American Lock Master Lock S1106YLW S-Series Aluminum Safety Padlocks Yellow, 1.5" Shackle

I purchased this S1100 lock and it works just fine.To be clear, this is not the A1100 model some people seem to be looking for. The S1100 is the same aluminum lock body but it uses the core found in the Master Lock #410 lockout/tagout lock (LOTO) lock. As such, it will have have a Master Lock key and will only come with a single key, as is the case with most LOTOs. The core and pins are different but they offer similar levels of pick-resistance. Master Lock and American are owned by the same company.

Now THIS is a lock to up your picking skills! 6 pin tumbler lock filled with security pins. Mine had 5 spools and one serrated pin. Have cracked a number of ABUS locks and even a ML410, but this one's eluded me so far. Highly recommended for those who want to up their locksporting skills.

This lock is supposed to come with two keys but I only got one. I cant help but feel this is a used lock because the box looks like its been opened before. I am a little upset over it but not enough to refund it. Otherwise great delivery time and product.

Hey locksporters!This is not the average American 1100. This is an "S" 1100, not the "A" 1100.This lock combines the American 1100 series lock body with the Master Lock LOTO lock key cylinder. This is the same 6-pin cylinder that is considered one of Master Lock's most secure cylinders, but is normally found in the plastic 410 LOTO locks. Hence, the paradox.If one is looking for an alternative to the normal American lock cylinders, and are interested in the 410 cylinder in a more secure lock body, then this is the one to get!

its a fun lock to pick, but it is not the one with the normal American lock, this is the one with the Master Lock LOTO core
