  1. Verified Customer ✔️ (store manager)

    The spin discourages theft!

  2. Verified Customer ✔️ (store manager)

    Well made and I like the cover over the key hole.

  3. Verified Customer ✔️ (store manager)

    Worked well for me. I have a 2 part drop hitch on my truck and wanted to lock it down so I don’t have to keep taking it off and on to keep it from getting swiped. Cap over keyhole is good idea too.

  4. Verified Customer ✔️ (store manager)

    Fit great , love it.

  5. Verified Customer ✔️ (store manager)

    Like the sliding lock protector. Better than the ones with plastic caps which over time shrink/tear.

  6. Verified Customer ✔️ (store manager)

    I have actually bought 3 of these things, for different trailer hitch setups. They are nice looking chrome, but don’t leave them out all the time or they will rust. The lock part clicks on without needing the key, and the keyhole faces you, making it easy to remove.

  7. Verified Customer ✔️ (store manager)

    Great quality, Great price, eady to use

  8. Verified Customer ✔️ (store manager)

    Great price and surprisingly durable!

  9. Verified Customer ✔️ (store manager)

    Works as advertised. Dust cap is durable and stayed in place after 1 000 mile tow.

  10. Verified Customer ✔️ (store manager)

    Needed to replace the pins for my trailer ball hook ups on my trucks. These work great and easier to lock and unlock too.

  11. Verified Customer ✔️ (store manager)

    Unlocks easy , locks without key with just pushing on , could use better design to seal out moisture, overall ok Mines a 5/8″ dia.

  12. Verified Customer ✔️ (store manager)

    My trailer hitch was stolen by meth-heads and sold for scrap metal on numerous occasions. I finally bought this lock and now I can sleep at night knowing that some random person can’t just take my hitch and sell it on the black market.

  13. Verified Customer ✔️ (store manager)

    No problem ?

  14. Verified Customer ✔️ (store manager)

    yes would buy again

  15. Verified Customer ✔️ (store manager)

    Good product at a good price.

  16. Verified Customer ✔️ (store manager)

    Inexpensive way to secure your hitch without breaking the bank.

  17. Verified Customer ✔️ (store manager)

    I have had the other lock pin but you couldn’t get the key in after while the lock was rusted up. This one has a cover for the lock hopefully this fixes the issues I had before.

  18. Verified Customer ✔️ (store manager)

    Design is excellent and looks great

  19. Verified Customer ✔️ (store manager)

    Rotating lock improves easy of use.
