All customisation work is undertaken by the relevant supplier, (some smaller projects are done by utilizing outside contractors) at their own manufacturing facilities. These services include milling or punching holes and slots into the enclosure or end plates for cables, connectors, switches, etc. Printing and silk screening services allow for the addition of text, logos and graphics onto both the enclosure and end plates, to allow the end user to easily identify the product and also to give the final product a more elegant finish.
