• Material: 6061-T6 aluminium alloy
• Designed with precision-machined extra wide relief groove, the holders provide stable two-line contact with Ø12 mm posts.
• M6 threaded holes at the bottom or magnetic bases are provided for different modes of installation.

     The PSB series post holders are designed with through holes with M6 threads at the bottom and grooves on the inner wall to deliver two-line contact with the standard Ø12 mm posts while avoiding sliding and rolling of posts. Precision-machined knurled hexagon thumb screws can be further fastened by a 5 mm hexagon wrench. It is suggested to slightly fasten the locking screws with an L-shaped hexagon wrench; otherwise, excessive force will damage the locking screws. The ball head on the top is made of polyacetal to prevent the posts from being scratched. In addition, M6 threaded through holes are provided at the bottom of the holders. These holes allow holders to be fitted with LDB11 magnetic bases or LDB12 non-magnetic bases, or directly used with the LDA series mounts. Moreover, M6 screws can be used to fix holders onto the breadboards by running through the inside of post holders. Flexible installation on optical tables can also be achieved when these post holders are used together with LDA32 Ø12 mm fork-type pressing plates.
