Terminal Block Marking Tags
The CK series marker strips make circuit identification in a terminal block assembly quick and unambiguous. Each strip latches directly onto the terminal block, giving a large, high-contrast marking surface that stays legible for the life of the panel — so fault-finding and maintenance on individual components is faster and safer.
Available in six sizes covering terminal blocks from 2.5U to 70U, in both printed and blank versions. Printing can be horizontal or vertical, in 1 to 3 digits, using numbers, letters, symbols or any combination you specify.

Which size do I need?
Match the marker to the terminal block width, not the wire size. A 2.5 sq mm terminal block is a 2.5U block and takes a CK5. If you are unsure, send us a photo of the terminal block on WhatsApp and we will identify it for you.
