max spade width for plastic covered binding posts

Thanks peoples, after more checking it appears that a spade with a 13.5mm width can be used the plastic shrouded posts :)

Yes, they seem like quite a nuisance and maybe not a good idea. Bananas are definitely easier :)

That sounds like a good idea :)

If necessary, since they are made of plastic, the spades can be made to fit by making the opening wider with small file. The only issue then is that the plastic shroud can't be rotated to different positions.

Did you have any issues once you removed the plastic shroud?
