The IT18R-NAT(100 PACK) is a Cable Tie for identification and securing of cable bundles, saving valuable installation time by using just one product to both secure and identify. They can be marked either on-site or after bundling has taken place. They can be marked manually using the T82S series of indelible marker pens. In addition there is a large selection of labels available for marking. One of the major benefits is the ability to both secure and identify cable bundles at different times.
