Secure your hitch with a smarter design

The BOYISEN 5th Wheel King Pin Lock is built for standard king pins, delivering practical protection for your RV, trailer, or camper. Its solid steel body, weather-ready finish, and user friendly handles combine to create a deterrent that you can rely on during long trips and quick stops alike.

Upgraded design for easier locking

  • Enhanced handle and outward turning cylinder simplify locking and unlocking, reducing effort and strain.
  • Blossom lock with unique keys provides an extra layer of security and helps prevent accidental key duplication.
  • Heavy duty solid steel construction adds strength while resisting weather and tampering.
  • Coated finish guards against rust and corrosion, making outdoor storage more durable over time.
  • Key ID feature available on 2025 batches helps with key replacement by recording the ID on the key itself.

Security you can see and rely on

  • High visibility design serves as a clear reminder when the lock is in place, supporting safer hitching routines.
  • Blossom keying reduces the chance of cross matching with other locks in a fleet or community.

Rugged performance for all weather conditions

  • Solid steel construction is drill-resistant and built to endure road use and outdoor environments.
  • The protective coating helps resist the elements for longer life, even in humid or coastal settings.
  • Designed for versatile applications including RVs, boats, campers and semi-trailers, making it a practical option for fleets too.

Specs, fit, and what’s in the box

  • Dimensions: Height 93.5 mm; Inner diameter 74 mm; External diameter 150 mm.
  • Universal fit suitable for RVs, boats, campers and semi-trailers.
  • Package includes 1 king pin lock and 2 keys for immediate use.

Note: this lock can be part of a layered security approach for your equipment. It helps deter tampering and supports secure hitching, but it does not guarantee theft prevention. Always use as part of your broader security practices.
