1. Standards
These are the vertical members of a scaffold which are either supported on the ground or embedded in to the ground or rested on sand-filled bags.
2. Ledgers
These are the horizontal members of the scaffold.
3. Putlogs
These are transverse pieces which are placed on ledgers in perpendicular direction and supported on the wall.
4. Transoms
There are putlogs whose both ends are supported on the ledgers.
5. Bridges
These are used to bridge an opening in a wall and support one end of the putlog at the opening.
6. Braces
These are the cross or diagonal pieces fixed on the standards.
7. Guard Rail
This is a horizontal member provided like a ledger at the working level.
8. Toe Board
This is a board placed parallel to the ledgers and supported between the putlogs. This facility is made as a protective measure to work on the working platform.
