Technical Description
The rods feature a Ø12mm body with various length specifications (14.4mm to 50mm), enabling flexible installation and precise positioning in compact spaces. Each rod has an annular groove under the base and a Ø14mm base-type pedestal, compatible with M-BASE-S05 fork-shaped pressure blocks to lock the rod onto optical platforms or breadboards.


Made of 304 stainless steel, with an M4 threaded hole at the upper end and M6 thread at the bottom, for connecting different lens mounts and adjustment frames.

The pedestal is equipped with an annular groove, and when used with M-BASE-S05 fork-shaped pressure blocks, it offers multiple length options ranging from 14.4mm to 50mm.
