Install whenever the trailer is parked at job sites, driveways, and storage facilities. Visible bright-colored locks deter opportunistic thieves. For maximum protection, pair a coupler lock with a wheel lock or boot. Match the coupler lock to your coupler type (2" or 2-5/16" ball, lunette ring, etc.).
