock at predetermined angular positions relative to the scaffold upright. The connecting ledgers, braces and other components preferably have a connecting head receivable on the cup lock connection in one of two orientations. In one orientation the aligning feature is active. In the second orientation the connection can be made without using the alignment functionality. |
