Abstract: A holder for an implement such as a mortar board which is to be horizontally positioned, comprises a back plate having slots which receive a worker's belt so that the holder can hang on the belt and an L-shaped frame which has a vertical portion selectively attachable to the back plate and a horizontal portion which has two elongated supporting arms which protrude outwardly away from the back plate and are disposed in spaced relationship. The handle of the mortar board is inserted into the space between the arms so that the flat board rests on the two supporting arms. When the handle is engaged between the two supporting arms and the board rests on the supporting arms, both hands of the worker are free to conduct other operations.
