Easy and quick to use snap-on markers are used in areas where wires have been connected or where a power system requires a constant connection. WICs have been specially designed to keep the markers in place even in installations with strong vibrations. A durable locking system prevents markers from sliding relative to each other and allows for the creation of clear marker blocks. For easier installation of markers, we recommend using the simple WICTOOL tool adapted to all sizes of WIC markers. Markers are used to mark already connected wires, mainly in control boxes of machines and when making electrical switchboards. Marker installation can be done manually or with the ergonomic WICTOOL tool.
