The most common panel mount fuse holder supports a 3AG fuse and requires a 'D' cut-out in the panel.
The cut-out is .475in ['D' side] x .502in [round]. A another common type of cut-out has a flat side on both the right and left side, .461 x .502
When selecting a fuse holder be sure that the holder can withstand the maximum fuse rating for voltage and current.
The fuse holder could melt trying to with stand the power dissipated by the fuse before the fuse opens.
