Below are links to a few photos of the lock. Shipping was quick but at a cost of about $53 USD. There was also a slightly cheaper UPS option at $35 USD but I was worried about larger brokerage fees. As it turns out even with USPS I got hit with $24 in taxes and customs fees.
Some of the Proven Industries locks are also supposed to be able to fit the safety chains but there wasn't enough room in the 2516-A version.
I have not had a chance to use the lock much so maybe after a couple camping trips I will post any more comments if I have them.
The lock fits well and seems very secure. It seems like its the most secure hitch lock on the market but at a really high cost. By the time you add up the cost of the lock, shipping, conversion to CAD and the customs fees its a lot of money for a lock.
