Ordering options/part numbers

  • 35-946510 Combo Kit
  • 35-946520 2" Ball model
  • 35-946530 2-5/16" model

The preassembled configuration is not necessarily the one you will use. A shorter Bolt and companion Security Collar are also included to allow for multiple coupler configurations. The Coupler Vault Pro is designed to be universal and fit MOST trailer couplers.

The Security Collar is designed to fit loosely over the threaded Bolt to prevent any cutting device from gaining a ‘grip’.

IMPORTANT: The MegaHitch comes with two keys. It is highly recommended that you keep one key in a safe place in case the other key is lost or damaged.
