The coaxial-post adapter provided by LBTEK can clamp standard Ø12.7 mm posts. The grooves on the inner wall of the adapter's base form a dual-line contact with the post. The side features an M6 spring-loaded knurled hex thumbscrew for locking, which can be reinforced with a 5 mm hex wrench (Note: Excessive torque may cause the locking screw to break. It is recommended to use an L-shaped hex wrench and gently tighten by holding the short end). It is also compatible with 30 mm coaxial systems and can accommodate Ø25.4 mm optical components. For height adjustment, the mount base has a through-hole, allowing the post to pass completely through to the bottom for adjusting component height.
