Techflex DRN3.00BK-025 Dura-race Cable Protector 3 in

Product Description

The TECHFLEX DRN3.00BK-025 is a Dura-Race braided cable protection sleeve rated for demanding trade and industrial wiring applications. Sized at 3 inches in diameter and supplied in a 25-foot length, this black sleeve is designed to bundle, route, and protect cable runs from abrasion, chafing, and physical wear. Electricians, low-voltage installers, and panel technicians use this type of expandable sleeving to organize and protect conductors in conduit transitions, equipment cabinets, and raceway installations where exposed cables require mechanical protection.

This sleeve is suited for use in both residential and commercial electrical work, including HVAC control wiring, low-voltage data runs, power distribution harnesses, and equipment interconnects. The 3-inch diameter accommodates large cable bundles or individual large-diameter conductors. Supplied as a single 25-foot roll, it gives installers enough material to complete a full run without field splicing. Hardware and accessories installers working on structured wiring or equipment installations will find this format practical for job-site use.

Key Features

• 3-inch inner diameter accommodates large cable bundles
• 25-foot continuous length reduces field splicing
• Black finish provides a clean, professional appearance in finished installations
• Braided expandable construction allows easy cable insertion and routing
• Suitable for abrasion and chafe protection in conduit, cabinet, and open-air routing

Compatibility

Designed as a general-purpose cable protection sleeve compatible with standard electrical, low-voltage, and control wiring installations requiring 3-inch diameter braided sleeving.

Installation Notes

Installation is typically performed by licensed electricians or low-voltage technicians. De-energize all circuits before dressing or routing cables through the sleeve. Cut the sleeve to length using sharp shears and apply heat-shrink end caps or wrap the cut ends with electrical tape to prevent fraying. Follow applicable NEC guidelines for cable bundling and fill ratios in enclosed or conduit-fed installations.
