Marking Options
Standard Marking
Standard markings are applied directly to the side(s) of a
block. Standard color is white. Standard height is .125”.
Note: Blocks marked on both sides require a different
code for each side. Example Style L1 on one side of the
block requires Style L2 on the other side to ensure com-
mon terminal marking. To order, add appropriate suffix
(L1, L2, L3, L4, L5 and/or L6) to block part number in the
proper sequence.
Note: Not available on TB400 Series
