Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise this lock for its heavy-duty construction, exceptional bolt cutter resistance, and reliable outdoor performance. The compact shackle, enclosed disk design, and weatherproof keyhole cover earn consistent recognition for security and durability in harsh conditions. However, a notable minority report serious key issues including breaking, jamming, and difficult insertion. Despite these concerns, most customers consider the lock's strength and weather resistance well worth the investment for securing storage units and sheds.

nice lock, difficult packaging
Would RecommendThis lock was recommended for my self storage unit. Lock comes with two keys. The key turns smoothly when inserted in the lock. My only complaint is about the packaging: it is difficult to get the keys out of the packaging.

Not a good lock
Would Not RecommendI used this lock at my storage unit and the key got stuck in the lock. Good thing it got stuck im the unlocked position. Had the key gotten stuck in the lock in the locked position, i wouldnt have been able to get in my storage unit! I couldn’t turn the key or take it out the lock. So frustrating!! Had to go to the storage office, leaving my storage unit unattended and unlocked, and purchase a $20 lock from them.
Quality lock

Would Not RecommendLocked and unlocked your U-Haul trailer with the lock several times when loading for a recent move. We left out early the next day and traveled for a few hours. During the trip, we needed access to the trailer BUT the lock would not unlock with the key. After about 10 minutes of multiple attempts, the lock finally opened. Thinking that this was a one-time issue, I relocked the lock and again it would not open. Luckily, I had a different lock to get us through the rest of the trip. This item w...
