Master Lock No 1 Commercial

[completia]

I have just received one of these lock and have been unable so far to open it. It is a commercial version, so I assume it is more pick-resist. Is there anything I need to know about this lock to effectively pick it?

The bars by the way are very long, longer than the average Master Lock.

I have 3 of the commercial MasterLock #1's that my work gave me. There is nothing special or pick resistant that I know of. Mine are a pain to single pin pick but I can rake them in under 15 seconds. Its just 4-pins. How loose the plugs are in these locks make it difficult to feel and keep the pins set.

I have a few of this commercial Master #1 and couples of commercial
Master #5 they are fair lock to pick using light, or medium tension would
do it sometimes dimond pick will work or short hook
other than that nothing special on this locks just take it easy and don't rush
hope this helps.

I also find them much easier to rake than pick due to how the plug fits.
