Leviton Telcom L7715 Strain Relief Grommet 1/2 Wave

Product Description

The LEVITON TELCOM L7715 is a strain relief grommet designed to protect cables and wiring at panel knockouts, enclosure openings, and conduit entry points. It accommodates cable outer diameters from 0.437 to 0.562 inches, making it suitable for a range of low-voltage and signal cables. The half-wave design allows for snap-in installation without additional hardware, securing the cable jacket against abrasion and mechanical stress at the entry point. Electricians and low-voltage technicians install this fitting during rough-in and finish work on panels, junction boxes, and telecom enclosures.

This grommet is used in residential and light commercial wiring applications where cable protection at penetration points is required. Typical installations include structured wiring enclosures, telecom distribution boxes, and electrical panels where cables pass through metal or plastic edges. The half-wave profile seats into standard knockouts and secures the cable jacket to prevent chafing and pulling stress from transferring to terminations inside the enclosure.

Compatibility

Designed as an OEM-style strain relief grommet for use with standard panel knockouts and enclosure openings accepting cables in the 0.437 to 0.562 inch outer diameter range.

Installation Notes

Installation is performed by electricians or low-voltage technicians as part of panel or enclosure wiring. Power down or de-energize the enclosure before inserting the grommet and routing cables. Snap the half-wave grommet into the knockout opening before pulling the cable through to ensure proper seating. Follow applicable NEC requirements for cable protection and strain relief at enclosure entry points.
