If you email them (shutter.company at msa.hinet.net) they will let you know
ie.
"Yes, we make 24H, 28H, 32H and 36H for PL-8. However, at this moment, 24H hub is out of stock. Sorry about this. If you can change to 28H, you can choose PL-8 in black, silver or red."
Does anyone know if this even exists:
SP9, silver, 28h or maybe 24h?
