A scaffolding ( 10) for elevating a worker (not shown) above a floor or ground surface is disclosed. The scaffolding (10) broadly includes a pair of frames (12) and (14), cross bracing (16) coupling the frames (12,14) together, and a plurality of walkboards (18, 20, and 22) removably supported between the frames ( 12,14). Each of the frames ( 12,14) includes a plurality of slotted ledgers (32, 34, 36, 38) and (40, 42, 44, 46) coupled to and extending horizontally between corresponding support posts (24,26) and (28,30), respectively. Each ledger is configured to facilitate initial assembly of the frames ( 12,14) and to prevent undesired shifting of a walkboard supported thereon. For example, the ledger (38) is defined by a U-shaped wall (60) that presents an arcuate walkboard bearing support surface (62) having open, recessed slots (64,66,68,70,72) defined therein. Each slot is configured and dimensioned to receive a portion of the supported walkboard and prevent shifting of the walkboard along the ledger axis.
