Marking Options & Accessories
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 number.
Special Marking
Special markings are available upon request at an additional charge
for preparation. Production charges for setup, handling and marking
are the same as for standard marking and the same quantity
discounts apply. Consult factory for price and delivery.
Standard Marking
Markings are applied directly to the sides of A0, CB0, A1, CB11, A2, LP2,
CB2, A3, LP3, CB3, A38, B38, A&B4. Standard characters are white and 1/8”
high. Factory may substitute 3/32” high characters.
