    • Holding up so far on a car hauler trailer
Style: Combination Lock, 1 Pack
I use these to lock the ramps on my car hauler trailer. I have had to cut different locks off it over the years as they stop working over time because they get corroded and gummed up from the elements. Ive had these now for about 2 years and they have held up well. A little tip I have is to wrap around the bottom side with electrical tape to seal off where the combination changing key goes into the lock to keep water, dirt and dust out of them if used outside. This seems to have helped keep them working longer in my experience. ... show more

    • This model remedies previous bypass exploit
Style: Combination Lock, 1 Pack
If you watch lock picking videos online, such as The Lockpicking Lawyer, this model remedies the bypass exploit of previous models. This lock cannot be shimmed or bypassed as easily as previous models.

    • Quality lock
Style: Combination Lock, 1 Pack
Picked this lock to use as my gym lock. Feels heavy and quality. Except it appears that it's not hard to bypass these locks so it's more of a deterrant if anything
