B-642 Application & Installation Blueprint
Self-Laminating Wire & Cable Marker • Physical application tolerances and surface engineering
Industrial Fit Certified
Self-Laminating 360° Overlap Wrap Installation
1Position the white opaque printable zone directly against the copper/PVC wire insulation.
2Wrap the cable firmly so the clear transparent overlaminate tail wraps 360° completely around the wire.
3Ensure the clear tail overlaps the printed text by at least 1/4" to seal against oils, solvents, and abrasion.
Engineering Tolerance: Recommended Overlap: 360° full circumference + 0.25" to 0.50" clear tail overlap.
