Leviton L8011-100 Strain Relief Cord Connector, 1.5" NPT

The Leviton L8011-100 is a strain relief cord connector engineered with a 1.5" NPT thread for secure mounting into enclosures, panels, and equipment housings. This connector is sized for a cable diameter range of 1.31" to 1.44", ensuring a snug, dependable grip that protects the cord jacket from abrasion, pull-out, and repeated flexing at the point of entry. Built by Leviton for demanding commercial and industrial wiring applications, the L8011-100 delivers reliable mechanical strain relief wherever cordage must pass through a metal or plastic enclosure wall.

Leviton L8011-100 – Frequently Asked Questions

1) What cable diameter does the Leviton L8011-100 strain relief connector accept?
The L8011-100 grips cord jackets measuring 1.31 to 1.44 inches in outside diameter. That is the compression range, so a cord thinner than 1.31 inches won't clamp tight enough to hold against pull-out, and anything over 1.44 inches won't seat in the gland. Measure the jacket OD, not the conductor size, before you order.
2) Will a 1.5 inch NPT strain relief connector thread into my enclosure knockout?
The L8011-100 has a 1.5 inch NPT male thread, which mates with a tapped 1-1/2 inch NPT hub or a 1-1/2 inch trade size knockout fitted with the matching locknut arrangement. A 1-1/2 inch knockout is a standard trade size, so the hole itself is common on panels and junction boxes, but confirm your opening is 1-1/2 inch trade size and not 1-1/4 or 2 inch, since NPT threads are not interchangeable between trade sizes.
3) What does a strain relief cord connector actually do at the panel entry?
It clamps the cord jacket where the cable passes through the enclosure wall so the mechanical load stays on the fitting instead of the terminations inside. The L8011-100 takes the pull, the flexing, and the abrasion at the entry point, which is what keeps conductors from backing out of terminals on equipment that moves or gets its cord tugged. A plain bushing or chase nipple protects the hole edge but gives you no grip on the cord.
4) What is the Leviton part number to order for a 1-1/2 inch NPT strain relief connector?
Order Leviton L8011-100. That single catalog number covers the 1.5 inch NPT body with the 1.31 to 1.44 inch cord range, so there is no separate size or finish to specify.
5) Is this the right fitting for cord entry on a control panel or machine wiring?
Yes, that is the intended use. Leviton lists the L8011-100 for commercial and industrial enclosures, panel and equipment cord entry points, machine and equipment wiring, control panel installs, and general cord management. The deciding factor is the cord, not the application: the jacket has to fall between 1.31 and 1.44 inches OD and the panel needs a 1-1/2 inch NPT opening.
6) Can I use the Leviton L8011-100 on a plastic enclosure, or is it for metal only?
Either. The connector is built for cordage passing through metal or plastic enclosure walls, so it works on fabricated steel panels, cast housings, and nonmetallic boxes alike, provided the hub or knockout is a tapped 1-1/2 inch NPT opening.
