Leviton Telcom L7737-100 Straight Strain Relief 2.5 Npt

Product Description

The LEVITON TELCOM L7737-100 is a straight strain relief fitting designed to secure and protect cables at entry and exit points on electrical enclosures, junction boxes, and wiring devices. It accepts a 2.5 NPT knockout opening and accommodates cable or conduit outer diameters from 1.94 to 2.06 inches. The fitting maintains a straight cable path, reducing mechanical stress on conductors at the point of termination. Electricians and low-voltage installers use this type of hardware accessory to maintain code-compliant installations and prevent conductor damage from vibration, pulling, or repeated flexing.

This strain relief is suited for commercial and residential electrical installations where cables enter panels, enclosures, or device housings through a standard 2.5 NPT threaded opening. It is appropriate for use in fixed wiring applications where a straight entry angle is required. Installation is typical in scenarios involving power wiring, control wiring, or communication cabling that must be mechanically secured at the point of penetration.

Installation Notes

Installation is performed by licensed electricians or qualified low-voltage technicians. De-energize all circuits and verify zero voltage before beginning work in any enclosure. Thread the fitting into the 2.5 NPT opening and tighten per the enclosure manufacturer guidance using appropriate hand tools. Work should comply with applicable NEC requirements for strain relief and cable protection at points of entry.
