Does anyone have info on this series of padlock please?
How secure, number of pins and type. Will they bump? etc

Thanks

Definitely bumpable. They are also able to have cylinders replaced by HS cylinders. Great quality padlock for the price point. Beautifully constructed. I especially like putting Bilock cylinders into these. Makes them bump proof and virtually pick proof for about $80 each.

I have 4, 3of them are the 6121 and i have 1 911. The 6121s have 5 spool top pins and 4 of the 5 bottom pins are serated. They all can be bumbed but great locks one of my faves.

The 6121: "Info from master lock"

Hardened boron alloy shackle for superior cut resistance
5-spool pin tumbler cylinder for added pick resistance
Removable cylinder can be replaced or repinned
Dual ball bearing locking mechanism resists pulling and prying
Body and cylinder covers protect locks from water, dirt and grime
Heavy steel bodies withstand forcible attacks
