ZWO Spare Silver (Aluminium) Plate for TC40 Carbon Fibre Tripod

This is a spare top plate for the ZWO TC40 tripod, made of high quality aluminium . 

For example, if you have two different mounts and wants to swap between them then it might be convenient to have such a top plate attached to the bottom of both mounts for quickly changing the mounts if you otherwise have only one tripod.
