Pro-source TSL-100-M-MB-PRO Standard Cable Tie 4in Black

Product Description

The PRO-SOURCE TSL-100-M-MB-PRO is a standard-duty nylon cable tie designed for bundling and securing wire harnesses, conduit runs, and general fastening tasks in electrical, HVAC, and mechanical installations. At 4 inches in length with an 18-pound tensile strength, this tie handles light to moderate bundling loads without bulk. Made from black nylon, it carries a UL 94 V-2 flame rating and meets MIL-SPEC standards, making it appropriate for both commercial and industrial service work. Electricians, HVAC technicians, and general contractors keep these on hand for everyday wire management tasks.

These cable ties suit residential and light commercial applications where a compact, reliable fastener is needed. Common uses include securing low-voltage wiring, bundling thermostat leads, organizing control board harnesses, and routing conduit support loops. The black nylon construction offers moderate UV resistance compared to natural nylon, making it a practical choice for exposed interior runs and equipment enclosures. The maximum bundle diameter of 21 millimeters fits most small to medium wire bundles encountered in standard service calls.

Installation Notes

Cable ties are installed by hand or with a tensioning tool; a flush-cut tool or side-cut pliers should be used to trim the tail after cinching to avoid sharp edges that can damage wire insulation or cause injury. Power down any panel or control board before routing or bundling wiring inside enclosures. Follow NEC requirements for securing and supporting conductors when used in electrical installations. Do not over-tension ties on insulated conductors, as excessive force can damage jacket integrity.
