Leviton Telcom L7729-100 Strain Relief 1.5 Inch Npt

Product Description

The LEVITON TELCOM L7729-100 is a straight male double strain relief fitting designed for cable management and wire protection in electrical enclosures, junction boxes, and conduit systems. It features a 1.5 inch NPT thread for secure panel or enclosure entry and accepts cable or conduit diameters ranging from 1 inch to 1.13 inches. The double strain relief design distributes mechanical stress across two clamping points, reducing the risk of conductor damage at entry points. This type of hardware accessory is installed by licensed electricians and skilled tradespeople in both commercial and residential wiring applications.

Straight male double strain reliefs like the L7729-100 are used wherever cable or cord enters an enclosure, panel, or junction box and requires grip and bend protection. Typical installation scenarios include control panels, electrical enclosures, industrial equipment wiring, and low-voltage cable entries. The straight male configuration threads directly into a 1.5 inch NPT knockout or threaded entry, making it a common choice for clean, in-line cable routing where angled fittings are not required.

Key Features

• 1.5 inch NPT straight male thread for direct panel or enclosure entry
• Double strain relief clamping for distributed mechanical load on cable or cord
• Compatible with cable outside diameters from 1 inch to 1.13 inches
• Sold individually as a single unit (EA)
• Hardware accessory category fitting for standard electrical installation workflows

Compatibility

Designed as an OEM-style strain relief fitting for electrical enclosures, junction boxes, and control panels with 1.5 inch NPT knockout openings that require straight male double strain relief hardware.

Installation Notes

Installation is typically performed by a licensed electrician. De-energize all circuits and lock out the enclosure before installing or replacing strain relief fittings. Thread the fitting into the NPT knockout by hand first to confirm proper thread engagement, then tighten with an appropriate wrench to achieve a secure, rattle-free fit without over-tightening. Verify that the clamped cable falls within the 1 inch to 1.13 inch diameter range before finalizing installation to ensure effective strain relief.
