Standard Marking
Blocks to be marked on both sides require a different code for
each side. Example: “L1” on one side of the block requires “L2” on
the other side to ensure common terminal marking. Specify by
adding suffix to part no.
Markings are applied directly to the sides of Series 1000, 2000, 3000,
4000 & 5000. Standard characters are white and 1/8” high. Factory may
substitute 3/32” high characters.
