The MegaHitch Lock Coupler Vault II universal trailer lock fits ALL standard hitches with its 2" to 2 5/16" included ball.  The 5-sided, metal trailer lockbox secures yachts, construction materials, and valuables with the unbreakable design that keeps your tow ball untouchable.

The Coupler Vault Pro™ has been designed to be seamlessly installed on trailers with its 2" to 2 5/16" hitch ball.

The vault has a 2" and 2 5/16", high-density acetate ball that fits perfectly into your trailer's tongue, just like having it hooked up to your vehicle.  The ball provides even stronger resistance to wiggling and jimmying with adjustability.  Even when the latch is undone on your vault the ball securely fits into your socket.

A new cam lock positioning mechanism has replaced the old, plunger style post-lock.  The cam lock surrounds the post with a stainless steel ring and prevents chisels from getting up and underneath the bolt to remove it with jarring force.

In addition, the steel security rings encasing the bolt keep thieves from being able to position any reciprocating saws or grinders in the encasement.  The taper design makes the cutting edge simply slide out.

The entire vault is constructed as a puzzle to slot into itself and provide very little dead space for entry with prybars or bolt cutters.  There are vertical plates that extend over the lid and strengthen the integrity of the lock, providing self-bracing support that only gets stronger the more you wrench at it!

Please note that this UNIVERSAL HITCH LOCK works on most standard units which may not include obsolete or off-size trailer hitches!

Used in conjuction with the MegaHitch Lock 3 - 4 inch Bolt and Breakaway Nut Kit or MegaHitch Lock Breakaway Security Nuts, the Mega Hitch Lock is functionally impregnable.

Customer Reviews

Coupler Vault
It is the most secure locking system I have seen so far. Have had one trailer stolen with conventional coupler ball lock. Hope this unit will save my new trailer.
