1.5 in Post
Base Lab Tools provides these Ø1.5" posts for building extended rigid structures. Typical applications include supporting aluminum breadboards above the optical table, building a framework from which to suspend optical components and creating instrument shelves upon or above the optical table.
Each PTB series Ø1.5" post is tapped with 1/4-20 tapped holes on both ends and a Ø1/4" cross through hole to provide leverage when securing the post. Posts can be stacked using 1/4-20 set screws (not included).
