Great gym locks. I love the functionality.

  • Great for areas that need a lock and everyone who needs access can use the combo

Perfect replaceable locks that dont need a key, anyone with the combination at work can open our trash container with these

  • Works like a charm
Style: Set Your Own Combination, 2 Pack
These are pretty solid. Like how I can set my own combo. I've purchased about 6 of these over the years. After a season outside, the numbers get a little hard to turn. Just hit it with a little wd40 and you're good for another season

  • Scramble to combition if you leave the lock unlocked.
Style: Set Your Own Combination, 2 Pack
I love this combination lock, but there is one thing you should know and it is very important to know. When you leave the lock unlocked make sure you scramble the combination if it is left unlocked. Someone can walk up to your lock and read the combination on the lock if it is unlocked and open your lock later. ... show more

  • Good lock but lasted only a couple years.
Style: Set Your Own Combination, 2 Pack
Use it for my gym locker and worked well until it wouldn’t lock as I tried to push the lock shut. Tried silicone spray but didn’t help. Just got a new one.

  • Worst locks I've ever bought
Style: Set Your Own Combination, 2 Pack
This is a really bad product for outdoor use. I'm unable to open the locks after just a few months. They jam, got corroded its just a headache. Even the small key didn't open them. And this goes for both of them

  • Good price for a quality product
Style: Set Your Own Combination, 2 Pack
Bought these for an outdoor storage box. They seem high quality and so far they have not corroded.
