Multiple Mounting Plates ST-2MP allows the assembly of groups of accessories mounted in close proximity to act as one unit (e.g. a compound lens). For example, the slot of the plate ST-2MP allows the mounting of lens holders ST-4LM149 using M6 screws from beneath. Their positions can be adjusted on the plate. The ST-2MP can be attached to tables, breadboards and rods. The ST-2MP is suitable for metric and inch applications.
