FBT AJ-5 MS 30BK Pole Adapter for J 5 Series

AJ-5 is the turned metal adapter FBT supplies so a J 5 cabinet can be mounted on an MS 30BK stand. The cabinet's own socket does not take a stand top directly; the AJ-5 drops in and presents an 18.5 mm spigot for the stand to take, which is the whole job.

It is a small part with a specific fit, and it is worth ordering by the FBT part number rather than substituting a generic pin. FBT catalogues it against the J 5, J 5T and J 5A, and it weighs 50 grams, so it lives in the accessory pouch rather than the case.
