Siemon S110 wiring blocks allow for designation labels to be mounted between each row of connecting blocks or by utilizing the S110-LBL-T labels, directly on top of connecting blocks. The S110-LBL-T labels are ideal for use on the S110T Disconnect block or S110 Modular Jack Panels where labeling area is at a minimum. Each label has 2-, 3-, 4-, and 5-pair markings and can be used for color-coding.
