Cylindrical holders for 12.7 mm diameter posts, made of high quality aluminum with bronze anchor threads, provide a lightweight and robust solution for any optical configuration. These holders allow the posts to be anchored directly to the table or to a base by means of an M6 thread, offering flexibility in mounting. The design includes internal machining that ensures that the 12.7 mm posts make contact on two support lines, ensuring a tight and precise fit. In addition, they allow you to vary the height of the posts, providing exceptional versatility to suit the specific needs of your optical system.
