How can I tell if my banana fits in the banana hole?
The actual connector part will fit without problems - a 4mm banana connector always fits the same across all vendors.
Unfortunately the plastic protection is not standardized - I experience problems every now and then. Either the plastic is too long or the thicker part of the connector starts too early or the tiny plastic cap in the middle of the banana plug just got stuck in the socket. Some devices only accept straight connectors as well.
TL/DR: Impossible to say without actually trying it.
