UCP have a unique core tray end label. The ends of the core trays are made of shatter proof strong plastic. They each feature an embossed suraface with empty digital font text fields present. Allowing users to write in core trays data, such as the project code and tray number. The font eliminates personal users hand writting, thus making it the text easier to read on site and well into the future. Therefore eliminating potential misunderstanding.
