A great peace of mind
[This review was collected as part of a promotion.] Living in a rural area and being farmers; it’s not uncommon for us to leave a truck parked in a field all day or even through the night. We can lock the doors and take the keys out but we’ve forgotten to remove hitches. They weren’t on the truck when we came back the next morning. This is a simple lock, that keeps our hitches on OUR vehicles. Easy to install and easy to unlock. Protect your hitch and invest in this lock.

Love it
[This review was collected as part of a promotion.] Really was sold on the locking rails on the too so I only need one wrench to tighten down the ball. Also, the pin design is next to amazing on how I can us both large and small receivers. Also I like that it is a wide throat shaft for ball as well.

Economical Insurance
The TowSmart Brand, Locking Boomerang Hitch Pin is an affordable, versatile, locking hitch pin. I needed two to use with a hitch extension and motorcycle carrier and was able to find two with the same key number. The key number is a four-digit number stamped on each key. I tried the key of one hitch pin in the other hitch pin and it worked perfectly. However, when I arrived home, the hitch pin I did not try, the keys, both, the ones supplied and the keys of the other hitch pin, were difficult to insert and remove. The keys are easy to try in the store as they are secured with a twister seal. I didn’t want to return the stiff lock as having both keyed the same was more important. It works OK with a bit of fiddling. The pins seem strong, although I wasn’t towing with them. The lock cylinders themselves come with weather seals, a rubber O-ring on the pin and a rubber cap over the key slot. All locks can be defeated with enough effort. However, the extra security these locking hitch pins provide for their cost is economical insurance. These hitch pins did fit my two-inch class IV receiver hitch and class III extension perfectly.
