The cable holder is made of 2mm strong aluminium and thus is less prone to bending than steel cable holders.
For organizing patch cords it offers ten slots, each with a width of 3.8mm, which are compatible with the common minijack cables with a thin lead. You might squeeze in the 5mm thick NAZCA cables but this will frazzle the braided material which won't look nice. You should be able to organize cables with banana plugs with this holder as well.
Two mounting screws are supplied with the holder.
