A: This particular lock is narrow and would not fit if you can't connect together to secure lock.

**Q: Is this weatherproof?**
A: No the lock is not weatherproof. However, I spray the locks with a graphite lubricant. I spray the shackle with WD-40. I use these locks outdoors on my garbage cans as a deterrent for bears. They work for a long time, but there comes a time when you might have to saw them off. Have a cutoff tool, i.e, a grinder near by.
