Marinco RV Power Inlet 30A 125V Easy Lock, Black — Quarter-Turn Watertight, Corrosion-Resistant

Marinco's Park Power 301ELRV.BLK is a rugged 30A, 125V Easy Lock RV power inlet that provides a fast, watertight shore power connection with a quarter-turn locking ring for secure hookup.

Built for demanding marine and RV environments, this inlet combines corrosion-resistant materials and an intuitive locking design to make shore power connections safer and faster. The inlet accepts standard 30A detachable cordsets and uses a soft-touch, contoured cap that stays open during connection and seals tightly afterwards. Its glass-filled polyester body and stainless-steel trim resist wear, while the Easy Lock mechanism reduces cross-threading and water intrusion.

How does the Easy Lock system make connecting shore power simpler?

The Easy Lock system shortens hookup time by using a locking ring that turns less than a quarter turn to secure the plug. This mechanism aligns the connector properly and prevents the common problems of cross-threading or loose electrical contact. It’s especially useful in low-light or cramped conditions where precise threading is difficult.

• Quarter-turn locking ring for rapid engagement
• Tabs on the ring ensure a consistent, watertight seal
• Reduces wear from repeated installations

Will this inlet stand up to outdoor, marine, and RV use?

Yes — the Park Power inlet is engineered for harsh settings with materials chosen to resist corrosion, impact, and ultraviolet exposure. The housing is molded from glass-filled polyester and finished with stainless-steel trim to extend service life in salty, wet, or dusty environments. The cap and locking features prevent water intrusion when not in use.

• Glass-filled polyester body for strength and UV resistance
• Stainless-steel trim to resist corrosion
• Waterproof cap and locking tabs to keep moisture out

Is the Park Power 301ELRV.BLK compatible with my RV power cord?

This inlet is sized for standard 30A, 125V RV power cordsets, so it accepts all Park Power detachable 30A plugs and compatible aftermarket cords. Wiring terminals are accessible for straightforward installation by a qualified technician, and the design accommodates common RV shore-power configurations.

How does the cap and overall design protect the inlet when not in use?

The contoured soft-touch cap stays open during hookup to avoid interference and closes smoothly to seal the inlet when idle. The cap’s ergonomic design makes it easy to operate with gloved hands, and the sealed closure helps block dust, rain, and spray. Together with the locking ring tabs, the cap contributes to a consistent, reliable watertight system.

• Soft-touch cap that remains open during connection and seals when closed
• Ergonomic shape for easy use with gloves or in low light
