Hubbell LR320 Locking Ring 20 A 3-Wire

The Hubbell LR320 is a locking ring designed for 20 A 3-wire connectors in traffic and parking lot installations. It provides a secure mechanical lock for compatible wiring devices. The non-metallic composite construction resists impact in demanding outdoor environments. This accessory suits electricians and maintenance crews who need reliable connector retention.

IP67 sealing and temperature range

The ring carries an IP67 rating, protecting the connection against dust ingress and temporary water immersion. It operates continuously from -40 °C to 75 °C without degradation. The composite material does not conduct heat like metal hardware, so surface temperatures remain closer to ambient. No active cooling or power draw is involved because the part is purely passive.

Composite body and dimensional fit

The grey composite body measures 6.1 in long, 5.5 in wide and 1 in high, matching the envelope of standard 20 A 3-wire devices. Its impact-resistant formulation withstands physical abuse from vehicles or equipment. The UL Listing confirms compliance with relevant safety standards for the intended application. No additional tools or software are required for installation.

Questions about this item

How do I install the LR320 locking ring on a 20 A 3-wire device and what step is often missed?

Align the ring with the device's 3-wire interface, press it into place until the locking tabs engage fully, then verify the IP67 seal by checking the gasket sits evenly around the entire perimeter — the step most often missed is confirming the gasket is not pinched or twisted during installation.

What maintenance or replacement will the LR320 locking ring need over time?

Inspect the composite housing and gasket annually for UV degradation, cracking, or impact damage; replace the ring if the locking tabs show wear or the IP67 seal is compromised, as the composite material and gasket are the primary wear items under outdoor exposure.

What is the first performance limit the LR320 locking ring reaches under sustained outdoor use?

The IP67 seal typically fails first under sustained thermal cycling between -40 °C and 75 °C, as repeated expansion and contraction can degrade the gasket compression and allow moisture ingress before the impact-resistant composite housing shows structural fatigue.
