PACLOCK’s “PL410-PRO” – The New Industry Leading LOTO Padlock With over 200,000 possible key combinations, PACLOCK’s “PL410-PRO” quintuples what customers expect today from a typical safety lockout padlock. It is also the only product where small runs with custom keying or colors are available. Topping it all off, the PL410-PRO is the first and only thermoplastic padlock produced in the United States with some global components.

During the development process of the PL 410-PRO LOTO padlock, our design team re-engineered the pin technology to surpass industry norms and offer 200,000 key combinations while only using 7 pins. By limiting the length of the pins to 7, PACLOCK has done more with less and increased the lastingness of the PL 410-PRO, because any key with 8 pins or more is prone to breaking.

PACLOCK’S PL 410-PRO can be keyed-alike, master-keyed, and even grand-master-keyed. Custom, reserved keyways can be manufactured for large LOTO operations and alternate keyways will become available in the future to allow for an additional 200,000 key changes for each new keyway. As the only Lock Out Tag Out manufacturer that cuts keys, pins cylinders, and assembles LOTO locks in the U.S., PACLOCK has the ability to quickly answer custom keying orders in small sizes.
