A marker system for pipes or valves comprises a tape having a surface layer and a pressure sensitive adhesive layer, the tape defining spaced-apart transparent window areas. A release paper backing is deployed on the adhesive layer of the tape, and the release paper backing includes pre-cut window backing portions generally registered with the transparent window areas of the tape. The pre-cut window backing portions may be joined with the release paper backing along a hinge/tear line whereby the window backing portions may be folded away from the tape. The marker system further comprises information cards sized to be adhered in the transparent window areas of the tape. The marker system is installed by first removing or folding back the pre-cut window backing portions of the release paper backing and adhering the information cards in the window area. The marker system may be installed by thereafter removing the remainder of the backing paper as the tape is wrapped around the pipe for marking the pipe or an adjacent valve; however, in marker systems where the window backing portions are hinged to the remainder of the release paper backing, the window backing portions may be positioned over the information cards, covering any exposed adhesive, and the marker system may be rolled up for storage or shipment prior to installation. In one embodiment, the release paper backing is provided in segments with alternate segments providing the window backing portions. The marker system is cut to length for installation around a pipe with the cuts being made through a blank segment of the release paper backing, so that the portions of release paper backing adjacent the ends may be removed for adhering the length of marker system to a pipe.
