Mini-posts are 6mm diameter posts of stainless steel with an M4 male thread on one end and a small tightening hole near the threaded end. A range of lengths from 15 to 50mm is offered. They can be mounted onto the mini-carriers or directly onto the mini-baseplates by means of mini-post holders. The mini-post holders also have an M4 thread on one end and are supplied with a matching collar for ease of height maintenance. Mini-post holder lengths range from 15 to 40mm.

Mini-post bases are thin plates of aluminum which have an M4 threaded hole for the mounting of a mini-post or mini-post holder. They also have slots or clearance holes for mounting onto a mini-baseplate. Three types are offered: a simple base with slotted holes either side, an adjustable base with a single 15mm long slot, and a large base which will accept either a mini-post or a mini-stage. The bases are 5mm thick.

Mini-posts can also be connected by means of cross clamps for more versatile positioning of components. We offer two types of cross clamp. One is fixed and one includes an additional stub rod for attachment and rotation.
