The Tyler Tool High Security Stainless Steel Shutter Lock is a perfect fit for those looking for a higher level of security than a standard padlock can provide. Our lock is made from Type 304 Hardened stainless steel that significantly slows down attempts to cut the lock a with torches, abrasive and reciprocating saws. The stainless steel construction will also allow for a long service life even in the harshest outdoor conditions. The shutter lock design utilizes a bolt that spins to make it difficult to further guard against cutting tools. The Anti-Pick Disc Tumbler System and 3 precision cut keys is one of the most difficult systems to pick and require specialized tools much more rare and expensive than a typical lock pick set. After the criminals fail to pick the lock, they may try to drill the lock, but it is protected by an anti-drill spinner plate blocking the key-way. The large jaw opening allows for many chain configurations, but is still tight enough to deter cutting. This style of lock can also be referred to as a block padlock, straight shackle padlock, warehouse padlock, or close shackle lock.
