The optical post holders can be fixed to the optical table and moved to the right or left with the optical table swivel-base adapter.
This adapter has a slotted rotatable base for M6 cap screws. This slot is compatible with our standard M6 optical tables and provides easy access to the mounting holes around the rotation design of the base. To use the minimum height of a post, these table holders have a hole that allows them to sit on the optical table.
